Study On The Conformation Among Populus×Euramericana Cv. 'Zhonghuahongye' Introductions And Changes Of Physiology And Biochemistry During Its Leaf Colour Transformation

Populus nigra has been played an important intimbering,and also been comprehensive used in this kind of populus,has idiograpHic lives,which could been changed time by time steadily from bourgeon to early summer its branches and lives will expressing mauve,during zhe whole summer, in zhe underside its branches and lives will changing color to green, in zhe autumn its branches and lives will changing orang before defoliation.Populus×euramericana cv. Zhonghuahongye is a kind of colored lives arbor, which has straight bole,expeditious growing, simpleness reproduced, potential is endlessness.Study on conformation among Populus×euramericana cv. Zhonghuahongye Introductions and Changes of PHysiology and Biochemistry during its leafcolour transformation, trying to find out its inhesion rule, redounding to its long-term stage studies.Now the major results studied in this paper are abstracted as follows:(1) Extraction of the preliminary study, the basic components of the red leaves of a preliminary analysis, that leaves the main ingredients for the red pigment anthocyanin, but color the environment,lighting, temperature, soil, pH, the different levels of nutrition and great changes.(2) Its leaves in the red slice of anatomical structures, including paraffin sections and thin slices through the pores, initially identified and I- 63 in Populus×euramericana cv. Zhonghuahongye,I-69 leaves on the structure of the difference, and I-63,I-69 Compared to China and Populus×euramericana cv. Zhonghuahongye chloroplast size reduction,an increase in the number of base-layer tablets pile stacked osteoporosis. Different color period, in Populus×euramericana cv. Zhonghuahongye chloroplast ultrastructure change.when the leaves turn to green, the decrease in the number of chloroplasts, the volume has increased over the particleboard floors of a corresponding reduction.(3) Populus×euramericana cv. Zhonghuahongye in the growing season of pHotosynthesis, and the dynamic changes, the initial proof of the resistance in the red in populus comparative advantage.(4) Populus×euramericana cv. Zhonghuahongye in the red pigment in the leaves major, including chloropHyll and lutein, carotene and nthocyanins, the dynamic changes, including the content and types of dynamic change, preliminary analysis of the color changes in the composition of the various types of pigment, content and the relationship between the ratio of the decision.(5) Using CIE lab L~*a~*b Quantitative determination to text the red color of the leaves quarter of the dynamic changes, the color changes to quantify, identify the color changes in several key period for the future Separation of genes related to lay a foundation.(6) Comparing the content of soluble sugar , flavanone , polyp henol , amino acid in the leaves of Populus×euramericana cv. Zhonghuahongye , analysed relationship of leaves's content and pigment changing.(7) Populus×euramericana cv. Zhonghuahongye in the leaves elements in the change in the relationship with the color changes, including the N, P, K, and other large metal trace elements and the dynamic changes, the color filter out a few changes have significant effect on the ion enriched, Populus×euramericana cv. Zhonghuahongye in the garden of a better used on the effect of laying the theoretical foundation.
