Meanwhile, the necessity and strategy of incorporation characters from Chinese native strawberry species with lower than the octoploid chromosome number into cultivated strawberry are discussed.

通过对草莓品种的系谱和遗传多样性分析，认为目前栽培品种的遗传背景狭窄圄，遗传多样性的缺乏导致对病虫害和逆境抗性的减弱，新品种培育也因此受到

The dynamic changes of physiological and biochemical indexes of healthy spikes and inoculation ones of the resistant mutants indicated that PAL activity and content and changing tendency of total phenolate and flavoniods and MDA in the healthy spikes of the mutants were similar to that of their susceptible donors, whereas, for the inoculated spikes, content and changing range of these indexes existed significant difference between two kinds of strains, changing from high-resistant variety (Sumai3 ) to their susceptible donors.

以典型抗扩展品种和突变体供体亲本为抗、感对照，对抗赤霉突变体的健康穗及接种穗的生理生化特性研究结果显示，在健康穗中，抗性突变体的PAL活性、总酚、类黄酮及MDA含量及变化趋势与其感病亲本相一致，但在病原菌侵染后，这些生理生化物质的含量与变化程度与其亲本有了明显的差异，其变化范围介于典型高抗品种和感病亲本之间，变化趋势与亲本或抗性品种一致。

White sesame E-zhi NO.2 and black sesame Zhong-zhi NO.9 were sowed at intervals as comber-sesame and autumn-sesame. The temperature and sunlight-length of different growing-stage. The result showed that seedling-stage and bud-ding-stage were temperature-sensitive and weak phototonus and temperature was the main factor in the compositive effect of temperature and light. The temperature range of 27~31℃ was optimal for sesame to produce more flowers and prolong the flowering days, but the length of flowerig-stage and practical sunlight-hour had no correlativity.

用白芝麻品种鄂芝2号和黑芝麻品种中芝9号分期进行夏播和秋播，使两个品种各生育阶段处於不同的光温条件下，用试验当年相应时段的温度和实际日照长度对芝麻各生育阶段的发育特性进行相关分析结果表明：芝麻苗期和蕾期感温性强，感光性较弱，在光温综合作用中，温度是主要因子；芝麻开花最适应的温度为27~31℃，该温度有利於多开花和延长开花期天数。

Na accumulative content of the NongDaTianYan4 and KWS0143 were higher than that of the BaoYu302 and PRESTIBEL, the accumulative content in phyllome was higher than that in tap root.

To probe into either the attractiveness to or avoidance from phylloxera of grape rootstocks and cultivars with different tolerance, as well as into the volatile components from their roots, the method of invitro root segment culture was used to investigate the selectivity of Phylloxera viticola Fitch to the roots of grape rootstocks '5BB' and '140Ru' and cultivar 'Kyoho'.

为了探讨不同抗性水平砧木及品种对根瘤蚜吸引及驱避效应以及鉴定挥发性物质组分，采用离体根段培养法测定葡萄根瘤蚜Phylloxera viticola Fitch对砧木5BB，140 Ru及栽培品种巨峰的选择性，发现根瘤蚜对栽培品种巨峰的根段具有很强的选择性，至接种后3d，67.13%的根瘤蚜优先选择巨峰；而对5BB和140 Ru的选择性却很差，分别有15.29%和17.58%的根瘤蚜选择5BB及140 Ru。

So cultivated variety of higher output and higher fastness should be chosen from the piebald leaf strain.

为此应在花叶品种中选择产量高、抗性强的品种作为栽培品种。
