The results of biochemical analysis indicated that the content of GA 3 increased and the content of ABA decreased in cotyledons during the breaking of epicotyl dormancy, and the contents of endogenous growth regulators changed only slightly in the endosperm. We suggested that cotyledons be a key part controlling the epicotyl dormancy in peony seeds.
生化测定结果表明:在低温打破牡丹种子上胚轴休眠过程中,子叶中的萌发促进剂GA3 含量明显升高,抑制剂ABA 含量显著下降;而胚乳中的各种激素含量则变化不大,胚轴中的激素变化无明显规律,因此认为子叶是控制牡丹种子上胚轴休眠的关键部位。

Statistical methods designed specifically for mapping QTL controlling endosperm trait have been proposed by several researchers in recent years, but these methods all ignored the influence of the maternal genom.

DMBQ, ferulic acid and resorcin were effective chemical signal substances in the process of seed germination and haustorium formation of Cistanche deserticola. 4.The embryo is consist of 12 cells, the endosperm cell degraded so as to provide nutrition for the embryo development .As a result, germ tube differentiated from the embryo and came out through micropylar end, the small cell at the tip of the germ tube held the capacity of cleavage and the other cells grew big ,so the germ tube elongated .The anterior extremity of germ tube swelled to form haustorium under chemical substances treatment, the haustorium cell stained ,especially its portrait because of the lignification of the cells.
肉苁蓉种子的胚是由12个细胞紧密排列形成的圆球状胚,球形原胚分裂增殖的同时,胚乳细胞分解,为胚细胞的增殖提供营养,最终胚上分化出的芽管由珠孔端冒出,芽管前端细胞较小,具有旺盛的分裂能力,后部细胞体积增大,芽管逐渐伸长,在化学物质的诱导下,芽管由中部至前端细胞膨大分化出初生吸器,初生吸器呈帽子状,而这些细胞比其周围的细胞着色深,吸器纵向局部区域的番红染色加深,细胞高度木质化。

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。
