查询词典 pollination

Rhodiola sachalinensis is cross-pollinated by the 11 insect species of Lepidoptera, Coleoptera. Hymenoptera and Diptera. Ten species carry pollination on their bodies.

高山红景天异花传粉，传粉媒介是鳞翅目、鞘翅目、膜翅目和双翅目的十一种昆虫，其中十种昆虫身体上携带高山红景天花粉。

The main results were as follows. Although the anthers dehisced totally at night, their pollens had already been matured when the petals were over half-opened at 8:00 am. Therefore, hand-pollination either in the morning or afternoon with this kind of pollens could increase fruit set.

结果表明，花药在傍晚自然裂开的花，其花粉在当天上午8时，花瓣呈超过半张开状态时，就已发育成熟，上午或下午人工提取这些花粉来进行授粉能提高坐果率。

The apple trees were coming into bloom but no bees droned among the blossoms, so there was no pollination and there would be no fruit.

苹果树要开花了，但没有听到蜜蜂嗡嗡地在花丛中飞，因此苹果花没有被授粉，也自然无法结果实。

The apple trees were coming into bloom but no bees droned among the blossoms, so there was no pollination and there would be no fruit.

苹果树开花了，可是没有蜜蜂在花丛中嗡嗡地采蜜，没有蜜蜂的授粉，也就没有任何果子。

Because of their small amount, simple structure or late maturing, other types of varied flowers had no significant effect on fig-wasp pollination, oviposition or development, or maturation of syconia.

除A型外的其它类型的变异花，由于数量少且结构简单，或发育后熟，对传粉小蜂的传粉、产卵以及花序的发育、成熟没有显著影响。

The A type varied flowers with umbrella-inflorescence shape in female syconia affected pollination by fig wasps in normal female flowers, required more nutrients and growth space, and affected growth and development of normal female flowers. With a large number of type A flowers, unpollinated female syconia show delayed litter fall or hanging on the trees and loss of nutrients.

雌花序中伞形花序状的A型变异花影响传粉小蜂对正常雌花的授粉，与正常雌花争夺养分和生长空间从而影响正常雌花的生长发育，大量A型变异花的存在使未授粉的雌花序延迟凋落或挂树不落，造成养分流失。

Therefore, we suggest that pollination wasps could be introduced artificially to male syconia of phase B so as to prolong the phase D of male strains; and the match between female and male strains should be 1:2-4, namely, one female strain is cultivated with 2-4 male strains with successive D phases.

因此建议对雄株的B期花序进行人工引蜂的方法修复小蜂种群，从而延长雄性品系D期时长；而雌、雄品系配植模式应为1：2~4，即1个雌株品系与2~4个D期依次衔接的雄株品系配植。

The change of syconia number and the duration of phase B and phase D of different Ficus awkeotsang strains were compared. Results showed that the length of phase D of male syconia was about one month, while the length of phase B of female and male syconia was 2-3 months. This means that phase B and phase D could not overlap completely, resulting in the falling of syconia in phase B due to lack of wasps for pollination.

比较爱玉子不同品系雌、雄花序的B期与雄花序的D期花序数量变化及持续时间，结果表明：栽培爱玉子雄花序D期时长约1个月，而雌、雄花序的B期时长却是2~3个月，B、D期不能完全重叠，导致B期花序因没有小蜂传粉而脱落。

The results showed that although 2n pollens had a certain germinatingability,the germinating process of natural and artificia 2n pollens was tardier than that of1n pollens,and 2n pollens had weaker competition in mixed pollination than 1nbreeding practice.

应用这种方法对2n花粉生命力和发育情况进行测定观察发现，尽管2n花粉保持有一定的萌发力，但与1n花粉相比，天然和人工2n花粉的发育进程均较迟缓，在参与授精的竞争中处于劣势，这也正是育种中三倍体得率低的根本原因。

The tomato adult plant has the vigor, the growth good pollen, can promote the pollen through the vibration or the undulation inflorescence to disperse from the anther sac, and falls to the column head on, thus achieves the manual supplementary pollination the goal.

番茄植株具有活力、发育良好的花粉，通过振动或摇动花序能促进花粉从花粉囊里散出，并落到柱头上，从而达到人工辅助授粉的目的。

Aquatic or marsh-growing fern allies; known to have existed since the Cenozoic; sometimes included in Lycopodiales.

生活于水中或湿地的蕨类；从新生代生存至今；有时归于石松目之中。

The engine was uprated from a 90hp Franklin to a 125hp Lycoming.

改良过的引擎是从90hp到125hp莱康明富兰克林。
