Arabica咖啡是自受精的,因此你将不需要担心受粉。

Unicolor in autogamy shows different the seed-setting percentage in different pollinating methods, with the result as the higher rate of self-fruitfulness through xenogamy. Based on hybridization, genetransferring through pollen-tube pathway to Lilium davidii van Unicolor is researched. The master of basic technique of exogenous DNA transferring to Lilium davidii var.

Fig species are usually exclusively pollinated by a unique species of pollinating fig wasp.

榕树和榕小蜂(昆虫纲:膜翅目:榕小蜂科)是研究协同进化的经典范例之一。

The population size of the single non-pollinating fig wasp species hardly shows the negative correlations with pollinator's. The total population size of all NPFWs is positively correlated to the pollinator's. It might be the evolutionary adaptation for coexistence of the many species within a syconium.

自然种群数量分析表明,单个非传粉榕小蜂物种的种群数量几乎不与传粉榕小蜂种群数量呈负相关,而所有非传粉榕小蜂物种的种群个体总量与传粉榕小蜂的种群个体数呈正相关,这可能是多个物种共存于单个榕果内的进化适应。

The conversion boundary of self-incompatibility was researched by sowing by stage. Sunshine of day and temperature was studied critically by investigating leafage and researching traits indoors. The results showed that the daily minimum temperature was the principal factor of affinity conversion and the affinity conversion boundary was 16.5~18.1℃.HE97 was primarily regard as self-incompatible line in this research. The method was by inbreeding and sib HE97, Half the silk of HE97 and Zheng58. Inbreeding and cross have been done simultaneously. The extending condition of pollen tube was observed by dying the silk after pollinating 4 hours. The individuals with pollen tube were observed having seeds, while the individuals without pollen tube were observed having few seeds or no seeds. So this study regard HE97 as sporophytic self-incompatibility .The planting ration of female parent HE97 and male parent 87-1 was 4:1.The nature cross-pollination was studied by the theory of endosperm xenity, the study show that the setting percentage of HE97 was 625%, in which the seed in self was 70% and the seed in hybrid was 30%. This was consistent with the study of silk anatomy structure, then come to the same conclusion: compatible pollen germination and fertilization can stimulate the self-incompatible pollen germination and fertilization in the same corn cob.

通过分期播种,进行了光温敏自交不亲和材料HE97亲和性转换区间的研究,依据田间跟踪调查叶龄及室内考种研究了HE97亲和性转换区间的光温临界值,结果表明:1日最低温度是影响HE97自交不亲和性的主要原因,亲和性转换区间在16.5℃~18.1℃之间。2通过HE97自交和姊妹交以及将HE97与郑58作为双亲,各自的花丝一分为二,分别正反交,授粉后4个小时分别取其花丝进行固定、染色,观察花粉管的伸长情况,根据结实率与花粉管伸长的对应关系,结果发现观察到花粉管的对应植株收获到了种子,而没有观察到花粉管的对应植株结实率极低或没有结实,本研究把HE97初步划为孢子体自交不亲和类型。3以HE97为母本,87-1为父本,按4母:1父行比,通过花粉直感效应研究天然异交率,结果母本HE97结实良好(62%),其中自交粒占70%,异交粒占30%,结合花丝切片观察表明,亲和花粉的萌发及受精会导致落在同一果穗柱头上不亲和花粉的萌发不再受抑制。

After pollinated 50days the result indicated that fruit shape index weight of single fruit and volume of single fruit on Suli pear variety during fruit growth were significant different because of pollex xenia action of some of different varieties pollinating on Suli pear variety .

选用当前生产中推广的8个梨优良品种给酥梨授粉,授粉后50d调查分析,结果显示:由于授粉品种的花粉直感作用,使得酥梨果实的果形指数,单果重及体积发生变化,一些品种间存在着显著差异。

In this paper, we describe the characteristics of major pollinating insects and discuss the methods for studying foraging behavior of pollinating insects and factors potentially influencing pollinator behaviors.

本文介绍了主要的传粉昆虫种类及其特征,并探讨了昆虫访花行为及其影响因素的研究方法。

Our results indicate that the plant can only abscise fruits oviposited by parasitic wasps before pollinating wasps in fig-fig wasp mutualism, but do not abscise the fruits parasitized by wasps ovipositing simultaneous or later than pollinating wasps, implying that abscission can not sufficiently maintain the fig-fig wasp mutualism.

结果表明:脱落机制并不能完全阻止非传粉小蜂的寄生,榕树只能选择性地脱落掉先于传粉小蜂产卵的榕果。这也同时表明维持榕树与榕小蜂互利共存的机制不仅仅只有榕果的脱落机制,可能还存在其它未被发现的机制。

From August to November 2005, the ovipositing behaviour of two non-pollinating fig wasps of Philotrypesis in Ficus hispida figs were observed, the figs at post-flora phase were dissected to test the distribution patterns of galls used by the two non-pollinating wasps, and the quantity of wasps in figs were counted from different fig crops of three different years.
