There were 2 peaks of starch accumulation in the process of somatic embryogenesis,the first time was at the stage of embryogenic callus,the second time was at the stage of globular embryoids;and a small raise appeared at the stage of torpedo-shaped embryoids,and the content of starch was slightly higher than those of heart-shaped embryoids and cotyledonary embryoids.With the development of embryos,the tendency of the changes of the content of DNA,RNA and the total nucleic acids was approximately similar,and the peak values were all at the stage of cotyledonary embryoids,and the change of the content of RNA was more remarkable than those of DNA and the total nucleic acids.The tendency of change of the content of proteins almost took on the S-shaped curve.

结果表明：龙眼胚性愈伤组织体胚发生过程中淀粉有2个累积峰值，第1次出现在胚性愈伤组织阶段，第2次出现在球形胚阶段，在鱼雷形胚阶段又有一个小回升，这时淀粉积累较心形胚和子叶形胚阶段高一些；随着胚胎的发育，DNA、RNA、总核酸含量的变化趋势大致相同，最高点均出现在心形胚阶段，其中RNA含量的变化较DNA、总核酸含量明显，蛋白质含量的变化曲线呈&S&形。

Result The ordinary broad sense heritability rates of various traits were at extremely significant level, specially, that of bell weight, lint percentage, top stem thickness were more than 50% and that of the ginned cotton output per plant, bells per plant, plant height, stem thickness of cotyledon node were lower. The ordinary narrow sense heritability of the ginned cotton output per plant and bells per plant were 24% and 25% resp. and that of bell weight and lint percentage etc. were lower or zero.

结果］各性状的普通广义遗传率均达极显著水平，特别是铃重、衣分、顶部茎粗的普通广义遗传率达50%以上，单株皮棉产量、单株铃数、株高、子叶节茎粗普通广义遗传率较低，单株皮棉产量和单株铃数的普通狭义遗传力分别为24%和25%，铃重、衣分等性状的普通狭义遗传力较低或为0。

The optimal condition of regeneration system in vitro culture of lettuce was Murashige and Skoog\'s medium supplemented with 0.2 mg/L 6-benzylaminopurine,0.1 mg/Lα-naphthaleneacetic acid,and using the cotyledons of seedling with 2～3 days-old as explants.The interaction of BA×NAA played an important role in the expression of regeneration responses.

生菜离体培养再生芽的最优分化条件组合为MS附加BA 0.2 mg/L，NAA 0.1 mg/L，外植体为2～3 day的子叶；其中，BA及NAA的交互作用对植株再生有重要的影响。

The main results are as follows: 1.Through the solvent contrast test and the single-factor tests ensure that the best extraction solvent and the relevant factors effect on extraction rate.Orthogonal tests are use to assure the optimal method of extracting phenol compounds from Pistacia vera L .

主要结果如下： 1、通过溶剂对比试验及单因素试验确定了从阿月浑子叶片中提取总酚的最佳提取溶剂及影响浸提率的相关因素，并通过正交实验优化了最佳提取工艺条件：利用80%的丙酮水，按1：50的料液比，在60℃下连续浸提两次，每次60min。

The experiment result showed: when the medium was MS supplemented with 2,4-D2.0mg/L, BAl.0mg/L and NAA0.5mg/L, the callus induction rate of the cotyledon was 87.9%, the callus induction rate of the plumular axis was 82.9%, and the callus induction rate of the terminal bud was 6.7%.
