1.用大于100 p.p.m.浓度的抗坏血酸溶液处理大豆黄化幼苗(幼苗处理)能促进幼苗子叶转绿。2.大豆黄化幼苗转绿的最适温度是30℃,而AA的作用亦以此温度为最显著。3.大豆黄化幼苗子叶转绿的绝对量随苗龄而增加。4.不同苗长的黄化幼苗转绿时对抗坏血酸的敏感程度不同。较短与较长的幼苗比较敏感,而中等长度的幼苗最不敏感。5.抗坏血酸溶液浸种(种子处理)后,也能使黄化幼苗子叶转绿后叶绿素的含量增加。6.浸种处理时叶绿素a增加的百分数大于叶绿素b增加的百分数。即其a/b值比对照的高。而幼苗处理时,除了中等长度的苗以外叶绿素b增加的百分数却大于叶绿素a增加的百分数。即其a/b值比对照的低。7.照光开始后,子叶中先产生叶绿素a,后产生叶绿素b。
1. Treatment of soybean etiolated seedlings (seedling treatment) with an ascorbic acid solution at a concentration greater than 100 p.p.m. can promote seedling leaf greening. The optimum temperature of greening of soybean yellowing seedlings was 30 ℃, and the effect of AA was the most significant. 3. The absolute amount of cotyledons of soybean yellowing seedlings increased with seedling age. 4. Different seedlings of yellowing seedlings turn green when sensitive to ascorbic acid levels. Shorter and longer seedlings are more sensitive, while medium-sized seedlings are the least sensitive. Ascorbic acid solution soaking seed treatment (seed treatment), but also make the yellow leaves of cotyledons turn green chlorophyll content increased. 6. The percentage of increase in chlorophyll a during soaking treatment is greater than the percentage of increase in chlorophyll b. Ie its a / b value is higher than that of the control. However, the percentage of increase of chlorophyll b except the medium-sized seedlings was larger than the increase of chlorophyll a in seedling treatment. Ie its a / b value is lower than the control. 7. After the start of light, cotyledons in the first produce chlorophyll a, chlorophyll b after.
