博德特氏菌HN36对二氯喹啉酸胁迫下烤烟的修复效应
Repaired Effects of Bordetella HN36 on Flue-cured Tobacco Stressed by Quinclorac
摘要
Abstract
In order to alleviate quinclorac's harmfulness on flue-tobacco, repaired effects of the quinclorac degrading bacteria HN36 on plant height,leaf length and width,fresh and dry weight, cellulose activity,and content of amino acids of tobacco stressed by quinclorac were studied according to a pot experiment. The results indicated that HN36 could relieve the inhibition of the plant height,leaf length and leaf width,and decrease the cellulase activity and the content of ami-no acids of tobacco leaf. As the concentration of HN36 in soil increased,the repaired effect became better and better. In contrast to tobacco damaged by quinclorac,at 30 days after transplanting,bythe treatment of 3 X 1010 HN36 cells per kilogram of dry soil, the plant height, leaf length and width of tobacco increased 63. 46%, 56. 51% and 95. 07% , respectively; the fresh weight and dry weight of overground parts of tobacco increased 47. 24% and 17. 65% while underground parts increased 105. 60% and 136. 84%; the cellulose activity and the content of amino acids of tobacco leaf decreased 46. 39% and 35. 46%. The residual quinclorac in soil treated by 3X1010 HN36 cells per kilogram of dry soil could not cause harm to tobacco at 30 days after transplanting. In the treatment of 3 X 1010 and 3 X 109 HN36 cells HN36 per kilogram of dry soil, the residual quinclorac in soil even could not be detected at 60 days after transplanting. In general,among repaired effects of HN36 on flue-cured tobacco and soil which were stressed by quinclorac,3X 1010 HN36 cells per kilogram of dry soil was the best .followed by 3X109 and 3X108.关键词
