It shows that BTH and its metabolites have no immediate activity against pathogens and are in accordance with criterion of chemical elicitor.

组织病理学研究表明，BTH处理小麦后接种，并不抑制分生孢子的萌发和附着胞的形成，只是菌落的发展在很大程度上受到了抑制，表现为畸形附着胞数目增加、侵入率降低、侵入速率减小、菌落扩展速率减小、产孢率降低。

This study clearly showed that mosaic variation was caused by chlorophyll deficiency mutation of shoot tip histogen layer-Ⅱ;tissue and organs originated from the layer-Ⅱ couldn't synthetize chlorophyll,thus induced albino; the albino variation appeared yellow green mosaic because layer-Ⅱ was displaced by layer-Ⅲ partly.

研究表明，其变异原因是由于茎尖分生组织的L -Ⅱ组织原层发生失绿突变，致使其衍生的组织和器官不能合成叶绿素，从而形成白化现象；又由于L -Ⅱ与L -Ⅲ组织原层层间发生部分代换，致使白化突变呈黄绿镶嵌的花斑。

Furthermore, each developmental phase showed several different phases, these included inflorescence 0 phase, inflorescence Ⅰ phase, inflorescence Ⅱ phase; spikelet Ⅰ phase, spikelet Ⅱ phase, spikelet Ⅲ phase; palea primordium phase, lodicule primordium phase, stamen primordium phase and carpel primordium phase.

在这3个大的发育时期，又根据每一发育时期中的原基分生组织生长发育的程度及先后顺序分别又可分为：花序0期、花序1期、花序Ⅱ期；小穗期Ⅰ期、小穗Ⅱ期、小穗Ⅲ期；内稃原基分化期、浆片原基分化期、雄蕊原基分化期、心皮原基分化期。

These genes exact expression is activated by flower meristem identity genes and controlled by various positive and negative regulators.

这些基因的精确表达需要花分生组织特异性基因的激活和多个正负调节因子的调控。

The breed of gilt-edged wind pear basically is to use cuttage method; It has stronger cent to give birth to ability, after be being spent every year, chairman of phyllome radical department gives new shoot, in those days autumn can cut next enter growing in pearlite and vermiculite compound matrix, wait for rooted hind go up again basin conserve.

金边风梨的繁殖主要是采用扦插法；它有较强的分生能力，每年花后，叶丛基部会长出新芽，当年秋季就可切下栽入珍珠岩和蛭石混合的基质中，待生根后再上盆养护。

Herbs, perennial, 5-35 cm tall, suberect to ascending from creeping branching rooting base; stems solitary or ± cespitose, unbranched or ± branched above.

多年生草本，5-35厘米高，来自匍匐的枝根基部的直立到上升；上面的茎单生或多少丛生，不分枝的或多少枝。

During vascular development, the meristematic cambial cells divide down their long axis in a highly orientated manner to generate clear files of cells.

在维管束的发育中，形成层细胞高度方向性地以分割长轴的方式分生产生明显的细胞队列。

The biological polymorphism of Cercospora zeae-maydis was studied systematically in the levels of histology, protein and DNA. The major characters in polymorphism of pathogen were listed as follows:(1) The great differences were seen in shapes and sizes of conidiophores, the growth velocity of mycelium and pigment-productivity of colony among pathogen strains. In addition, an albino strain, a kind of mutant, was casually discovered during isolation of pathogen from diseased plants, which supported strongly our previous prediction that there should be some potential genetic variation in Cercospora zeae-maydis.

本研究在组织学、蛋白质和DNA水平上，系统研究了玉米灰斑病菌的生物学多态性，这种多态性主要表现在以下几个方面：①病菌形态学和培养性状多态性：菌株间存在分生孢子形态、菌丝生长速度、菌落产色素能力等方面的差异，该病菌在自然界存在另一种变异类型——白化菌株，说明灰斑病菌的确存在遗传变异的潜能。

Cinerea need low pH at low temperature.

灰霉菌分生孢子在低温下萌发需要较低的pH条件，在pH4的葡萄果汁中，4℃培养72h后萌发率可达90％以上，高于pH5～7的果汁。

The feasibility of the protoplast mutagenesis for increasing productivity was studied on a Claviceps paspali strain, which was not easy to produce conidia under laboratory conditions.

为了提高在一般条件下不易产生分生孢子的雀稗麦角菌的产碱率，对原生质体诱变育种的条件和方法进行了探讨。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
