为明确新型植物生长调节剂对烤烟幼苗生长的作用,采用6种新型植物调节剂的500、1000稀释倍液对烤烟种子进行裸种浸种处理,在育苗盘中育苗,并于烤烟幼苗生长期叶施2次,同时以清水处理为对照( CK),研究了6种新型植物调节剂对烤烟幼苗生长及内在品质的影响。结果表明,所用新型植物生长剂500倍液和1000倍液使烤烟幼苗的农艺性状和内在品质均有不同程度的改善和提高。5%肉桂酰胺水剂和5%肉桂酰胺季铵盐的500倍稀释液处理叶片中可溶性糖含量较CK分别提高3.9、4.0个百分点,5%萘酐酰胺水剂的500倍液处理氨基酸含量高于 CK 48.31%,5%山梨酰胺水剂、5%山梨酰胺季铵盐2个稀释倍数处理和5%肉桂酰胺水剂的500倍液处理具有降低烤烟幼苗叶片中硝酸盐含量的作用。综合分析,萘酐系列、肉桂系列及山梨系列化合物的水剂对烤烟幼苗具有较强的促长提质作用。
為明確新型植物生長調節劑對烤煙幼苗生長的作用,採用6種新型植物調節劑的500、1000稀釋倍液對烤煙種子進行裸種浸種處理,在育苗盤中育苗,併于烤煙幼苗生長期葉施2次,同時以清水處理為對照( CK),研究瞭6種新型植物調節劑對烤煙幼苗生長及內在品質的影響。結果錶明,所用新型植物生長劑500倍液和1000倍液使烤煙幼苗的農藝性狀和內在品質均有不同程度的改善和提高。5%肉桂酰胺水劑和5%肉桂酰胺季銨鹽的500倍稀釋液處理葉片中可溶性糖含量較CK分彆提高3.9、4.0箇百分點,5%萘酐酰胺水劑的500倍液處理氨基痠含量高于 CK 48.31%,5%山梨酰胺水劑、5%山梨酰胺季銨鹽2箇稀釋倍數處理和5%肉桂酰胺水劑的500倍液處理具有降低烤煙幼苗葉片中硝痠鹽含量的作用。綜閤分析,萘酐繫列、肉桂繫列及山梨繫列化閤物的水劑對烤煙幼苗具有較彊的促長提質作用。

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.
