    The aim of this work was to optimize the transformation system for potato（Solanum tuberosum L.）variety‘Desiree’and to obtain transgenic potato. Explants derived from potato leaves and stems were used as receptor materials to compare transformation efficiency with different time of pre-culture, Agrobacterium tumefaciens content, duration of infection and the proportion of hormones. The results showed that stem was most suitable for the induction of callus and shoots. Stem explants were pre-cultured for 2 days before infection by A. tumefaciens strain Agl-0（OD600=0.5, 10 min）and selected on MS20 containing 1.0 mg?L-1 zeatin-trans（ZT-t）, the highest transformation efficiency was obtained with 80 % of callus induction and 70 % of differentiation. R1, the gene resistant to potato late blight, was introduced into potato through above improved transformation system. PCR analysis to the kanamycin-resistant transformants revealed that R1 gene was integrated into potato genome. Transfer of R1 gene into potatoes had not any impact on agronomic traits compared to the non-transgenic line（CK）and the most transgenic lines had strong resistance to potato late blight verified by inoculation with isolate 89148-9（0）.

    Xishuangbanna cucumber（Cucumis sativus L. var. xishuangbannanesis Qi et Yuan）is one variation found only in China until now. Sowed in 8 different months in greenhouse respectively, the sex type and lateral stem of 2 germplasms were detected. The result indicated that the indexes of sex type and lateral stem development of Xishuangbanna cucumber were closely related to temperature and daylight. The development of female flowers and lateral stems of 2 germplasms expressed opposite tendency. Correlation analysis revealed a highly significant, positive association between the first pistillate flower bearing node and average temperature in greenhouse and significantly negative correlation between the percentage of nodes with female flowers to total nodes and total solar radiation. The above analysis showed that Xishuangbanna cucumbers were a kind of germplasm, which was sensible to low temperature and short daylight. The optimum sowing date in the protected field in Beijing was from the middle of August to the middle of February in the next year.

    According to GriffingⅢ, 30 crosses involving 6 inbred lines were made to analyze the combining ability and heritability of germination rate in the pod of Chinese cabbage（Brassica campestris L. ssp. pekinensis）. The results showed that the variance of specific combining ability was equal to that of the general combining ability. The germination rate in pod was affected by its parent genetic basis. It was controlled both by gene additive effect and non-additive effect and was influenced both by nuclear gene and cytoplasmic gene with less broad sense heritability and narrow sense heritability. But it was more affected by environmental conditions. We suggested that early generation selection should be done according to phenotype within expanded group of plants.

    Six generations（P1, P2, F1, BC1, BC2 and F2）derived from 2 crosses q-1×23-4G（cross 1）and q-1×A-7（cross 2）were used to investigate inheritance of the 1st node female flower and early flowering date in the summer squash（Cucurbita pepo L.）by using major gene and polygene mixed inheritance model. The results showed that the 1st node female flower was controlled by D-2 model and the early flowering date was controlled by B-1 model. Genetic effects of the 1st node female flower of 2 crosses were mainly additive effect of major gene. But additive effect and additive × dominant epitasis effect mainly played role on early flowering date of 2 crosses. Early flowering date of cross 1 was mainly controlled by additive effect of the second major gene. Heritability values of environmental effect were relatively higher on the 1st node female flower and the early flowering date. These results indicated that directional selection should be effective on the 1st node female flower, but selection for early flowering date characteristics should be carried out on high separated generations.

    This experiment chose 3 kinds of pumpkin（black seed pumpkin, brown seeds pumpkin, white seed pumpkin）as cucumber（Cucumis sativus L.）root stocks. Each 2 of them were combined as cucumber rootstocks. Cucumber plant growth, yield and wax powder characteristics were studied. The results indicated that, compared with self-rooted cucumber seedlings, the growth and yield of the cucumber grafted with double root stocks was obviously strengthened. But the yield diversity showed different compared with cucumber grafted with single root stock. The yield of the cucumber grafted with white and black seed pumpkin was much higher than the others, significantly higher than the cucumber grafted with black seed pumpkin or white seed pumpkin single root stock. The yield of cucumber grafted with black seed pumpkin and brown seeds pumpkin was significantly higher than the cucumber grafted with single brown seeds pumpkin root stock, but there was no significantly difference compared with the cucumber grafted with single black seed pumpkin root stock. There was no significantly difference between the yield of cucumber grafted with double root stocks which were brown seeds pumpkin and white seeds pumpkin and the cucumber grafted with single brown seeds pumpkin or white seeds pumpkin root stock. The influence on the cucumber surface wax powder was obvious different between the 3 kinds of pumpkin root stocks, black seed pumpkin had no de-waxing powder ability, brown seeds pumpkin had stronger de-waxing powder ability, while color of the cucumber grafted with brown seeds was bright green, without wax powder and it was a good merchandise. The wax powder influence on cucumber grafted with double rootstocks lies between the cucumbers grafted with 2 single rootstocks, and tends to the heavier wax powder root stock.

    This paper studied on the effects of different light qualities on growth and chlorophyll fluorescence parameters of garlic（Allium sativum L.）seedling. Red light, blue light, red+blue（R+B）light generated by light-emitting diode were applied, and white light generated by fluorescent lamps was used as control. Effects of different light qualities on growth and chlorophyll fluorescence parameters of garlic seedling were significantly different. The height, diameter, length of pseudo stem and value of dry weight to fresh weight were the highest under red light, whereas contents of chorophyll（a+b）and carotenoid were the highest under white light treatment. The photosynthetic rate（Pn）, transpiration rate（Tr）and stomatal conductance（Gs）were the biggest under red light, while intercellular CO2 concentration（Ci）was highest under white light. The fluorescence parameters were significantly affected by light quality. Values of the maximal photochemical efficiency of PSⅡ（Fv/Fm）and Fv/Fo were the highest under red+blue（R+B）light, quantum yield of PSⅡ（ΦPSⅡ）was the highest under white light, but there was no significant difference between white and red light. The Pn of garlic seedling were significantly increased under red light, thus the growth and dry matter were also significantly increased.

    Field experiment was conducted to study ginger（Zingiber officinale Rosc.）nutrient characteristics, yield and soil fertility by different K fertilizer levels. The results showed that ginger nutrient absorption amount was firstly for K. Ginger must absorb N 6.1 kg, P2O5 2.36 kg and K2O 9.4 kg from soil, if its root-stem yield was 1 000 kg. The yield for K3 treatment was the highest, but there was no significant difference in yields between K2 treatment and K3 treatment. We could obtain by linear equation of yield and fertilization that K fertilization for the highest yield was 900 kg?hm-2. Considering the effects of different K levels on nutrient absorption and soil fertility, the optimal fertilizer rate was K2O 750-900 kg?hm-2, the optimal N and K2O proportion was 4∶5-4∶6.

    The effects of vermicompost in different volume ratios on watermelon〔Citrullus lanatus（Thunb.）Matsum. et Nakai〕yield and quality were studied. The results showed that the additional vermicompost could significantly increase available N, available P, available K, organic matter contents in soil, and increase the contents of N, P, K in watermelon plants and fruit. The concentrations of fructose, glucose, sucrose, VC, lycopene, and soluble protein were also enhanced. The fruit quality was improved and its yield was remarkably heightened. But the effect of treatment was greatly depended on the applying ratio of vermicompos. In this experiment, treatment with 50 % vermicompost showed the best results, and the full vermicompost treatment had less effect than that of 50 % treatment. But it was still better than other treatments.
