Good callus with high regeneration frequency can be obtained when scutellum of embryo at 25 days after pollination were used as expla...

最佳取材时间在开花后 15d左右，而对于在开花后 2 5d取的大龄胚，若仅挑取盾片组织进行接种，也可以获得质量较高和再生能力较强的愈伤组织

The seeds of rice mutants with Ac/Ds elements inserted from rice variety Dongjin were selected and the callus were induced from scutellum of mature embryo. Ca(superscript 2+) with different concn. was added into the selected optimum enrichment, differentiation and rooting medium to study the effect of Ca(superscript 2+) on proliferation, differentiation and rooting of rice callus.

方法］选用水稻品种Dongjin的Ac/Ds插入突变株系的种子，从成熟胚盾片诱导出愈伤组织，在筛选出的最适增殖、分化及生根培养基中添加不同浓度的Ca(上标 2+)，研究Ca(上标 2+)对水稻愈伤组织增殖、分化及生根的影响。

With high oil corn 115 as CK, the embryo, endosperm, seed capsule and the accumulation law of their corresponsive oil in grains of 2 varieties of micro-endosperm super-high oil corn were studied.

方法以高油玉米115为对照，研究2种微胚乳超高油玉米籽粒的胚、胚乳、种皮及相应油分的积累规律。

In 52 crosses, the ratio of distinct ovary enlargement to seed capsule development was 86.5%, but only 32.7% of crosses, whose seed capsules developed after 4 months. Hybrid plants of 19.2% crosses were obtained by embryo culture.

在52个杂交组合中， 86.5%的杂交组合具明显的子房膨大和果荚发育，但授粉4个月后未变黄落果的杂交果仅占组合数32.7%，经胚胎培养获得植株的杂交组合只占组合数的19.2%。

Recall that, in the Kolmogorov axiomatization, measurable sets are the sets which have a probability or, in other words, the sets corresponding to yes/no questions that have a probabilistic answer.
