自花授粉

It is a mechanism that helps prevent self-pollination and is most common among wind-pollinated and unspecialized insect-pollinated flowers, as in figwort.

是一种避免自花授粉的机制，在风媒花和非专性虫媒花中最为普遍，比方说玄参。

Were done and no positive reaction was found.5. The DNA of the young leaves of 132 Bt transgenic plants was extracted to do PCR Five positive inversion plants were obtained and the inversion rate was 3.8%.6. The DNA of fire positive inversion plants obtained in Dl generation was extracted and tested. Two stable positive inversion plants were obtained in D2 generations.7 The way of flourescent mirror flat was used to observe the pollen tube extension circumstance in the flower post after self-pollination.

检测了132株，没有发现阳性反应。5、对转入Bt基因的132株植株的幼叶提DNA，作PCR检测。D1代获得5株阳性转化植株，分别是90035的4株，85—593的1株，转化率为3.8％。6、将D1代获得5株阳性转化植株的种子在温箱中发芽，提取DNA检测，得到D2代稳定遗传的阳性转化植株2株。7、应用荧光镜制片法观察大豆自花授粉后花粉管在花柱中延伸情况。

High outcrossing rate might lead to high gene flow frequency and the maximum frequency of gene flow was determined by outcrossing rate.

实验结果显示，强烈的自花授粉竞争可能是导致栽培稻品种间极低的异交率以及基因漂移频率的主要原因之一。

Rice is to be the root system, adventitious roots developed for conical panicle inflorescence, self-pollination.

水稻属须根系，不定根发达，穗为圆锥花序，自花授粉。

Genetic analysis of the mutants revealed that rice GA-deficient mutations are not transmitted as Mendelian traits to the next generation following self-pollination of F1 heterozygous plants, although GA-insensitive mutations are transmitted normally.

遗传分析表明该突变体，水稻遗传缺陷的突变是不转发给下一代孟德尔性状以下自花授粉的 F1的杂合的植物，虽然遗传不敏感突变是正常传送。

Some carnivorous species, such as this budding sundew, can self-pollinate if no insect emissary can be enlisted.

有些肉食类植物，就像这株发芽的毛毡苔，在没有昆虫帮助的情况下，可以自花授粉。

The selection methods applied in soybeen breeding are those used in improving autogamous plant species.

大豆育种工作中应用的选择方法即是那些用于改良自花授粉植物的方法。

The brown seeds percentage did not have significant differences in bagged and controlled. S. salsa is probably an autogamous plant.

对套袋和不套袋的盐地碱蓬比较发现，它们的结实差异不显著，所以盐地碱蓬很可能是自花授粉的植物。

Medicago truncatula has become a useful model plant for biology and genome of Legumes,since it has a small diploid genome(2×8),rapid reproductive cycle,autogamous fertilization,nitrogen-fixing,and ease of transformation.

由于蒺藜苜蓿具有高的遗传转化效率、生长期短、染色体组为2×8、基因组小、自花授粉、固氮等特点，使它成为豆科生物学和基因组学研究的模式植物。

Characters of genetic diversity are followed Three allozyme loci AAT-3, PGD-1 and PGD-2 are monomorphic. The IDH-1 was silence in S.glauca but it was active in S. itlica and S. virids. Genetic diversity of green foxtail was more than that of most of other annual primary self-pollinated plant. The yellow foxtail was complex.

我国北方青狗尾草遗传多样性特征是：AAT-3、PGD在所有供试种源中均表现单态，金狗尾草与青狗尾草和谷子相比，IDH—1表现沉默，青狗尾草同其它一年生以自花授粉为主的植物相比表现更高的遗传变异性，金狗尾草表现为倍性复合体。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
