摘要
研究了不同遮阳处理对不同生育期及不同部位烟叶叶绿素及类胡萝卜素的含量影响。结果表明,随着遮阳度的增加,叶绿素含量和类胡萝卜素的含量有增加的趋势。大田生育前期,由于90%遮阳处理极大的降低了光照的有效利用率,作物生长迟缓,其色素含量相对较低,生长后期均为90%遮阳>60%遮阳>CK的变化趋势;不同部位烟叶的色素含量比较可以看出,除现蕾期的下部叶表现为60%遮阳>90%遮阳>CK,其它生育期各部位烟叶色素含量均表现为90%遮阳处理最高,CK处理最低的变化规律。
Effects of different sun-shading treatments plastid pigment on flue-cured tobacco were researched. The results showed that carotenoid and chlorophyll increased with the increase of sun-shading. But the treatment of 90% sun-shading decreased availability of light, the crops grew slowly, content of plastid pigment was lower. At late growth stage, the change was 90%〉60%〉CK. At squaring period, the content of plastid pigment was 60%〉90%〉CK with different position on tobacco top leaf. But at the other growing stages, the regular was 90%〉60%〉CK on different tobacco leaves.
