新型植物生长调节剂对烤烟幼苗生长的影响
Effects of New Plant Growth Regulators on Growth and Quality of Tobacco Seedlings
摘要
Abstract
In order to explore the effects of new plant growth regulators on the growth and quality of tobacco seedlings,naked tobacco seeds were soaked with different concentrations of the regulators,and then cultured in the seedling tray, and the regulators were sprayed twice on leaves during the seedling growth stage,with water as the control treatment( CK) . The results showed that the six new regulators had various effects on promoting growth and improving quality of tobacco seedlings with 500 times dilution and 1 000 times dilution. The sugar contents of cinnamamide amide ( 5%) and cinnamamide quaternary ammonium salt ( 5%) treatments with 500 times dilution were higher than that of CK about 3 . 9 , 4 . 0 percentage points. The content of free amino acid of naphthalen dicarboxamide(5%) treatment with 500 times dilution was higher than that of CK 48. 31%. At the same time, treatments of yamanashi amide (5%) and yamanashi quaternary ammonium salt ( 5%) with 500 and 1 000 times dilution, and cinnamamide amide ( 5%) with 500 times dilution could reduce the content of nitrate in tobacco seedlings. By comprehensive analysis, the compounds of naphthalene,cinnamon and yamanashi series all have a strong role in promoting growth and improving quality of the tobacco seedlings.关键词
