The changes took place in the chloroplast structural degeneration in the course of the mutant leaf color turning from green to white. At the early stage of the albescent process, numerous osmiophilic globules appeared, grana arrangement in the mutant chloroplast became disorder, and the numberof stacks in each granum changed......abnormally increased or decreased, andthylakoid in the grana became swelled. At the middle stage of the albescent process, some cavities could be observed in the chloroplast,...

The changes took place in the chloroplast structural degeneration in the course of the mutant leaf color turning from green to white. At the early stage of the albescent process, numerous osmiophilic globules appeared, grana arrangement in the mutant chloroplast became disorder, and the numberof stacks in each granum changed......abnormally increased or decreased, andthylakoid in the grana became swelled. At the middle stage of the albescent process, some cavities could be observed in the chloroplast, and the interior structure of the chloroplast was gradually decomposed. At the white leaf stage, the whole structure of the cholorplast changed to a vesicle with low electronic density. However, it was found that these alternations could be reverse in the process of the white leaves turning into the green ones. And the interior structure reappeared, grana formed rapidly and arranged in order, and the whole structure of chloroplast renewed normally. Meanwhile, some changes in the interior structure such as the central sap vesicle in the leaf cells took place during the albescent stage.

在返白系小麦叶色由绿变白的过程中,叶绿体结构发生退化。返白初期,出现大量的嗜饿小滴,基粒排列混乱,垛叠层数异常增多或减少,并且发现类囊体有肿大量的嗜胀现象,粒消失。返白中期,叶绿体中呈现空化现象,内部结构逐渐解体。到叶片继而,基全白时期,整个叶绿体变为低电子密度的囊泡状结构。在叶片由自复绿的过程中,叶绿体的这些变化又可逆转,内部结构又重现,基粒迅速形成,排列也较规则,整个叶绿体结构很快恢复正常。在整个返白阶段中,叶细胞中的其它内部结构如中央大液泡等也发生了一定的变化。

The density and ultrastructure of grana in rice chloroplast of differently colored leaves due to different nitrogen supply was studied with electron microscope and high resolution computer image analysis system. Standard Rice Leaf Color Scale was used for the grading of leaf color.

水稻叶绿体计算机图象分析表明,随着叶片色级的提高,叶绿体表面积密度、体积密度以及两者的比值都相应增加。深色稻叶基粒堆直径与高度、类囊体垛叠数与类囊体厚度、叶绿素与类胡萝卜素含量、气孔导度与净光合率均大于浅色叶片。深色叶片基粒堆密集,有些基粒类囊体出现沿叶绿体长轴方向排列整齐现象;浅色叶片基粒堆稀疏,其中较大的基粒类囊体与长轴呈倾斜排列。

In the period of 1994~1997, by using method of spectrophotometer(method of spectrology), we carried out physiological data measurement for photosynthesized pigmentum and flower pigmentum content of leaves themselves of 8 varieties of color leaf tree in growth seasons, drew curves for changing of photosynthesized pigment content along with the time changes and in this we have found the internal reason of the leaf color changings in different seasons.

In the period of 1994~1997, by using method of spectrophotometer(method of spectrology), we carried out physiological data measurement for photosynthesized pigmentum and flower pigmentum content of leaves themselves of 8 varieties of color leaf tree in growth seasons, drew curves for changing of photosynthesized pigment content along with the time changes and in this we have found the internal reason of the leaf color changings in different seasons. It is because of the relationship between content of photosynthesized pigentum and the ambient temperature, the variations of external factors, including the intensity of sunlight, and length of sunshine lead to a color changing in leaves.

1994~1997年我们应用分光光度计法(光谱分析法),对引进的8种色叶树在生长季节叶片自身的光合色素及花色素含量生理指标测定,绘制光合色素含量随时间变化曲线,从而找到了不同季节叶色变化的成因(内因)。由于光合色素含量与温度的关系,光照度的强弱,日照时间的长短等外部因素变化导致色叶树色深浅的变化
