本文就植物生长调节剂在日本梨上应用的现状及今后若干问题作一叙述。促进花芽形成用难以形成花芽的新水梨作试材,在新梢基部7—8片叶处剪截,用植物生长调节剂涂抹切口,调查各种药剂对其花芽形成的影响。结果表明:单用GA_3或GA_(4+7),使枝条伸长,花芽的形成受到抑制;而分别用ⅠAA(吲哚乙酸)、BA(6—苄基腺嘌呤)或B_0和乙烯利处理则可促进花芽形成,其效果后者胜于前者。这些药剂混用的效果就更好。已明确,在花芽分化期之前的6月
In this paper, the status quo of plant growth regulators applied on Japanese pear and some problems in the future are described. Promote the formation of flower buds Difficult to form flower buds of new pear as a test material, in the shoots at the base 7-8 leaves cut off, with plant growth regulator smear incision to investigate the effects of various agents on the flower bud formation. The results showed that the growth of shoots and the formation of floral buds were inhibited by using GA_3 or GA_ (4 + 7) alone, while the treatment with ⅠAA (indole acetic acid), BA (6-benzyladenine) or B_0 and ethephon You can promote flower bud formation, the latter is better than the former. The effect of these agents mix better. It is clear that in June before flower bud differentiation
