药隔

但在大多数情况下，愈伤组织易从花丝及药隔组织形成。

In most conditions , the callus happened to develop readily from the anther filaments and connective tissues .

2绒毡层细胞部分来源于初生壁细胞，部分来源于药隔的基本组织。

对于比较重要的单棱期和药隔形成期，RMSE分别为1.8和3.2d，均没有超过4d。模型表现出较强的机理性和实用性。

And the RMSE for single ridge stage and anther separation stage , which were important to apical development for barley , were 1.8 d and 3.2 d.

ABA和ZT处理在药隔分化期及四分体时期均使小麦穗内源IAA、GA3、ZR含量降低，内源ABA含量升高。

The contents of endogenous IAA , GA3 and ZR were much lower by treated with ABA and ZT than those of the control plant at the stage of differentiation of anther chamber and formating stage of tetrad , but those of endogenous ABA were higher .

但在四分体分化期，药隔期之前ZT处理有增加幼穗可溶蛋白含量的趋势，雌雄蕊分化期处理则显著降低了幼穗可溶性糖的含量。

Furthermore , the former treatment of ZT increased the content of soluble protein and decreased the content of the soluble sugar of young spike . The contents of endogenous plant hormones varied with the stages of the young spike differentiation and development .

研究表明，不育系的温度敏感期和光周期敏感期是一致的，即在小麦穗分化的药隔至花粉粒单核期。

The results showed that the stage of photo-sensitivity and thermo-sensitivity was coincident from anther chamber formation to mononucleate .

随着四分体发展为单细胞花粉，花药壁各层以及药隔部位细胞中的淀粉粒逐渐减少，而在花粉粒中开始出现淀粉粒，到成熟花粉阶段，花粉粒中积累较多的淀粉颗粒。

With the forming of single cell pollen , starch grains gradually reduced in the anther walls but began to appear in pollen .

护颖分化期和小花原基分化期比对照品种增长5.5d和5.7d，雌雄蕊原基分化期和药隔分化期差异不大。其中，幼穗分化速度快是决定大穗小麦具有较多小穗数的主要原因。

Among them , higher differentiation rate was the major reason why there was more spikelets in big spike wheat varieties ( lines ) .

药隔和药壁组织通过质外体或共质体途径运输Ca2+供给花粉的发育；

Calcium was transported in anther wall and intervening connective tissue via symplast and apoplast system , meeting the need of microspore and pollen development .

（例如指水果和花粉囊）在成熟时自然的打开释放种子。左右两侧花粉囊之间是薄壁细胞构成的药隔，药隔中的维管束与花丝维管束相连。

( of e.g. fruits and anthers ) opening spontaneously at maturity to release seeds . Each lobe contains two pollen sacs that produce very large quantities of small pollen grains .

采用焦锑酸钾沉淀法研究了不同类型水稻不育系与其相应保持系及其可育花药药隔发育过程中Ca2+的分布变化。

Potassium pyroantimonate precipitation method was adopted to the Ca ~ ( 2 + ) distributions in the developing connectives of different sterile lines and the corresponding maintainer lines as well as their fertile anthers of rice .

其中2001~2002年采用水旱对照处理，水地分别于越冬期、拔节期、药隔期各灌水一次，旱地全生育期均不浇水；

Two levels of irrigation ( water and drought ) was treated in 2001 ~ 2002 , watered treatment was irrigated one time at winter-growing , jointing stage and anther connective stage , droughted treatment was not irrigated during the period of life .

在减数分裂过程中，绒毡层细胞中没有颗粒状的淀粉粒出现，但药室内壁和药隔薄壁组织细胞中的淀粉粒积累达到高峰，在表皮细胞中也可见少量淀粉粒积累。

In meiosis stage of the microspore mother cell , starch granules do not appear in tapetum cells but reached a peak accumulation in the connective tissue and endothecium cells . In epidermal cells can be found in a small amount of starch grain .

实验结果表明：Ca2+在不同类型的不育水稻中呈现出一定的规律性变化，药隔中Ca2+的异常分布可能与水稻花粉的败育有关。

These indicated that Ca ~ ( 2 + ) appeared to regularly vary in different sterile lines of rice to some extent and the irregular Ca ~ ( 2 + ) distribution in the connectives was probably connected with the abortion of rice pollens .

结果显示在正常花药的发育过程中，药隔中的Ca2+呈以下变化规律：（1）花药发育早期药隔中的Ca2+沉淀很少；

The results showed that the Ca ~ ( 2 + ) distribution in the connectives of the regularly-developing anthers followed the pattern that : ( 1 ) Very little amount of Ca ~ ( 2 + ) deposited at the early stage of anther growth ;
