摘要: 研究表明:果实中干物质和水分增长基本同步;两品种(系)果皮从最厚开始变薄的转折期,正是全果含水量达80%左右。在雅安气候条件下,华脐果实体积快速增长期在6月中旬~9月上旬,单果重以8月10日~9月10日增加最快(2.06克。果-1、日-1);兴津温州果实体积快速增长期为5月底~8月底,单果重以7月下旬~9月下旬增加最快(1.30~1.40克、果-1、日-1)。两品种(系)果重的增长可持续到成熟,提前采摘将直接影响产量。

Abstract: The result of the study is as follows:The increasing of the dry matter and that of water in the fruits of "Xing Jin" Satsuma (citrus unshiu Tanaka) and navel orange(C. sinensis Osbeck) are basically synchronous. During the turning period from thickness into thinness in peel, the water rate of fruit is jusf about 80%. From the mid of June to early Saptember appears a period in whick the fruit volume of washington navel orange grows quickly under the weather conditions of Ya'an. On Augusf 10 to Saptember 10,the weight increases quickly (2.06g. fruit-1. day-1). The quickest groning period of the fruit votume of Xing Jin Satsuma is from late May folate Augusf. From late July to late saptember, the weight increases quickly (1.30-1.40g. fruit-1. day-1). The increment of weight maintains to maturation for both of the cultivar fruits. Therefore, picking in advance will directly reduce the yield.
