Several types of male sterility (MS) in cabbage were investigated. The results i ndicated that using male sterility in 81132 controlled by a recessive gene only 50% male sterile plants can be achieved. Nigra cytoplasmic male sterili t y in CMSn78091 is associated with small nectar glands and un-fully opened flowe rs. Radish cytoplasmic male sterility in R1cc409 has problems of poor seed sett i ng and chlorosis at low temperature. It is difficult to apply these three mater i als in cabbage breeding. Male s...
The summer Chinese Cabbage cultivar -‘Chun Xiawang ’ was used in the experiment with orthogonal design. The characters of sensory quality，safe quality (content of NO-3-N and NO-2-N) and nutritive qu ality (content of VC，amino acid，crude fibre，soluble sugar，pH，Ca，Fe and Zn) were collected. The results were analyzed by fuzzy comprehensive evaluating me t hod. Tbe optimum fermentative condition with lactic acid bacteria for pickling C hinese Cabbage is：using 1% salt，fermenting at 30℃，inoculatin g 105 lactic...
The effect and their optimal concentration of sodium b e nzoate (A)，potassium sorbate (B)，sodium sulfite (C) on the storage of watermel on were studied by single factor experiments and cross experiments. And the cha r acteristics of antifreezing，anti-high-temperature of watermelon preservative were discussed. The results indicated that the optimal concentrations of sodium b enzoate，potassium sorbate were 1800mg·L-1 and 15 00mg·L-1 respectively，which increased the rate of non-decayed w atermelon that store...
The development of Spodoptera exigua (beta armyworm) larvae has to go through 5 instars. They keep together to damage hosts until 3rd instar，then disperse and the 4th and 5th instar larvae make the most damage. The occurring peak of S.exigua is in August and September，feeding on many kinds of plants but mainly on vegetables and bean. Spraying 32%“Decisdan” and“Cascade” can get efficient control of the pest.
Zhongjiao No.11 is a mid-early maturity F1 hybr id devel oped by crossing female parent 91-126 with male parent 92-2-3. Its yield is 45-75t·hm2. It is resistant to TMV，middle resistant to CMV， a n d tolerant to humid and heat. It is particularly suitable for cultivating in op e n field during winter in south of China，and in both protected condition and ope n field during early spring in north of China. It has been widely extended in G u angxi，Hainan，Shandong and Beijing，and has been spread for over 1500 ...
