查询词典 stylar

The degradation of pollen tube RNA in vitro by stylar S-RNase at different temperatures was performed to detect the extent of degradation using the agarose gel electrophoresis. The germination and tube growth of self-pollen and the RNA of self-pollen tube were inhibited and degraded significantly greater than cross-pollen respectively at 10℃ and 25℃, but no significant difference when the temperature rose to 35℃.

10℃、25℃时，花柱S-RNase抑制自花花粉萌发和花粉管生长的程度极显著大于抑制异花花粉的程度；花柱S-RNase降解自花花粉管RNA的程度也明显大于降解异花花粉管RNA的程度；温度升高到35℃时，自花和异花间花粉萌发和花粉管生长被花柱S-RNase抑制的程度不存在显著性差异；花柱S-RNase降解自花和异花花粉管RNA的程度也相似。

Effects of temperature on degradation of pollen tube RNA by the stylar S-RNase from Prunus mume were investigated, which provided an experimental basis for elucidating the mechanisms of self-incompatibility in Prunus mume.

种子1；子叶不均匀的，1个大，粉状的，保留在果里面，一个小，鳞片状从果实顶部发芽，横穿花柱道孔；无胚乳。

So far, nsLTP was proposed to promote the spreading of systemic acquired resistance signal in arabidopsis, and induce the adhesion of the pollen tube to an artificial stylar matrix in vitro, suggesting a receptor-like molecule likely exists in the cell membranes.

三级结构主要由四个α-螺旋组成，四个α-螺旋由四对二硫键相连，形成一个能结合各种脂质分子的疏水性孔穴。

Adding purified stylar S-RNase from Prunus mume cultivar 'Gessekai' to liquid medium, for cultivating self- and cross-pollen at temperatures lot, 25℃ and 35℃, respectively, then determining the rate of pollen germination and the length of pollen tube after different periods of cultivating time.

在液体培养基中添加从果梅'月世界'花柱中纯化的S-RNase，并分别于10℃、25℃和35℃条件下培养自花、异花花粉，测定不同培养时间后的花粉萌发率和花粉管生长长度；离体条件下进行果梅花柱S-RNase降解花粉管RNA反应后，用琼脂糖凝胶电泳检测不同温度条件下自花、异花花粉管RNA被降解的程度。

With increasing altitude,pollen numberdecreased and length of stylar ramification increased gradually.Increased stylarramification of plants of Saussurea with increasing altitude has importantadaptive significance of evolutionary ecology.It ensured sexsual reproductivesuccess,provided a foundation of hereditary variation and increased specificdiversity.In addition,asexsual reproduction of most species of Saussurea assuredindividual quantity.

根据我们调查，生活在青藏高原东缘的多数风毛菊属植物都具有无性繁殖方式，它保证了风毛菊属植物物种的个体数量，而花柱分枝的变长保证了风毛菊属植物的有性繁殖成功，为风毛菊属植物在该地区的进化提供了遗传变异的基础，增加了风毛菊属植物的物种多样性，使得风毛菊属植物的多数物种都成为该地区的常见种，也可能是青藏高原地区是风毛菊属植物的现代分布中心的原因之一。19。

Gynoecium 3-5(or 6)-carpelled and -loculed; ovaries axially or ± completely connate; placentation apical-axile; ovules pendulous, solitary or collateral in each locule; style terminal, stylar elements coherent or rarely distinct at base; stigma 3- or 4-branched or capitate.

雌蕊群具3-5(-6)心皮和室；子房沿轴方向合生或者几乎完全合生；顶生中轴胎座；胚珠下垂，在每室内单生或者并生；花柱顶生，花柱粘在一起或很少基部离生；柱头3-4分枝或者头状。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
