Mixing with seeds and using water saturated as antistaling material,will increase the germination percentage of the seeds and prolonge the freshness-keeping period of cutting flower .

PGA的直接拌种试验和γ-PGA水浸液的鲜切花保鲜试验对提高植物种子发芽率和延长保鲜期都有显著效果。

The result indicates that spore germination shapes prothallium at keeping wet, cortrolling temperature and covering with 75% shading rate.

结果表明：在保湿、控制温度、覆盖遮光率为75%的遮阳网的条件下孢子发芽率高，能正常形成原叶体，继续培养均能进入有性世代形成孢子体幼苗，其中在山林腐殖土和壤土按1：1的比例混合的基质上最适于孢子萌发和幼苗生长，出苗量可达3500株/m2；在杭州采集的紫萁孢子萌发后形成的原叶体、孢子体均比在湖北民族学院采集的耐高温性好。

4 kinds of crop seeds of Shawo radish, pumpkin, maize and dry radish were treated by cadmium solution with different concentrations (10, 20, 40, 60 and 80 mg/kg) to determine their germination percentage, seedling height and length of main radicel.

方法］用不同浓度(10、20、40、60和80mg/kg)的镉溶液处理沙窝青萝卜、西葫、玉米、旱萝卜4种作物种子，测定了各自的发芽率、幼苗高度及主胚根长度。

The experimental results showed that the crude toxin of Phytophthora capsici could inhibit the germination of seeds, the growth of seedlings, and the growth of pepper radicel and the callus of pepper extremely.

结果表明，粗毒素能使辣椒叶片产生与疫病病原菌侵染类似的水渍状褐腐斑，抑制辣椒种子的发芽率，抑制辣椒幼苗和胚根的生长，抑制辣椒愈伤组织生长，并且粗毒素的这些抑制作用随着其浓度的升高而变强，不同品种所得出的实验结果一致。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.
