摘要
日本紫花牵牛（Ｐｈａｒｂｉｌｉｓｎｉｌｃｖ．Ｖｉｏｌｅｔ）子叶完全展开后，短日照诱导前、诱导后和两个短日照间的长日照处理对植株的花芽分化都有一定的抑制作用。双向凝胶电泳分析表明，长日照处理的牵牛子叶内存在着短日照处理子叶内没有的两种蛋白质（ｐＩ４．１，ＭＷ１６．５ｋＤ；ｐＩ４．２，ＭＷ１６．５ｋＤ）。这些蛋白质可能与长日照抑制牵牛植株的花芽分化有一定关系。
The effect of various long-day treatments on the flowering and cotyledon proteins of Pharbitis nil was studied in this paper. The results indicated that the flowering of Pharbitis nil was inhibited with different long-day treatments and that these proteins of which molecular weights were 16. 5kD(pI4. 1), 16. 5kD(pI4. 2) repectively existed in the cotyledons with long-day treatments disappeared in the ones treated with short-days according to the 2 SDS-PAGE profile. This implied that these proteins might be related to inhibiting the flower bud evocation of Pharbitis nil.
