摘要/Abstract

摘要： 以小叶蚊母（Distylium buxifolium）丽玫为研究对象,通过测量叶长、叶宽、梗长、叶面积等指标,研究其春季叶质体色素含量变化和叶动态变化。结果表明,春季小叶蚊母丽玫的叶质体色素含量、叶面积、叶色RGB值、叶长、叶宽、枝长等各项数值总体呈增长趋势。小叶蚊母丽玫的叶绿素a和叶绿素b含量增长幅度比类胡萝卜素大,而叶绿素a和叶绿素b含量在4月1日前增长速度缓慢,4月7日开始增长速度大幅提高;小叶蚊母丽玫的叶面积在3月28日到4月1日间增长速度最快,4月7日达到最大值,4月7日后,随着叶片的逐步成熟,叶片开始失水、萎缩,叶面积的增长也不再明显;小叶蚊母丽玫叶色的变化趋势总体是红色和蓝色成分减少,绿色成分增加,表现为小叶蚊母丽玫叶色在春季由紫红逐渐向绿色转变;小枝长度3月15日到4月12日增长缓慢,4月12日之后增长速度变快。小叶蚊母丽玫的叶质体色素含量和各项叶动态数值在3月28日至4月7日之间增长速度最快。

Abstract: Taking Distylium buxifolium named "Li mei" as the research object, selecting the randomly selected 200 strains of the same plant, the trend of plastid pigment content change and dynamic change were studied in the spring by measuring the leaf length, leaf width, stem length, and leaf area index. The results showed that there was a growth trend in the leaf plastid pigment content, leaf area, RGB value, leaf length, leaf width and branch length, et al. The extent increased obviously about varieties "li mei" chlorophyll a and chlorophyll b growth than the carotenoid content, the chlorophyll a and chlorophyll b content growth speed were slow in Apri1 1, but the growth rate were sharply higher from April 7;The growth rate of leaf area varieties of li mei's were the fastest on March 28 to April 1 day, the peak was the largest in April 7. Form April 7, as the blade gradually matured, leaves began to lost water and atrophy, the growth of leaf area was no longer obvious; The variation trend of the variegated leaf color was decreased in red and blue, and the green component increased. It showed that the leaf color of D. buxifolium named "Li mei" was changed from purple to green in spring. Branchlets grew slowly from March 15 to April 12, and grew faster after April 12. The pigment content of leaf plasmid and the dynamic value of the leaves of D. buxifolium named "li mei" rose the fastest between March 28 and April 7.
