查询词典 fertilization

A23187 and OA could parthenogenetically activate Urechis unicinctus oocytes and activate MAPK, indicating that the effect of fertilization on GVBD and activation of MAPK was mediated by rising in intracellular free calcium, and phosphorylation of some proteins was enough to activate the oocytes.

钙离子载体A23187和OA可以孤雌活化单环刺螠卵母细胞并激活MAPK。说明：①受精是通过钙离子的内流来激活卵母细胞并使MAPK活化的。②某些蛋白质的磷酸化状态对减数分裂是必要而且在一定程度上是充分的。

The result showed that there existed spatial variability of soil nutrients. N, P and K had medium variability, which were mainly affected by routine fertilization measures. On the contrary, Organic matter has a smaller spatial variability; Soil nutrient had semi-variance structure, and model best fit included Circular, Pentaspherical and Exponential. There existed medium spatial correlation in N, P, K and OM.

结果表明，土壤养分性质均存在着空间变异性，受常规施肥措施影响较大的碱解氮、速效磷、速效钾变异相对较大；常规施肥有机质投放较少，变异相对较小；土壤养分性质均存在半方差结构，分别拟合Circular、Pentaspherical、Exponential模型，碱解氮、速效磷、速效钾和有机质均显示中等的空间相关性。

This test mostly study the effects of black film mulching on soid most environmental factors and of black film mulching once fertilization on the growth of Platycodon grandiflorumA.

本文主要研究了黑色地膜覆盖对土壤主要环境因子的影响和黑色地膜覆盖一次性施肥对桔梗生长发育的影响。

Our results showed that fertilization tended to promote growth of Poa crymophila only in the absence of clipping.

结果表明：不刈割情况下，施肥显著促进冷地早熟禾的生长，而在刈割情况下，施肥对植物的生长没有明显的促进作用甚至有负作用。

Images showed the fusion process of male and female nuclei and polyspermous fertilization.

大量图片显示了雌雄性核融合的详细过程以及多精受精现象。

The polyspermy rate was significantly decreased when the semen samples were stored for longer (3 days). Some cleavage embryos were collected to identify their sexes in 3-4 days after in vitro fertilization. The ratio of male embryos, produced from the BTS semens stored for 1 and 3 days, were 60 % and 41 %, respectively, and 35 % and 48 % in the MIII semens.

使用不同稀释液，保存1与3日之精液进行体外受精，在培养3 - 4日后收集卵裂胚进行性别鉴定，在保存1日与3日之稀释液BTS组，雄胚性比率分别为60 %与41 %；在稀释液MIII组，保存1日与3日之雄性比率分别为35 %与48 %。

Effect of AM fungi on the growth of Populus ussuriensis under varied fertilization was studied.

在林业生产中施用化学肥料是提高作物产量的一项重要技术措施。

In order to trace the male cytoplasm transmission during double fertilization process, the mature gametophyte, zygote, proembryo and primary endosperm in Pelargonium hortorum Bailey and Rhododendron mucronulatum Turcz were investigated using transmission electron microscope and DNA staining technique.

本研究应用透射电镜及DNA荧光技术对天竺葵和杜鹃的成熟配子体以及在受精以后雄性细胞器的存在和分布进行了系统的细胞学研究，阐明了这两种植物中雌性生殖单位的超微结构特点及雄性和雌性细胞中质体和线粒体在受精作用中的传递。

Computer simulation showed that the optimum fertilization combination for L. radiata was that N, P, K fertilizer amount were 422.4-702.2 kg/hm^2, 363.6-573.4 kg/hm^2, 299.9 kg/hm^2, respectively.
