从幼果生理活性物质消长方面对蕉柑少籽原因进行分析．结果表明：（１）内源生长调节物相对含量、多胺总量和精胺（Ｓｐｍ）水平与胚珠败育有关，内源吲哚乙酸（ＩＡＡ）、脱落酸（ＡＢＡ）含量，ＡＢＡ／ＩＡＡ比值，腐胺（Ｐｕｔ）、亚精胺（Ｓｐｄ）水平均与胚珠败育及珠心胚的发生发育有一定联系，它们的曲线都在胚珠败育或珠心胚发生的关键时刻出现折点，尤其是ＡＢＡ／ＩＡＡ比值变化最为突出，说明激素间的平衡对调控胚珠发育起了重要作用；（２）内源生长调节物除ＩＡＡ、ＡＢＡ外，还要注意酚类物质和ＧＡ的作用；（３）ＩＡＡ含量受过氧化物酶（ＰＯＤ）和吲哚乙酸氧化酶活性影响少，而基本上和总酚含量呈负相关．
Analysis of the causes of fewer banana citrus fruits from the growth and decline of physiologically active substances in young fruit. The results showed that: (1) The relative contents of endogenous growth regulators, total polyamines and spermidine (Spm) were related to the abortion of ovules. The content of endogenous IAA, ABA, ABA / IAA (Put), spermidine (Spd) levels were related to the development of ovule abortion and rosette embryos, and their curves were all at the critical moment of ovule abortion or rosette embryogenesis , Especially the ratio of ABA / IAA was the most prominent, indicating that the balance between hormones played an important role in the regulation of ovule development. (2) In addition to IAA and ABA, endogenous growth regulators should also pay attention to the role of phenols and GA; (3) IAA content was less affected by peroxidase (POD) and indoleacetic acid oxidase activity, but negatively correlated with total phenolic content.
