Traditionally, pollination by wind has been viewed as a reproductive p rocess marked by random events in which the vagaries of the wind are compens ated for by the generation of vast quantities of pollen, so that the ultimat e production of new seeds is assured at the expense of producing much more p ollen than is actually used.
传统上,风媒传粉被看成是这样的繁殖过程:其特征就是由一些随即事件的发生,在这些随机事件里,风的反复无常被大量的产生花粉所补偿,以至于新种子的最终产生被保证了,其代价是产生远远多于实际使用量的花粉。

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。

Yunnanensis. The pollens of dehisced anthors of flowering P. polyphylla plants was slightly painted on the slide glass, the activities of P. polyphylla pollens were determined resp. by iodine-potassium iodide dyeing method (I2-KI), triphenyl tetrazolium chloride staining method, aceto carmine dyeing method and fluorescein diacetate method with a little improvement.
方法]将滇重楼开花植株裂开花药的花粉轻轻涂抹载玻片上,分别用碘-碘化钾(I2-KI)染色法、氯化三苯四氮唑染色法、醋酸洋红染色法和略有改动的荧光素二醋酸酯法对滇重楼花粉活力进行侧定。

The seeds of Adzuki bean were irradiated by 60 Co γ ray of 0~700Gy.The results showed that:(1)The sub\|lethal dose(LD 50 )was 389Gy and the early seedling leaf at M\-1 showed incised,chlorotic,yellow,mosaicand curly edge.The absorbed dose was related with the rate of misshaped leaf.Chromosomal aberration, chromosome bridge and fragment of M\-1 in the tip were observed.If the seed was irradiated with 400Gy,the rate of abnormal cell at the root was more than 10%.The relationship between pollen fertility and irradiation dose was negative correlated.
