摘要:
利用外源激素对番茄等侧枝生长较为旺盛的作物株型进行调控是现代农业高效生产的保证。为明确萘乙酸(NAA)和6-苄氨基嘌呤(6-BA)对番茄株型的调控机制,本研究以侧枝稀疏型番茄品种NT823和侧枝茂盛型番茄品种NT68为材料,分别进行不同浓度和次数的外源NAA和6-BA处理,分析其对番茄侧枝生长和植株形态的影响。结果表明,NAA和6-BA的施用浓度和次数均对番茄侧枝生长和植株形态有显著影响。53.7 μmol/L NAA能显著抑制NT68番茄侧枝生长,而400.0 μmol/L 6-BA则能显著促进NT823番茄侧枝生长。3～4次NAA处理能有效抑制番茄侧枝并促进株高、茎粗生长；1次6-BA处理对侧枝数量的促进作用最大,3～4次6-BA处理最有利于侧枝伸长和茎粗发育,但亦显著抑制株高生长。 NT823对NAA和6-BA的敏感性高于NT68,高节位侧枝长度对NAA和6-BA的敏感性高于低节位侧枝。本研究结果为合理利用外源激素NAA和6-BA进行番茄植株的定向调控提供了依据。
Abstract:
The use of exogenous hormones to regulate the plant type of tomato and other crops with strong lateral branch growth is the guarantee of modern high-efficiency agricultural production. In order to clarify the regulatory mechanism of naphthylacetic acid (NAA) and 6-benzylaminopurine (6-BA) on tomato plant type, the effects of exogenous NAA and 6-BA at different concentrations and application frequencies on tomato lateral branch growth and plant morphology were analyzed by using sparse-lateral-branch tomato variety NT823 and lush-lateral-branch tomato variety NT68 as materials. The results showed that the application concentration and frequency of NAA and 6-BA had significant effects on the lateral branch growth and plant morphology of tomato. 53.7 μmol/L NAA significantly inhibited the lateral branch growth of NT68 tomato, while 400.0 μmol/L 6-BA significantly promoted the lateral branch growth of NT823 tomato. Three to four applications of NAA could effectively inhibit tomato lateral branch growth and promote plant height and stem diameter. One application of 6-BA had the greatest promoting effect on the number of lateral branches, and three to four applications of 6-BA was most conducive to the elongation of lateral branches and the development of stem diameter, but also significantly inhibited the growth of plant height. The sensitivity of NT823 to NAA and 6-BA was higher than that of NT68, and the sensitivity of high-node lateral branch length to NAA and 6-BA was higher than that of low-node lateral branch length. The results of this study provide a basis for the targeted regulation of tomato plants through the rational application of exogenous hormones NAA and 6-BA.
