Effect of Paclobutrazol on Growth and Physiological Characteristics of Tobacco in Floating Seedling System
摘要
Abstract
In the conditions of floating seedling system, this paper studied the seedling quality changes of tobacco with spraying paclobutrazol in the period of three and a primary leaves in South Anhui. The results showed that: (1) Spraying paclobutrazol had significant affection on the agronomic traits, root activity, chlorophyll content, NR activity, matters of anti-adversity and MDA content of tobacco seedlings, the effect was related to different concentration. (2) Compared with CK, after sprayed paclobutrazol with 100 mg/kg and 125 mg/kg, the height of stem decreased by 45.25％ and 52.94％, the dry weight of stem and leaf decreased by 37.02％ and 39.45％, the diameter increased by 19.42％ and 27.30％, dry weight of root increased by 19.53％ and 28.62％, root activity increased by10.59％ and 14.32％, the SPAD content of chlorophyll increased by 18.12％ and 27.68％, the NR activity increased by 54.51％ and 73. 17％, the soluble sugar content increased by 24. 66％ and 40. 54％, the soluble protein content increased by 24. 26％ and 28. 82％, the free proline content increased by 8. 47％ and 10. 77％, the MDA content decreased by 7.54％ and 8.70％, seedling characteristics was improved and the effect was better.关键词
