| 摘 要： | 2002-2003年在江苏高肥力棉田,移栽条件下对9个Bt基因棉花品种(系)的生长发育特点及其碳氮代谢特征进行了研究。结果表明,中棉所29等3个杂交种在整个生长期表现为棉株高增长快,叶面积增长量大,现蕾和成铃强度大,生殖器官干物重也高,叶片全氮、可溶性糖含量高,NR、GPT、Rubisco、Sucroase活性高,表现为生长发育两旺,常规Bt棉GK19和新棉33B盛花前株高、叶面积生长快,现蕾强度大,叶片全氮含量高、NR、GPT活性高,表现为前期生长旺盛;新洋822和苏抗103结铃盛期后叶面积生长快,现蕾和成铃强度大,碳氮代谢强,表现为后期生育旺盛;sGK321和鲁棉研16整个生育期氮代谢强度大,但可溶性糖含量低、Rubisco、Sucroase等活性小,营养生长快,生殖生长弱,表现为营养生长过旺。

| Abstract: | The growth and development and their metabolism of carbohydrate and nitrogen of 9 Bacillus thuringiensis(Bt) transgenic cotton cultivars in transplanting pattern, during the 2002 and 2003 growing seasons at the Yangzhou University Farm, Yangzhou of Jiangsu Province, China. The results showed that Bt transgenic hybrid cotton (CCRI 29, Lumian 15 and Kemian 1) had bigger growth rate of plant height, LAI, squares, boll and dry matter weight of the vegetative and reproductive organs, higher content of leaf total nitrogen, amino acid, soluble sugar and higher enzyme activity of NR, GPT, Rubisco and Sucroase in whole growth period. They had characteristics of both strong vegetative and reproductive growth in whole growth period; The cultivars of GK19 and Xin 33B had bigger growth rate of plant height, LAI, squares, higher content of leaf total nitrogen, amino acid and higher enzyme activity of NR, GPT before peak flower period. They had characteristics of both strong vegetative and reproductive growth before peak flower period; the cultivars (Xinyang 822 and Sukang 103) had bigger growth rate of plant height, LAI, squares, boll and dry matter weight of the vegetative and reproductive organs; higher content of leaf total nitrogen, amino acid, soluble sugar and higher enzyme activity of NR, GPT, Rubisco and Sucroase after peak boll period. They had characteristics of both strong vegetative and reproductive growth after peak boll period. The cultivars of sGK321 and Lumian 16 had bigger growth rate of plant height, LAI, lower development rate of square and boll, higher content of leaf total nitrogen, amino acid and enzyme activity of NR, GPT, lower leaf soluble sugar content, Rubisco and Sucroase activity in whole growth period. They had characteristics of excessive vegetative growth. |
