与hand-pollination相关的网络例句 [注：此内容来源于网络，仅供参考]

With 3~4-year-old Annona ateznoya Hort. as experimental materials, effects of different pollination ways, degree of petal dehiscence and anther dehiscent time on hand-pollination were studied.

以3~4年生阿蒂莫耶番荔枝为试材，研究了授粉方法、花瓣开张程度和花药裂开时间对坐果的影响。

Seven parents and twelve hybrids produced by hand-pollination in accordance with incomplete diallel cross model were included.

材料包括7个小麦亲本和由此按不完全双列杂交模式组配、人工去雄授粉产生的12个杂种组合。

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 highest fruit set percentage was obtained when hand-pollination was done in one day (at the stage of half opened petals) before the anthers naturally dehisced. Hand-pollination could increase fruit set from 2 days to 4 hours (at the stage of tiny dehiscent petals to over half-opened petals) before the anthers naturally dehisced. The pistil compatibility was strong and fruit set percentage with hand-pollination was the highest one day before the anthers naturally dehisced (at the stage of half-opened petals).

从花药自然裂开前2 d到自然裂开前4 h（相当于花瓣呈微张开到超过半张开状态），雌蕊都具有容受性，这期间进行人工授粉能提高坐果率，但以花药自然裂开前l d（相当于花瓣呈半张开状态时），雌蕊容受性最强，人工授粉坐果率最高。

When the perfect flowers were isolated and with no hand-pollination the fruit-setting rate of them was 67%,in which 60% had well-developed seeds. The purity of seed could reach 86.4% by spontaneous pollination on the perfect flowers whose stamens wrapped up stigmas.

两性花隔离后不进行人工辅助授粉的座果率为67％，其中有60％的果实有发育正常的种子；选择雄蕊将柱头基本包裹的两性花自由授粉，种子的纯度可达86.4％。
