An investigation was conducted into the relation of ABA (cis-trans-abscisic acid) in the dormant buds of alternate bearing ;Valencia' orange (Citrus sinensis [L.] Osbeck) trees. ABA did not appear to be related to alternate bearing but t-ABA (2-transabscisic acid) did. There was 5- to 10-fold more t-ABA than ABA in the buds. There was more t-ABA in the buds of the "on" trees than in the buds of the "off" trees, and a drastic drop in t-ABA in both types of buds as spring growth approached. Bud dormancy and readiness for growth as related to t-ABA are discussed.
对异花结实的‘瓦伦西亚’甜橙（Citrus sinensis [L.] Osbeck）休眠芽中 ABA（顺式-反式-脱落酸）的关系进行了调查。ABA 似乎与异花结实无关，但 t-ABA（2-反式-脱落酸）有关。芽中 t-ABA 的含量是 ABA 的 5-10 倍。“开”树的芽中 t-ABA 多于“关”树的芽，随着春季生长的临近，两种类型的芽中 t-ABA 急剧下降。讨论了 t-ABA 与芽休眠和生长准备的关系。
