激素类化合物对番茄幼苗生长及干物质积累的影响

Effects of Hormone Compounds on Seed Germination and Dry Matter Accumulation of Tomato

应用不同浓度的赤霉素(GA3)、吲哚乙酸(IAA)、萘乙酸(NAA)、6-苄氨基腺嘌呤(6-BA)对番茄幼苗进行浸根处理,研究各植物激素处理对番茄干物质积累的影响。结果表明:IAA(0.1 mg/L)、GA3(1 mg/L)、NAA(0.005 mg/L)、6-BA(0.01 mg/L)对番茄幼苗的生长及干物质的积累具有促进作用,同时有利于侧根的生长和根数的增加,并与对照呈显著差异。

The effects of hormone compounds on the dry matter accumulation were studied under the tomato seeds were soaked in different concentrations of Gibberellin （ GA3 ） , Indole-3-acetic acid （ IAA）, 1-naphthyla- cetic acid （ NAA）, 6-benzylaminopurine （ 6-BA ） solution. The results show that, IAA （ 0. 1 mg/L ）, GA3 （1 rag/L）,NAA（O. 005 mg/L）,6-BA（0.01 mg/L） have a significant role in promoting the seedling growth and dry matter accumulation, also increase the number of lateral roots and root growth, and there is a significant difference with ck.
