报道了Ｓ－３３０７和ＰＰ３３３对水稻秧苗促蘖效应的比较测定及其与植物内源激素关系的研究结果：（１）用４０μｇ／ｍＬＳ－３３０７和４００μｇ／ｍＬＰＰ３３３进行浸种处理的秧苗，在三叶一心期分别有６５．０１％和１９．７９％的植株出现分蘖，对照秧苗无分蘖出现，Ｓ－３３０７和ＰＰ３３３对水稻均有促蘖效应，而前者的促蘖效应大于后者。（２）经Ｓ－３３０７和ＰＰ３３３处理的秧苗以及对照秧苗，在三叶一心期的苗体内，每克鲜重ＣＴＫ含量分别为１３４６．４，８４２．４，８６．４ｐｍｏｌ／ｇ；ＣＴＫ／ＩＡＡ的比例分别为３．６９，２．５４，０．２９。在同期测定了秧苗体内可溶性糖、淀粉和全糖以及可溶性氮、蛋白质和全氮含量，它们在三种处理苗体内无明显差异。（３）本试验结果表明：Ｓ－３３０７对水稻的促蘖效应大于ＰＰ３３３，Ｓ－３３０７和ＰＰ３３３的促蘖效应与其提高水稻秧苗体内ＣＴＫ含量和ＣＴＫ／ＩＡＡ比例密切相关，其中Ｓ－３３０７提高ＣＴＫ含量和ＣＴＫ／ＩＡＡ比例的作用大于ＰＰ３３３，这一点与Ｓ－３３０７的促蘖效应大于ＰＰ３３３的结果是相吻合的。
The effects of S-3307 and PP333 on the tillering effect of rice seedlings and their relationship with plant hormones were reported. (1) Seedlings of seed soaking with 40μg / mL S-3307 and 400μg / mL PP333 One-year plants had tillers at 65.01% and 19.79% respectively, and no tillers appeared in the control seedlings. Both S-3307 and PP333 had a tillering effect on rice, while the former had greater effects on tillering. (2) The seedlings treated with S-3307 and PP333 and the control seedlings had the CTK contents of 1346.4,842.4 and 86.4pmol / g per gram in the seedlings of clover and one-heart stage, respectively. CTK / IAA The proportion is 3.69,2.54,0.29. In the same period, the content of soluble sugar, starch and total sugar, soluble nitrogen, protein and total nitrogen in seedlings were determined. There was no significant difference among the three treatments. (3) The results of this experiment showed that the tillering effect of S-3307 on rice was greater than that of PP333. The tillering effect of S-3307 and PP333 was closely related to the CTK content and CTK / IAA ratio of rice seedlings. S-3307 increased CTK The content of CTK / IAA was higher than that of PP333, which was in good agreement with the result that the tillering effect of S-3307 was greater than that of PP333.
