In March and August, 1978, we achieved two self-pollinated and fruitful pure diploids by anther culture in vitro, amounting to 115 seeds. Seeds from first plant was sown in May in field for observation of progenies with their parents. In Feb-ruary and March 1979, we achieved five self-pollinated and fruitful plants five self-pollinated plants between lines, and one cross-pollinated plant.Experiment proves that the second generation (H2) of plants from anther culture in vitro are almost similar. We have received...

The brown alga Laminaria japonica is an important seaweed widely cultivated in this country. The inheritance of its frond length and width has been studied. This paper discusses only the inheritance of the frond thickness.According to our observation the development of the frond thickness was influenced by many environmental and genetic factors.Evidences collected showed that the frond thickness was a genetic character. Firstly, the frond thickness showed a positive correlation of r=0.820 between the parent and the offspring in our experiment. Secondly, the frond thickness of breed II3 was observed to be significantly greater than that of breed H4 for four successive years.The frond thickness was found to be a quantitative character, showing a continuous variation. Multi-factors were believed to control the growth of the frond thickness.The genetic factors were suspected to act on the cell-size and the number of cellular layers in the cortex of the frond. The thick-frond breed H3 possessed six cell layers more than the thin-frond breed H4. Observations on the early growth of the germlings showed that the genetic factors seemed to begin to act in the young spc-rophytes about 2-4 mm long.As the natural population of this seaweed was found to be very heterozygous in genetic content, various inbred lines or breeds with different frond thickness could be obtained by intensive inbreeding and vigorous selection.

本文报道连续四年观察几个海带自交系叶片厚度的生长情况,得到了以下结果:(1)亲本海带叶片的厚度与子代的叶片平均厚度之间有着十分显著的正相关;不同自交系海带累代保持各自叶片平均厚度的特征,即厚叶品系(H_3)的叶片总是最厚的,薄叶品系(H_4)的叶片总是最薄的。这表明海带叶片厚度是一个遗传性状。(2)海带叶片厚度是一个典型的数量性状,呈连续变异。它的遗传方式可能是属于典型的数量遗传,受微效多基因的控制。(3)海带叶片厚度的遗传因子主要是作用于叶片的皮层组织,它控制皮层组织细胞的层数和皮层细胞的大小。

The development of embryo sac in Prunus americana Marsh var. is often abnormal. The number of egg apparatus cells, polar nuclei, antipodal cells, and their situations in the embryo sac may be abnormal. The structer and behaviour of the nuclei of the egg apparatus cells, polar nuclei, antipodal cells may be abnormal. The nuclear substances may migrate out.Fertilization is often abnormal. The number, size, morphology, and structure of the spermatids entering the embryo sac may be variable. The spermatidsmay be tad-pole shaped, probably helpful for spermatid active motion. There may be polysperms entering egg apparatus, mono-fertilization or single polar nuclear fertilization. The chromatic substances of the spermrnatids may migrate out.The abnormal development of embryo sac, abnormal spermatids and abnormal fetilization induce degeneration. Thus the nuts decay and the fruits drop early. For controlling we suggest apply methods of changing genetic characters.

鸡心李(Prunus americana Marsh var.)胚囊发育多数不正常。卵器,极核,反足细胞的数目和在胚囊内的部位有不正常。卵器细胞核,极核,反足细胞核的结构动态有不正常。核物质有穿出现象。 受精作用多数不正常。进入胚囊的精子数目、大小、形态、结构有差异。精子有蝌蚪形者,可能有利于主动运动。有单精受精,多精进入卵器或单极核受精。精子染色质有穿出现象。 胚囊发育不正常,精子不正常,受精作用不正常,导致败育,果仁腐烂,果实早落。防治方法建议用人工引变,改进遗传性状。
