摘　　要：通过设立试验地,采用标准株法,对常山胡柚不同方位的果实进行了生长发育规律研究。结果表明,常山胡柚果实在生长发育过程中,其大小的变化规律是随着生长发育时间的延长而不断增长,其中有两个明显的增长快速期,分别处于7月的中上旬和9月的中上旬;其单果质量的变化规律也是随着生长发育时间的延长而不断增长,但是,它与果实大小的增长正好相错。果实纵径与横径的变化规律非常一致,只是横径的增长速度明显快于纵径的增长速度,进而引起果形指数总体呈下降趋势。不同方位的果实,在生长发育过程中的变化速度是不同的,经方差分析表明,果实的纵径与横径,在不同的方位之间、在不同的生长发育时期差异极显著;而果形指数、果实质量的变化,在不同方位之间差异不显著,但在不同的生长发育时期差异显著。Standard individual trees were selected from a trial plot, and the growth and development rhythm of fruits on 4 aspects of the trees was studied. The results showed that the fruit size increased with time to come, which had two peaks in the first half of July and same term of September, so did the fruit weight, but the increase terms of fruit weight interleave with that of fruit size. The rhythm of the horizontal diameter of the fruit change was accordant with the longitudinal, but the former increasing was markedly faster than the latter, which led to decrease in the indexes of fruit shape as the whole. The indexes of fruit shape and fruit weights in different directions didn＇t exist significantly difference, except bulk.
