查询词典 anther

所以本文从以上几个问题出发，以大田生长的植株作为供试材料，首次系统地研究了甘露醇预处理过程中大麦花药花粉在生理生化方面所发生的变化；以及甘露醇预处理后对大麦雄核发育和培养效果的影响。

It is concluded that there are three reasons resulted in male-sterility by floral organs abormality as follows :(1) The stomium enlongates faster;(2) Anther filaments do not elongate sufficiently to position the locules above the stigma at anthesis;(3) The anther locules do not dehisce at the time of flower opening (although limited dehiscence occurs later).

用石蜡切片技术，在光学显微镜下观察拟南芥部分雄性不育材料小孢子发育过程和各时期的花形态特征，分析雄性不育的原因。从花表型上分析导致雄性不育的原因有三个方面：（1）柱头伸长过快；（2）花药生长过慢；（3）花药开裂晚。

By using a DH population derived from a rice indica/japonica cross, genetic analyses of floral characters, such as percentage of exserted stigmas, stigma length, stigma width, style length, anther length, anther width, spikelet length, spikelet width, length-width ratio of spikelet, and panicle exsertion degree, were conducted in the present study.

In anther culturesucrose is betterbut more attention should be paid to maltose which has a positive effect in anther culture.

在植物花药培养中，蔗糖较好，但应注意麦芽糖对花药培养的促进作用。

In anther culture, sucrose is better, but more attention should be paid to maltose which has a positive effect in anther culture.

在植物花药培养中，蔗糖较好，但应注意麦芽糖对花药培养的促进作用。

Pollen plants from octoploid triticale anther culture were propagated as clone linesand had been used as anther donors for further culture in two successive years....

由八倍体小黑麦花培所得的花粉植株再进行一次花培，在所获得的 C 类植株中就能选出花培效率达到八倍体小黑麦水平的个体。

The capacity of dehiscent anther was determined to the size and the morpha of anther stomium cell, epidermal cell and fibrous stratum's plastic property of the pollen sac wall.

成熟花药开裂的能力与花药裂口细胞的大小、形态有关，同时又与成熟花粉囊壁的表皮细胞和纤维层细胞的可塑性结构功能有关。

The DGCMS plants were complete sterile at the both temperature situations, and there was no pollen sac differentiation and had smaller petals and stamens at the higher temperature situation, but there were 1～4 pollen sacs in each anther and had bigger petals and stamens at the lower temperature situation. The cytological characteristics of the anther development were the same as that of GMS plants in Yi-3AB.

表现质核不育的植株，在高温条件下，花瓣小，表现彻底的pol CMS不育，无花粉囊的分化，在低温条件下，花瓣变大，也表现彻底雄性不育，具有核、质不育的共同特点，每个花药可分化出1～4个花粉囊，但无可育花粉，其雄性败育时期和特点与宜3A相同。

The results show that: Each anther has four pollen sac, anthers from the epidermis, medicine room wall, the middle, composed of the tapetum, Mature middle and all the disintegration of tapetum; is symmetrical tetrad type, pollen is a 2 - cell-type pollen; in anther culture lei check standards should be time for about 3-4mm.

研究结果表明：每个花药具备4个花粉囊，花药由表皮、药室内壁、中层、绒毡层组成，成熟后中层和绒毡层都解体；四分体属左右对称型，花粉属2-细胞型花粉粒；在进行花药培养时取蕾标准应为3-4mm左右。关键词：铃兰；花药；解剖
