In the process of root cutting, the root accumulated a lot of soluble sugar and soluble protein, which provided material and energy for the cell differentiation. As root differentiating, soluable protein was continuously used up. During 10 to 20 days, the content of soluble sugar and soluble protein in the basipetal top and end of rootkept comparatively stable, then declined as adventitious buds and roots growing. 40 days later, they kept invariable, because the newly formed bud can photosynthesize and the newly formed root can absorb nutrient from outside. The dynamic balances of endogenous hormone regulate adventitious buds and roots of the root. During callus growing and adventitious bud differentiating.

上部根段在细胞分化前期积累了大量的可溶性糖，为后期的分化提供能源物质，同时积累了大量的可溶性蛋白质，为愈伤组织的产生提供能源，而后随着分化，可溶性蛋白质不断被消耗。10～20d根段上部及下部的可溶性糖、可溶性蛋白质含量保持在相对稳定的水平变化不大，后期随着不定芽及不定根的生长下降较快。40d后，新形成的芽已经能够进行光合作用，新形成的根也可从外界吸收营养物质，可溶性糖、可溶性蛋白质含量基本保持不变。

It influences the spike length, the diameter of stalk and ear-corn; influences seed weight, the weight of seeds per ear, ear-corn, bracteal leaf, ear axis; the number of seeds per ear and per line, line number, the volume and weight of 100 seeds, and the seed density. Enhanced UV-B radiation also effects accumulation of dry matter with different influence in different growing period and different organ.

对玉米生长动态的影响包括干物质生产速率减小，且生育期不同玉米干物质积累所受到的影响也不同，同一个生育期不同UV-B处理下玉米不同器官所受到的影响程度不同。

Copper content and accumulation in shoots of both two Elsholtzia species decreased with increasing Zn regardless of Cu supply. However, Zn concentration in E. splendens were increased by Cu supply at low or high Cu level, and in E. argyi Zn contents were also increased by Cu supply at 0.5 and 50μmol L〓.

研究结果表明，50μmolL〓的Cu有利于海州香薷根系的生长，但却明显抑制紫花香薷地上部分的干物质产量，Zn处理浓度直到200μmol L〓也未见两种香薷的干物质产量的下降。

Bamboo first crystallizes then lignifies during bamboo shoot growth and basically forms crystal structure in one month. 1-year-old bamboo culm ends growth and its height,thickness, volume almost change little, but culm tissue is small and tender and there is more water and less substance in it. Bamboo crystal proportion keeps invariable during this period.2-year-old bamboo culm begin to lignify,its cellulose proportion debases and its crystal proportion decreases. Bamboo lignin debases, crystal proportion changes a little in the end of this period.Many-old-year bamboo culm crystal proportion is almost invariable. Freaky bamboo cell wall crystal region's thickness is less than normal bamboo's. Bamboo cross section crystal area and the ratio of long axis to short axis are less than normal bamboo's,and roundness,irregular index, the fiber cap density per unit area increase more than normal bamboo's.

竹笋生长阶段是先结晶后木素化的过程，一个月内细胞壁结晶组织基本形成；2）一年生竹材的植株秆茎生长结束，秆茎的高度、粗度和体积变化不大，但秆茎的组织幼嫩，含水量高，干物质少，竹材结晶度基本不变；3）二年生竹材的植株开始木质化，纤维素比例降低，结晶度减少，到后期竹子木质化降低，竹材结晶度变化不大；4）多年生竹材的结晶度没有太大的变化，结晶度大小处于波动状态；5）畸形竹材纤维帽细胞壁结晶区的厚度比正常竹小，其横截面结晶区的面积、纤维帽长轴与短轴比有所减少，而圆形度、异型指数有所加大，单位面积纤维帽的密度增大。

By spraying polyamines synthesis inhibitors, D-Arg, MGBG (Methylglyoxal bis-guanylhydrazone) and CHA at various concentrations to panicles and flag leaves of indica rice Jinlingxiangnuo (a higher polyamine rice variety) at heading, flowering and grain filling stages, changes in contents and components of PAs in rice grains after harvest were investigated.
