In order to establish an effective regeneration system of Lespedeza formosa, the effects of 6-BA,2,4-D,NAA and seedling age on adventitious buds regeneration,proliferation and rooting of L.formosa were studied.

以美丽胡枝子为材料，研究了6--BA、2，4--D、NAA和苗龄等因素对其子叶节再生、节段扩繁和试管苗生根的影响，目的是要建立其高效再生体系。

Seeds 1 or 2 per locule, arillate; endosperm absent; cotyledons connate.

The result shown:the growth and development of P-deficient white lupine with cotyledons were not inhibited compared with the P-sufficient white lupine.

结果表明，子叶中的磷能使白羽扇豆在完全缺磷23 d的环境中，不仅没有使干物质的积累减少，反而使干物质的积累略有增加。

On the contray,when the cotyledons were removed,the responses of P-deficient white lupine got more intensive.The accumulation of dry matter reduced and more proteoid roots were induced.The accumulation and excretion of citric acid in/from proteoid roots were enhanced,in the mean time,the root tips could accumulate and secrete malic acid.

相反，如果没有子叶磷的供给，则使白羽扇豆在缺磷环境中产生强烈的抗胁迫反应，表现在干物质的积累明显下降，根系能产生大量的排根，排根能积累和分泌大量的柠檬酸，而根尖能积累和分泌苹果酸。

Efficient usage of the main storage material in megagametophyte before it falls off from seedling is important for seed germination of Pinus edulis Engelm.. We examined and compared lipid usage in both megagametophyte and cotyledon with electromicroscopic technique, the length, dry weight, starch content and FBPase activities of each part of the seedling were measured and compared.

采用电镜技术观察了黑暗中萌发中食松子叶和提供营养的雌配子体中脂肪体和与脂肪利用有关的乙醛酸循环体的变化，测量比较了子叶、下胚轴、根的长度、干重、淀粉含量，以及果糖1，6二磷酸酶的活性变化，对贮藏物质脂类、淀粉的利用及与生长的关系进行了分析。
