猕猴桃喷雾授粉的成功与否在很大程度上取决于花粉在水悬浮液中以及在开放花柱头上喷雾液滴干燥过程中的活力。一种由钙、硼和羧甲基纤维素组成的培养基（称为CBC）添加了金合木，使花粉在悬浮状态下保持了3小时的活力，当花粉在25°C和60% RH的滤纸上干燥1小时时，花粉的萌发不受培养基pH的影响，但在pH低于5.0时，花粉管的生长受到抑制。早花雄蕊无性系的花粉可以直接悬浮在cbc -金合欢培养基中，前提是培养基制备用水不含抑制离子。有活力的花粉悬浮在CBC +金合木或CBC +季戊四醇中，喷洒在受花上，增加了每果的种子数。对于两种培养基，增加果实大小所需的最低花粉浓度为每升0.5 g花粉。
Abstract Successful spray pollination of kiwifruit depends largely on maintaining pollen viability in aqueous suspensions and during drying of spray droplets on stigmas of open flowers. A medium composed of calcium, boron, and carboxymethyl cellulose (designated as CBC) with added gum acacia maintained pollen viability for up to 3 h in suspension and gave partial protection when pollen was dried on filter paper at 25°C and 60% RH for 1 h. Pollen germination was not influenced by medium pH but pollen tube growth was inhibited below pH 5.0. Pollen from early flowering staminate clones could be suspended directly in the CBC-gum acacia medium without prior pollen hydration provided that the water used for medium preparation was free of inhibitory ions. Viable pollen suspended in CBC plus gum acacia or in CBC plus pentaerythritol and sprayed on to receptive flowers, increased seed numbers per fruit. For either medium, the minimum pollen concentration needed to increase fruit size was 0.5 g of pollen per litre.
