In this study, we developed the plant regeneration system of island cotton Gossypium barbadense L.

本研究通过诱导海岛棉下胚轴的体细胞胚胎发生建立了海岛棉的植株再生体系；并以新海16胚性愈伤组织为受体，通过农杆菌介导法进行了SATI基因的遗传转化，获得了转基因再生植株。

Gynoecium superior, of 1-5 distinct carpels with adaxial-basal style; ovary with (1 or)2(-5) ovules; ovule basal-marginal or marginal; style gynobasic; stigma clavate to capitate.

雌蕊群上位，具有1-5个离生的心皮和正面基生的花柱；子房具(1或)2(-5)胚珠；胚珠生于基部边缘或者边缘；花柱着生子房基部；柱头棍棒状或头状。

Therefore,foliar spraying ofboron was the main measure during flowering period so as to stimulate thegermination and growth of pollen tube,regulate endogenous hormone balance ofovary and promote gynospore formation and,during the phase of young embryodevelopment,spraying of relevant plant growth regulators and potassiumsupplement were essential to stimulating the increasing of endogenous GA1/3 andiPAs,raising the key nutritious substance content in ovary and promoting youngembryo development.

因而花期调节以喷B为主，以便促进花粉管萌发生长，调节子房内源激素平衡，促进大孢子形成；幼胚发育期以植物生长调节剂喷布和K素补充为主，以便启动子房内源GA1/3、iPAS等上升，增加还原糖、淀粉、蛋白质积累和K素吸收，促进幼胚发育。

Protein reserves riched in the cytoplasm of haustorial cells, especially in the site between haustorial cells and endosperm cells.

胚乳吸器的细胞质，尤其是与胚乳本体细胞交界处的细胞质富含蛋白质。

Objective To observe the development of mouse kidney in vitro at embryonic day 12、14、16 and postnatal day 1, and compare with the development of homeochronous kidney in vivo.

目的 观察胚龄12、14、16、以及生后1天的肾组织体外培养的发育情况，与同期在体发育进行比较，探讨肾组织体外培养的胚龄选择。

Objective To observe the development of mouse kidney in vitro at embryonic day 12、14、16 and postnatal day 1, and compare with the development of homeochronous kidney in vivo. And to select eligible the embryonic age for kidney culture in vitro.

目的 观察胚龄12、14、16、以及生后1天的肾组织体外培养的发育情况，与同期在体发育进行比较，探讨肾组织体外培养的胚龄选择。

Cotyledon and hypocotyl ' s rate and quamity are the most among these explams , and callus can be obtained in 10 days by cotyledon and hypocotyl . reversely it is difficult to indue callus with root , and the callus from root is lnde and easy to become browning . the calius obtained from leaf grows very slow and does not become browning uniill in 2 or 3 months

银杏的不同器官和组织都能够诱导出愈伤组织来，其中，子叶和胚轴10d左右全部愈伤化，诱导速度和诱导率均最高，根则很难诱导，愈伤组织很少，褐化很快；叶片诱导的愈伤组织，生长慢，褐化也慢，在培养基上保持两三个月而不褐化；胚乳的诱导时间也较长，需要30d左右。

The results showed that isozyme PAGE was rapid and inexpansive, but the munber of isozyme was lirnited. Endersperm of embryo protein PAGE was simple and a great deal of protein band could be found.

结果表明：同工酶电泳法速度快、成本低，而提供的多态性有限；胚乳或种胚蛋白质电泳法简单易行、在一些作物上具丰富的多态性；DNA电泳法能提供最丰富的多态性，但目前分析过程还较复杂。

The present study has built a solid foundation for identification, characterization, gene cloning and standardization of relation proteins in the embryogenic tissues of Larix leptolepis.

从本研究所获得的具高分辨率日本落叶松胚性愈伤组织蛋白质图谱，将为今后与愈伤组织的分化能力相关的蛋白质的检测、分离和基因克隆，以及胚性能力相关蛋白标准化的制定等提供参考。

By determining the extract to the chicken embryo's maximum lethal concentration and hemagglutination. By different medicine liquor concentration direct action in virus, inoculate embryo determine the change of virus titer, found that all 8 compoundings have the effect of antivirus, and Mahuang is the essential component.

测定提取液对鸡胚的最大致死浓度和对红细胞的凝集作用；以药液的不同浓度直接作用于病毒，接种鸡胚检验病毒滴度的变化，观察发现8种配方都有抑制病毒的作用，其中麻黄是发挥抗病毒作用的主要成分。
