| 摘 要： | 研究了不同浓度钛溶液灌根对烤烟生长过程中各种生理特性的影响.结果表明:在伸根期用适量的钛肥灌根,能增加烤烟叶片中叶绿素、类胡萝卜素含量和转化酶活性,可以促进烤烟的光合作用,有利于烟草同化产物的转化和利用,同时也能够提高烤烟叶片中SOD和POD活性,降低MDA含量,明显降低烟叶中细胞膜脂过氧化程度,提高烤烟抗衰老能力和抗逆性.上述作用,在钛肥灌根的短期内,效果尤为明显,其中富钛增效剂稀释600倍灌根效果最好.

| Abstract: | The effects of titanium added to soil on some physiological property were studied.The results showed that the content of chlorophyll,carotenoid and the invertase activity were increased after irrigating right amount titanium at root elongation stage,titanium could promote photosynthesis in flue-cured tobacco,which also was beneficial for the transformation and utiliation of assimilate.At the same time,titanium could improve the activities of POD and SOD,but reduced MDA contents,thus decreasing the degree of... |
