摘要 在柑橘、帝国、埃勒诺和默科特这三个商业品种中检查了花粉源对坐果和果实品质特征的影响（xenia 效应）。每个品种的六棵树接受六种授粉处理：三个异花粉源、自花授粉、套袋和去雄套袋。在所有处理中评估花粉管生长、坐果率、果实重量、种子含量、糖和酸含量。在所有品种中都发现了显着的 xenia 效应，包括对糖含量的影响。 “帝国”被发现是自交不亲和的，因为自体花粉管在上部花柱中受到抑制。这导致自花授粉果实的坐果率较低（P<0.01），果实重量非常低（33-55克，相比之下为92-103克，P<0.01），并且果实含有很少或不含种子。此外，与自花授粉和未授粉处理相比，“Ellenor”和“Murcott”花粉显着提高了果实的糖含量0.9-1.6%（P<0.05）。广泛...
SummaryThe effects of pollen source on fruit set and fruit quality characteristics (xenia effects) were examined in three commercial cultivars of mandarin, Imperial, Ellenor, and Murcott. Six trees of each cultivar received six pollination treatments: three cross-pollen sources, self-pollination, bagging and bagging with emasculation. Pollen tube growth, percentage fruit set, fruit weight, seediness, sugar and acid content were assessed in all treatments. Significant xenia effects, including effects on sugar content, were found in all cultivars. `Imperial' was found to be self-incompatible as self-pollen tubes were inhibited in the upper style. This resulted in a lower fruit set in self-pollinated fruits (P<0.01), a very low fruit weight (33–55 g, compared with 92–103 g, P<0.01), and fruits containing few or no seeds. In addition, `Ellenor' and `Murcott' pollen significantly increased sugar content of fruit by between 0.9–1.6% compared with self-pollinated and unpollinated treatments (P<0.05). Widespread ...
