摘要

目的是研究生长调节剂（ANA+GA3）在“Gefner”atemoya中应用佐剂和人工授粉的有效性。这个实验是在佛罗里达热带研究和教育中心的实验果园里进行的。实验设计采用随机区组，14次处理，10次重复，每个小区3朵花。人工授粉HP和450 NAA+1250 GA3 mg L-1+佐剂和HP的固定果率最高。“Gefner”atemoya树的人工授粉被证明是迄今为止最有效的方法。在没有人工授粉的情况下应用生长调节剂可以产生单性结实的果实，但流产率高，果实小。生长调节剂与人工授粉一起产生小而不均匀的果实，并导致果实的可滴定酸度降低。佐剂的使用对水果的固定性和毒性较低，不推荐使用。

Artificial pollination and use of growth regulators in atemoya ‘Gefner’ fruits

The objective was to study the effectiveness of the growth regulator (ANA + GA3) associated or not to the application of adjuvant and artificial pollination in ‘Gefner’ atemoya. The experiment was conducted in the experimental orchard at Florida’s Tropical Research and Education Center. The experimental design was in a randomized block, with 14 treatments, 10 repetitions and 3 flowers per plot. The highest percentages of fixed fruits were obtained with hand pollination – HP and 450 NAA + 1250 GA3 mg L-1 + adjuvant and HP. The use of hand pollination for ‘Gefner’ atemoya tree proved to be the most efficient method so far. Applying growth regulator without artificial pollination produces parthenocarpic fruits, however with high rate of abortions, and small fruits. Growth regulators together with hand pollination produces small and uneven fruits, and cause reduction in the fruits’ titratable acidity. The use of adjuvant caused low fixation and toxicity to fruits, and its use is not recommended.
