The results showed that compared with soil culture, the root cap was not obvious with less amyloplast and polysaccharose substance under water culture. The root epidermis under water culture was thinner than that of soil culture, with little root hair or not, in which cortex parenchyma tissue developed with big cell, solution proliferative aerenchyma in intercellular space, and thin cell wall. However, the root cap under soil culture was big, with strong PAS reaction and no aerenchyma tissue.

To properly explore the photoreceptor for the negative phototropism in rice (Oryza sativa L.) root, lights with different wavelengths were applied to investigate the effect of light quality on phototropic response. The negative phototropic bending could be induced prominently by blue/UV light, while not be induced by red and far-red light.

本研究從植株整體的物理性質（源匯強度和韌皮部傳輸性質）出發(fā)www.xxxxx，從更低的層次上模擬觀察到了在環(huán)境水分條件發(fā)生變化時植株根冠間存在的功能平衡現(xiàn)象，并對此作出了機理性的解釋，說明了當同化物的傳輸受維管束中壓力勢控制99久久99久久精品免费看子伦，而且韌皮部與所在器官的水勢保持平衡狀態(tài)時美女视频黄a免费久久，根冠之間就會存在功能平衡關系，這說明了根冠間的功能平衡現(xiàn)象應該是維管植物適應環(huán)境變化過程中的一種普遍現(xiàn)象18禁止爆乳无遮挡污污污网站。

The primary result reveals that the normal expression of Clone C103 is profoundly regulated by endogenous auxin in maize root tip, and the expression of Clone C103 maybe has some relationship with statolith in the periphery of central cap.

由此表明玉米根尖內源生長素影響根冠特定基因Clone C103的正常表達国模人体艺术大胆私拍套图；Clone C103在根冠的表達位置推測該基因正常表達可能與中心根冠外周的平衡石有關。

The sucrose content of the low R/S line "NAU-LR-04" was higher than those of three highR/S lines at all stages, while the fructose content was lower in "NAU-LR-04". Changes ofactivities of sucrose synthase were similar to sink activities in all the lines, and theactivity of SuSy in low R/S line is higher than those of high R/S lines.

The promeristem is consisted of three groups of initial cells, which have typical cytological characteristics of meristem cells. The primary meristem is composed of calyptrogens, primordial epidermises, periblems and pleromes. Both the calyptrogens and the primordial epidermises initiate from the same layer of initial cells.
