GA3对牡丹种子发芽及幼苗生长的影响

The Effect of GA_3 on Seed Germination and Seedling Growth of Paeonia Suffruticosa

4℃低温处理已生根牡丹种子20d，发芽率可达70.0%，发芽时间缩短为70d。

The germination ratio was 70.0 % and the germination time of seeds was 70 d when peony seeds were stored in 4 ℃ for 20 d.

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；

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 .

而大田对照牡丹种子发芽率仅为52.0%，发芽时间长达190d。

But the germination ratio of seeds which growed in the field was 52.0 % and the germination time was 190 d.

多花野牡丹种子萌发和贮藏特性的研究

Treated with different materials , peony seed embryo was cultured in vitro under different light and medium conditions .

研究了光照和温度对紫毛野牡丹种子萌发的影响及种子在不同温度下贮藏后的发芽力变化。

The effects of temperature and illumination on seed germination of Melastoma penicillatum and changes of germination capacity during its storage under different temperature were studied .

不同贮藏方法及激素、稀土等对牡丹种子发芽及幼苗生长的影响

Effects of the Different Storage Methods , Phytochrome and Rare Earth Element on the Germination of Tree Peony Seeds and the Growth of Tree Peony Seedlings

采用化学和物理手段处理已生根凤丹白牡丹种子，均能打破牡丹种子的上胚轴休眠。

It was effective to hasten the breaking of the epicotyl dormancy after the peony seeds were treated with physical and chemical methods when the length of the roots of the seeds reached to 5 cm .

多花野牡丹未成熟种子的含油量为5.31%，成熟种子的含油量为4.17%。

The content of the unripe fruit seed oil is 5.31 % and that of the ripe fruit seed oil is 4.17 % .

笔者探索了牡丹容器育苗的方法和解除牡丹种子上胚轴休眠的方法。
