菜苔

紫色菜苔天然色素提取工艺的研究

Study on extraction of a kind of natural Pigment from purple bolt

选择单核靠边期比率为50-70%的小孢子，将密度设为1.5-2个花蕾／ml，添加0.3mg／ml活性炭有利于大白菜和红菜苔小孢子胚胎发生。

The treatments , such as the selection of 50-70 % late uninucleate microspores , density of 1.5-2 buds / dish and addition of 0.3mg/ml activated charcoal , are helpful to microspore embryogenesis in Chinese cabbage and purple flowering stalk .

红菜苔种株采收适期的研究

A Study in The Optimum Harvest Time For Brassica campestris var. purpurea Seed Plant

红菜苔叶片叶绿素含量、叶面积指数及比叶重与群体光合速率成正相关；

B.campestris content of leaf chlorophyll , leaf area index , leaf area-weight ratio were positive significantly correlated with the PR.

红菜苔与白菜具有很多相似的生理、遗传特性，是白菜的一个变种。

Purple Flowering Stalk which is a unique variety of Chinese cabbage has similar physiology character and genetic background with Chinese cabbage .

菜心生长发育及产品器官形成的研究&菜苔生长发育的内部结构

Study on the growth , development and formation of product organ in Brassica parachinensis ── the structure in the growth and development of flowering stem

菜苔氨基酸含量高，口感好；该蛋白必需氨基酸的含量较高。

It has a strong capacity of adaptation to various ecological conditions and the content of amino acid is higher . The protein was estimated to contain high level of essence amino acids .

在主苔采收时，基部留45片叶和23个侧苔，能提高侧苔商品率、产量及菜苔总产量。

The lateral peduncle could grow faster , the commercial and total yields be increased when 4-5 leaves on the base of main stem and 2-3 lateral peduncles were kept as to pick the main peduncles .

本研究选取大白菜、红菜苔和甘蓝3种芸苔属蔬菜，研究了影响小孢子培养和植株再生过程中的诸多因素，获得了大量胚状体和再生植株。

Some factors during microspore culture and plant regeneration were explored for 3 kinds of Brassica vegetables ( Chinese cabbage , purple flowering stalk and cabbage ), a large number of embryoids and regenerated plants were obtained .
