Botany development of an embryo without fertilization; development of a sporophyte from the gametophyte without fertilization.

没有受精过程的胚胎形成过程；不经过受精而由配偶体形成孢子体的过程。

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。

Seta The part of the SPOROGONIUM that forms the stalk between the foot and the capsule in bryophytes, e.g.

蒴柄：在苔藓类植物的孢子体上连接基足与孢蒴的茎状结构。

Taking self-fruitful rate as the criterion and segregating population of field survey as method, we got the result that the ratio of fertile plants and sterile plants in the three F2 population of K-cytoplasmic male sterile hybrid accords with 63:1 tested by Chi-square, therefore we can infer that the restorative mechanism of K-cytoplasmic male sterile line was controlled by three different major genes, which manifested as sporophore sterility.

结果表明：在三个K型胞质雄性不育的F2群体中，可育单株与不育单株的比例经卡方检验符合63：1的理论比例，因此可以推断小麦K型胞质雄性不育的恢复由3对主效恢复基因控制，并表现为孢子体不育类型。

This study showed that the foreign gene has integrated into maize genome and the shoot apical point of maize as receipt sporophyte in transformation was feasible and high efficient.

初步证明外源基因已经整合到玉米基因组中，以玉米茎尖作为受体孢子体的转化系统用于基因转化是可行、高效的。

In lower plants such as mosses and liverworts the persistent vegetative plant is haploid, the sporophyte being a relatively short-lived phase.

在苔藓，地钱这样的低级植物中，习见的植物体是单倍体，孢子体存在时间较短。

Hubei Shengfeng Medical Company has spent a lot of time and energy on the study of the Cordyceps sinensis and has produced a kind of similar herb. At first researchers collect funguses separated from Cordyceps sinensis that have the similar effective elements as Cordyceps sinensis. Then the funguses are inoculated on the larvae in the base. Much to the researchers' surprise, this kind of planted herb has even more nutrition and drug properties than the natural Cordyceps sinensis.

湖北圣峰药业有限公司从虫草菌天然型培养着手进行研究，从自然界采集冬虫夏草分离出来的真菌，药理功效与冬虫夏草的有效成份基本相似，接种在替代幼虫的富硒培养基上，进行固体静置培养菌丝体和分生孢子体作为有型冬虫夏草，经检测人工虫草的药性及营养成份不仅含量高於野生虫草，而且含有机硒。
