叶用芥菜

叶用芥菜小孢子培养热激处理的适宜温度为33℃，时间为24h。

The optimum temperature of leaf mustard heat shock treatment was 33 ℃, 24h .

通过高效液相色谱分析（HPLC）发现，叶用芥菜中的类黄酮为槲皮素和山萘黄素，山萘黄素是槲皮素含量的2.46倍。

Quercetin and kaempferol were found in leaf mustard by HPLC analysis , and the kaempferol content was 2.46 times as quercetin content in leaf mustard .

品种差异及氮、硫处理对腌制叶用芥菜中营养元素（N、S、P、K、Ca、Mg、Fe）含量均有显著影响，并呈现不同的变化规律。

Cultivars , nitrogen , sulphur significantly influenced the nutritional elements ( N , S , P , K , Ca , Mg , Fe ) content in pickled leaf mustard , and different change trends were observed .

随着氮肥量增加，叶用芥菜的色素物质（叶绿素a、叶绿素b、β-胡萝卜素、叶黄素）和维生素A含量均呈显著的上升趋势，但当氮肥量超过200kg/ha时，其含量变化稳定。

The chlorophyll a , chlorophyll b , β - carotene , lutein and vitamin A content in two cultivars of leaf mustard were significantly promoted by increasing nitrogen supply , but when the dose of nitrogen was higher than 200 kg / ha , their contents were stable .

菠菜NO3－含量，以叶肉部分最低，根部次之，叶柄部分最高，叶用芥菜因类型不同而有变化。

There was significant difference among different orgen tissues in spinach : AS the nitrate content , the leaf pulp section was the lowest that of root section ws and that of leaf stalk was highest .

叶用芥菜（BrassicajunceaCoss.）是加工腌制蔬菜的重要原料，随着腌制蔬菜加工产业的迅速发展，市场对叶用芥菜的需求量逐渐增大。

Leaf mustard ( Brassica juncea Coss . ) is an important raw materials for processing of pickled vegetables . The market demand of leaf mustard is gradually increasing with the rapid development of the pickled vegetable processing industry .

增加硫肥量，叶用芥菜的抗坏血酸和谷胱甘肽含量得到了显著提高。

The AsA and GSH content in leaf mustard were significantly increased by sulphur application .

但由于缺乏优良的叶用芥菜雄性不育系，目前生产上栽培种植的叶用芥菜都是常规品种。

However , the cultivars of leaf mustard in production are all conventional because of lacking perfect male sterile line of leaf mustard .

采用榨菜细胞质雄性系为不育源，通过变种间杂交和回交的方法，转育叶用芥菜细胞质雄性不育种质。

The cytoplasmic male sterility ( CMS ) was transferred into leaf mustard by inter varietal hybridization and subsequent backcrosses cms donor as using tuber mustard .

然而，在山区进行蔬菜种子生产，从经济上考虑，只有萝卜和叶用芥菜种子生产有效益，而大白菜种子生产没效益。

However , when seed production was considered economically on the highland , only Chinese radish and leaf mustard seed production was profitable , but not for Chinese cabbage .

增加硫肥量，腌制叶用芥菜的蔗糖含量、可溶性蛋白质和腌制包包青菜硝酸盐含量显著增加，而叶用芥菜的亚硝酸盐含量则显著降低。

Sulphur application significantly increased sucrose and the soluble protein content in pickled leaf mustard and the nitrate content in pickled leaf mustard ( cv . Baobaoqingcai ), but significantly decreased the nitrite content in pickled leaf mustard .

结果表明，增加氮肥量，腌制叶用芥菜的可溶性总糖、还原糖和蔗糖含量显著降低，而其可溶性蛋白质、硝酸盐和亚硝酸盐含量则显著增加；

The results showed that total soluble sugar , reducing sugar and sucrose content in pickled leaf mustard were significantly decreased by increasing applied nitrogen , however the soluble protein , nitrate and nitrite content in pickled leaf mustard were increased .

以叶用芥菜4个基因型为对象，观察小孢子单核靠边期与花蕾大小及瓣药比（花瓣长与花药长度比）的关系，确定适合于小孢子培养的花蕾长度。

The relation of mononuclear microspores step aside , bud size and the length ratio of the petal and the anther was investigated in four genotypes of leaf mustard , in order to determine the appropriate microspore culture of bud length .

用大白菜细胞质雄性不育系CMS22与叶用芥菜可育品系X09-1和X12-1杂交，并以叶用芥菜为轮回亲本连续7代回交，获得了2份不育性稳定的叶用芥菜细胞质雄性不育系。

A cytoplasmic male sterile line of Chinese cabbage and two male fertile lines of Leaf Mustard were applied to transfer the male sterility . Interspecific crosses followed by 7 generations ' backcrosses with Leaf Mustards as recurrent parents were carried out .

其结果如下：1.叶用芥菜花蕾长度及瓣药比与小孢子发育阶段密切相关，可据此作为小孢子群体是否适于诱导培养的指标。

Bud , petal and anther length ratio of leaf mustard were closely related to the developmental stages of microspore . We can use what I mentioned above to be a indicators , judging the Microspore population suitable for inducted cultivation or not .
