Understanding Kiwi Fruit Pollination And Compatible Varieties
BERRIES AND VINES
Kiwi fruit (Actinidia spp.) is a popular and nutritious fruit known for its unique flavor. This long-lived, vigorous, fruiting vine is native to certain regions of China and parts of Southeast Asia, where it has been cultivated for centuries. Achieving successful kiwi fruit production requires not only an understanding of the plant’s growth habits but also a clear knowledge of its specific pollination needs and the selection of compatible pollinators.

In this article we explain how kiwifruit pollination works, and provide a comprehensive list of known fuzzy and hardy kiwi fruit varieties and their compatible pollinators.
The Biology of Kiwi Fruit Pollination
Kiwi plants are dioecious, meaning that a plant is either male, and produces male flowers, or is female, and therefore only produces female flowers, but not both. For fruit production, both male and female plants are required, the female plants produce the fruit while the male plants pollinate them.
In kiwi plants, male flowers produce pollen, while female flowers produce the fruit. For fruit to set, pollen from the male flowers needs to be transferred to the female flowers. This process of cross-pollination is mainly carried out by wind and insects, such as bees, which help carry the pollen from male to female flowers.
▲Use of kiwi pollination tools
Generally, one male kiwi vine can pollinate up to six to eight female vines. For effective pollination and maximize fruit production, it’s important to plant the male and female vines within 9-15 meters (30-50 feet) of each other.
Pollination Compatibility in Kiwi Fruit Varieties
For successful pollination and fruit production, it’s important to select compatible male and female kiwifruit varieties, you can’t just use any one. The primary factor in determining compatibility is the timing of flowering. For pollination to occur, the blooming periods of the male and female plants need to overlap, so that pollen from the male flowers is available when the female flowers are receptive (open), allowing for effective cross-pollination.
▲Kiwi Pollination
Timing of Kiwifruit Flowering:
Kiwi varieties can be classified into early, mid, or late-season flowering types based on when they flower during the growing season. For instance, a female kiwi vine that blooms early in the season, needs to be paired with a male variety that also blooms early in the season so their flowring coincides. If the male and female plants don’t flower at the same time, the chances of successful pollination are significantly reduced, leading to poor or no fruit set.

Other Factors:
In addition to flowering timing, there are other factors that can influence pollination compatibility, such as:
Species Compatibility – Fuzzy vs Hardy Kiwifruit:
Different species of kiwi (e.g., Actinidia deliciosa (fuzzy kiwi) and Actinidia arguta (hardy kiwi)) may not always be cross-compatible. When selecting varieties, it’s important to choose male and female plants from the same species to ensure effective pollination.

Pollen Viability:
The viability of the pollen, or its ability to fertilize the female flowers, can vary between varieties. Some male plants produce more viable pollen than others, which can impact the pollination success rate.
Environmental Conditions:
Environmental factors such as temperature and humidity can also affect the flowering period and the viability of the pollen. For example, if a male plant blooms during a cooler period while the female plant blooms in warmer weather, the mismatch in environmental conditions could reduce pollination effectiveness.
For successful kiwi fruit production, it’s essential to select male and female varieties that flower simultaneously and belong to the same species.

Compatibility Between Fuzzy and Hardy Kiwis
Fuzzy kiwi (Actinidia deliciosa) and hardy kiwi (Actinidia arguta) are distinct species within the Actinidia genus and are generally not cross-compatible for pollination. This means that male fuzzy kiwi vines cannot pollinate female hardy kiwi vines and vice versa. When planning your kiwi orchard, it’s important to pair male and female plants within the same species to ensure successful fruit production.
Some hardy kiwi varieties, such as ‘Issai,’ are self-fertile, meaning they can produce fruit without a male pollinator. However, even in self-fertile varieties, having a compatible male plant nearby can increase yield and improve the size and quality of the fruit.
Known Hardy Kiwi Varieties and Their Pollinators
For successful cultivation and optimal fruit production of hardy kiwi, it’s important to match female varieties with their appropriate pollinators.

Pollination Mechanisms in Kiwi Plants
Pollination in kiwi plants is primarily achieved through the movement of pollen from male flowers to female flowers, a process known as cross-pollination. The most effective pollinators are bees, which transfer pollen as they move from flower to flower. Wind also plays a role, though it is less effective compared to insect pollination due to the relatively heavy pollen grains produced by kiwi plants.
To maximize pollination efficiency, it is important to maintain a healthy population of pollinators in the orchard. Encouraging native bees and other pollinating insects by planting nectar-rich flowers nearby can enhance pollination rates, leading to better fruit set.
Pollen Viability and Longevity
The viability of kiwi pollen can be influenced by several factors, including temperature, humidity, and the age of the pollen. Kiwi pollen is most viable when freshly produced and under optimal conditions, it can remain viable for several days. However, prolonged exposure to high temperatures or very dry conditions can reduce its viability, leading to lower pollination success.
To ensure effective pollination, it’s important to time the blooming periods of male and female plants so that the female flowers are receptive while the pollen is still viable. This timing is particularly critical for varieties with shorter blooming periods.
Impact of Hot and Windy Conditions:
Hot and windy conditions can further challenge pollen viability and pollination. High temperatures can cause pollen to degrade more quickly, reducing its effectiveness, while strong winds can physically displace pollen, making it less likely to reach female flowers. Additionally, these harsh conditions can create inhospitable environments for pollinators like bees, reducing their activity and further limiting successful pollination. This underscores the importance of selecting appropriate planting locations and considering environmental factors to optimize pollination.
Impact of Pollination on Fruit Quality and Yield
Successful pollination is directly linked to the quality and yield of kiwi fruit. Well-pollinated flowers tend to produce larger, more uniform fruits with better flavor and higher nutritional content. In contrast, poor pollination can result in smaller, misshapen fruits or even fruit drop.
For commercial growers, achieving consistent and thorough pollination is crucial for maximizing marketable yield. This involves not only selecting the right varieties and ensuring overlap in flowering times but also managing orchard conditions to support pollinator activity and pollen viability. Ensuring adequate shelter from harsh winds, maintaining optimal temperature and humidity levels, and providing ample water sources can create a more favorable environment for pollinators like bees. Additionally, planting flowering plants that attract pollinators and minimizing the use of harmful pesticides can further enhance pollination success.
Optimizing Kiwi Vine Productivity with Pruning and Flowering Wood Management
Kiwi flowers develop on one-year-old wood, which is wood that grew during the previous season, making this growth crucial for successful fruit production. As kiwi vines are vigorous growers, they generate significant new wood each season, but older wood (more than one year old) typically becomes less productive, bearing fewer flowers and fruit. To maintain high yields, it’s essential to regularly prune the vines, focusing on removing older, non-productive wood and encouraging the growth of fresh, fruit-bearing shoots.
This practice, known as “cane replacement,” involves cutting back old canes during the winter dormancy period, allowing new canes to develop and become the primary fruiting wood for the upcoming season. By continuously replacing old wood with new growth, the vine remains vigorous and capable of producing abundant fruit each year.
Summer pruning plays an equally important role in maintaining vine health and productivity. By removing excess growth during the growing season, summer pruning improves air circulation and light penetration within the canopy, which helps to reduce the risk of fungal diseases and ensures that all parts of the vine receive adequate sunlight. This not only supports the development of high-quality fruit but also contributes to the overall vitality of the vine, making it more resilient to environmental stresses.
Regular, well-timed pruning ensures that kiwi vines remain productive year after year, producing large, flavorful fruit while maintaining their health and vigor. Understanding and implementing these practices is key to successful kiwi cultivation, whether in a commercial orchard or a home garden.
In conclusion, by carefully selecting compatible male and female varieties, ensuring their flowering periods overlap, and maintaining favorable conditions for pollination, growers can significantly enhance both the yield and quality of their kiwi fruit. Additionally, regular and strategic pruning is essential for renewing fruiting wood and sustaining long-term productivity. By integrating these practices, whether in commercial orchards or home gardens, growers can enjoy abundant and high-quality kiwi harvests year after year.
了解獼猴桃授粉和兼容品種
獼猴桃（Actinidia spp.）是一種受歡迎且營養(yǎng)豐富的水果，以其獨(dú)特的風(fēng)味而聞名。這種長壽、充滿活力、結(jié)果的藤蔓植物原產(chǎn)于中國某些地區(qū)和東南亞部分地區(qū)，在那里已經(jīng)種植了幾個(gè)世紀(jì)。實(shí)現(xiàn)獼猴桃的成功生產(chǎn)不僅需要了解植物的生長習(xí)性，還需要清楚地了解其特定的授粉需求和選擇兼容的授粉者。
在這篇文章中，我們解釋了獼猴桃授粉是如何工作的，并提供了一份已知的模糊和耐寒獼猴桃品種及其兼容授粉者的綜合清單。
獼猴桃授粉生物學(xué)
獼猴桃植物是雌雄異株的，這意味著一種植物要么是雄性，產(chǎn)生雄花，要么是雌性，因此只產(chǎn)生雌花，而不是兩者都產(chǎn)生。為了生產(chǎn)水果，需要雄性和雌性植物，雌性植物生產(chǎn)水果，而雄性植物為它們授粉。
在獼猴桃植物中，雄花產(chǎn)生花粉，雌花產(chǎn)生果實(shí)。為了坐果，雄花的花粉需要轉(zhuǎn)移到雌花上。這種異花授粉過程主要是由風(fēng)和蜜蜂等昆蟲進(jìn)行的，它們幫助將花粉從雄花帶到雌花。
一般來說，一棵雄性獼猴桃可以為多達(dá)六到八棵雌性獼猴桃授粉。為了有效授粉并最大限度地提高果實(shí)產(chǎn)量，將雄性和雌性葡萄藤種植在相距9-15米（30-50英尺）的范圍內(nèi)非常重要。
獼猴桃品種授粉親和性研究
為了成功授粉和果實(shí)生產(chǎn)，選擇兼容的雄性和雌性獼猴桃品種很重要，你不能只使用任何一種。決定兼容性的主要因素是開花時(shí)間。為了進(jìn)行授粉，雄性和雌性植物的開花期需要重疊，這樣當(dāng)雌花開放時(shí)，雄花的花粉就可以被利用，從而實(shí)現(xiàn)有效的異花授粉。
獼猴桃開花時(shí)間：
獼猴桃品種可以根據(jù)生長季節(jié)開花的時(shí)間分為早、中、晚三種開花類型。例如，在季節(jié)早期開花的雌性獼猴桃藤需要與在季節(jié)早期也開花的雄性品種配對，這樣它們的開花時(shí)間就一致了。如果雄性和雌性植物不同時(shí)開花，成功授粉的機(jī)會(huì)就會(huì)大大降低，導(dǎo)致坐果不良或沒有結(jié)果。
其他因素：
除了開花時(shí)間，還有其他因素會(huì)影響授粉兼容性，例如：
物種兼容性——模糊獼猴桃與耐寒獼猴桃：
不同種類的獼猴桃（例如，美味獼猴桃（毛茸茸的獼猴桃）和軟棗獼猴桃（耐寒的獼猴桃）可能并不總是交叉兼容的。在選擇品種時(shí)，從同一物種中選擇雄性和雌性植物以確保有效授粉非常重要。
花粉活力：
花粉的活性，或其使雌花受精的能力，可能因品種而異。一些雄性植物比其他植物產(chǎn)生更多的活花粉，這會(huì)影響授粉成功率。
環(huán)境條件：
溫度和濕度等環(huán)境因素也會(huì)影響花粉的花期和存活率。例如，如果雄性植物在較冷的時(shí)期開花，而雌性植物在較暖的天氣開花，環(huán)境條件的不匹配可能會(huì)降低授粉效率。
為了成功生產(chǎn)獼猴桃，選擇同時(shí)開花且屬于同一物種的雄性和雌性品種至關(guān)重要。
已知獼猴桃品種及其傳粉者
在購買和種植獼猴桃藤時(shí)，選擇一對兼容的雄性和雌性植物至關(guān)重要，以確保成功授粉和最佳的果實(shí)產(chǎn)量。

Fuzzy與Hardy Kiwis的兼容性
模糊獼猴桃（美味獼猴桃）和耐寒獼猴桃（軟毛獼猴桃）是獼猴桃屬中的不同物種，通常不適合授粉。這意味著雄性毛茸茸的獼猴桃不能為雌性耐寒的獼猴桃授粉，反之亦然。在規(guī)劃獼猴桃園時(shí)，重要的是將同一物種的雄性和雌性植物配對，以確保成功的果實(shí)生產(chǎn)。
一些耐寒的獼猴桃品種，如“伊賽”，是自育的，這意味著它們可以在沒有雄性傳粉者的情況下結(jié)出果實(shí)。然而，即使在自交品種中，附近有一株兼容的雄性植物也可以提高產(chǎn)量，改善果實(shí)的大小和質(zhì)量。

獼猴桃的授粉機(jī)制
獼猴桃植物的授粉主要是通過花粉從雄花向雌花的移動(dòng)來實(shí)現(xiàn)的，這一過程被稱為異花授粉。最有效的傳粉者是蜜蜂，它們在花與花之間傳播花粉。風(fēng)也起著作用，盡管與昆蟲授粉相比，由于獼猴桃植物產(chǎn)生的花粉粒相對較重，它的效果較差。
為了最大限度地提高授粉效率，在果園中保持健康的傳粉者群體非常重要。通過在附近種植富含花蜜的花朵來鼓勵(lì)本土蜜蜂和其他授粉昆蟲，可以提高授粉率，從而更好地坐果。
花粉活力和壽命
獼猴桃花粉的活性可能受到多種因素的影響，包括溫度、濕度和花粉的年齡。獼猴桃花粉在新鮮生產(chǎn)時(shí)最具活力，在最佳條件下，它可以存活數(shù)天。然而，長時(shí)間暴露在高溫或非常干燥的條件下會(huì)降低其存活率，導(dǎo)致授粉成功率降低。
為了確保有效的授粉，重要的是要確定雄性和雌性植物的開花期，以便雌花在花粉仍然存活的情況下是可接受的。對于花期較短的品種來說，這個(gè)時(shí)間點(diǎn)尤其關(guān)鍵。
高溫和大風(fēng)條件的影響：
炎熱和多風(fēng)的條件會(huì)進(jìn)一步挑戰(zhàn)花粉的活力和授粉。高溫會(huì)導(dǎo)致花粉更快地降解，降低其有效性，而強(qiáng)風(fēng)會(huì)在物理上取代花粉，使其不太可能到達(dá)雌花。此外，這些惡劣的條件會(huì)為蜜蜂等傳粉者創(chuàng)造不適宜的環(huán)境，減少他們的活動(dòng)，進(jìn)一步限制成功的授粉。這強(qiáng)調(diào)了選擇合適的種植地點(diǎn)和考慮環(huán)境因素以優(yōu)化授粉的重要性。
授粉對果實(shí)品質(zhì)和產(chǎn)量的影響
成功的授粉與獼猴桃的質(zhì)量和產(chǎn)量直接相關(guān)。授粉良好的花朵往往會(huì)結(jié)出更大、更均勻的果實(shí)，味道更好，營養(yǎng)含量更高。相比之下，授粉不良會(huì)導(dǎo)致果實(shí)變小、畸形，甚至落果。
對于商業(yè)種植者來說，實(shí)現(xiàn)一致和徹底的授粉對于最大限度地提高市場產(chǎn)量至關(guān)重要。這不僅涉及選擇合適的品種并確保開花時(shí)間的重疊，還涉及管理果園條件以支持傳粉者活動(dòng)和花粉活力。確保有足夠的庇護(hù)所免受強(qiáng)風(fēng)侵襲，保持最佳的溫度和濕度水平，并提供充足的水源，可以為蜜蜂等傳粉昆蟲創(chuàng)造更有利的環(huán)境。此外，種植吸引傳粉者的開花植物并盡量減少有害農(nóng)藥的使用可以進(jìn)一步提高授粉成功率。
通過修剪和開花木材管理優(yōu)化獼猴桃的生產(chǎn)效率
獼猴桃花生長在一年樹齡的木材上，這種木材是在上一個(gè)季節(jié)生長的，因此這種生長對成功的果實(shí)生產(chǎn)至關(guān)重要。由于獼猴桃藤是充滿活力的種植者，它們每個(gè)季節(jié)都會(huì)產(chǎn)生大量的新木材，但老木材（一年以上）的產(chǎn)量通常會(huì)降低，花朵和果實(shí)也會(huì)減少。為了保持高產(chǎn)，定期修剪葡萄藤是至關(guān)重要的，重點(diǎn)是去除陳舊、無生產(chǎn)力的木材，并鼓勵(lì)新鮮、結(jié)果的嫩芽生長。
這種做法被稱為“甘蔗替代”，涉及在冬季休眠期修剪舊甘蔗，讓新的甘蔗生長并成為即將到來的季節(jié)的主要結(jié)果木。通過不斷用新的生長物替換舊木材，葡萄藤保持活力，每年都能結(jié)出豐碩的果實(shí)。
夏季修剪在保持葡萄藤健康和生產(chǎn)力方面發(fā)揮著同樣重要的作用。通過在生長季節(jié)去除多余的生長，夏季修剪可以改善樹冠內(nèi)的空氣流通和光線穿透，這有助于降低真菌疾病的風(fēng)險(xiǎn)，并確保葡萄藤的所有部分都能獲得足夠的陽光。這不僅有助于高品質(zhì)水果的發(fā)展，也有助于葡萄藤的整體活力，使其更能抵御環(huán)境壓力。
定期、適時(shí)的修剪可確保獼猴桃藤年復(fù)一年地保持高產(chǎn)，在保持健康和活力的同時(shí)，結(jié)出大而美味的果實(shí)。了解和實(shí)施這些做法是成功種植獼猴桃的關(guān)鍵，無論是在商業(yè)果園還是家庭花園。
綜上所述，通過精心選擇兼容的雄性和雌性品種，確保其花期重疊，并保持有利的授粉條件，種植者可以顯著提高獼猴桃的產(chǎn)量和質(zhì)量。此外，定期和戰(zhàn)略性的修剪對于更新果樹和維持長期生產(chǎn)力至關(guān)重要。通過整合這些做法，無論是在商業(yè)果園還是家庭花園，種植者都可以年復(fù)一年地享受豐富而優(yōu)質(zhì)的獼猴桃收成。
