向光性

There was little change of IAA on both sides of the coleoptile which was treated with phototropic stimulation.

向光性刺激后，胚芽鞘向光侧和背光侧生长素的含量没有出现明显的差异。3。

Practically all photobiological behavior of plants and animals-photosynthesis, phototropism, phototaxis,photoperiodism, and vision-utilize this range of radiation.

事实上，所有动植物的光生物行为——光合作用、向光性、趋光性、光周期和视觉——都利用这一辐射范围的能量。

They are involved in phototropism, and in PHOTOPERIODISM, where they are thought to affect phytochrome by transferring light energy from blue to red wavelengths.

它与向光性和光周期有关，一般认为黄素通过把光能从蓝光转移到红光而影响光敏色素。

The detection, absorption, and use of light, as for vision in animals or phototropism and photosynthesis in plants.

光感应对光的感觉、吸收和利用，如对动物的视野和植物的向光性和光合作用

It suggested that the blue light receptor might be the photoreceptor for the negative phototropism in rice root.

推测稻根负向光性的光受体可能为蓝光受体。

Characterizing plant phototropism, the algorithm looks the feasible region of integer programming as plant growth environment, and determines the growth probability on different growth points according to the changes of the object function.

该算法从植物的向光性特点出发，将整数规划的可行域作为植物的生长环境，根据各可行解目标函数的变化情况确定植物的生长信息，进而模拟出向光源迅速生长的植物生长动力学模型。

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.

为了研究水稻根负向光性的光受体，观察了光质对稻根的负向光性效应，用紫外－可见分光光度计测定了水稻根冠浸提液的吸收光谱，并对根冠中的蛋白质进行了SDS-PAGE电泳分析。

The known photoreceptors for UV - A/blue light are eryptochrome 1 and CRY 2, and the phototropism photorecep- tor, phototropin.

已知的蓝光／UV-A受体有隐花色素CRY1和CRY2，向光性受体有趋光素。

The R effect on time-dependent phototropism was further studied by characterizing its fluence-response relationship. The results showed the R effect was a low-fluence-response, unlike those on pulse-induced phototropisms that show a very-low-fluence-response mode.

本研究进一步分析了红光对蓝光照射时间依赖型向光性影响的光量反应曲线，发现该反应不像红光对脉冲蓝光诱导的向光性的影响那样属于超低光量反应，而是一种低光量反应，且之后的脉冲远红光可以逆转红光对TDP影响的效果。

Root,immunoassay of ELISA(enzyme linked immunosorbent assay) was employed to determine IAA concentration in root tip, unilateral application of agar block containing IAA on root tip was carried out to investigate the effect of exogenous IAA on phototropic response.

为了研究生长素在水稻根负向光性反应中的作用，用含有IAA的琼脂块贴附在种子根的根尖表面观测IAA对根的生长效应，用ELISA法测定根尖的IAA含量，并对种子根弯曲部分进行半薄切片，结果表明：(1)种子根的生长方向既受光的调控也受外施的IAA的调控，根尖向贴有含IAA琼脂块的一侧弯曲生长；(2 )不定根在光照 1.5h后，背光侧的IAA含量明显大于向光侧；(3)种子根尖发生弯曲生长是伸长区的细胞不均等生长所致。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。
