The results showed that, all the treatments can shorten the time of epicotyl germination of 'Fengdan', the 28 days chilling treatment was the shortest, and the next was 21 days chilling treatment and 300 mg/L GA3 treatment; in a certain range of GA3 concentrations, higher concentrations, higher seed germination index and germination rate in 'Fengdan'; the seed germination index and germination rate of 'Fengdan' after different time chilling treatments were higher than the control, in which, the treatment of 21 days chilling had the highest germination index and germination rate.

研究了不同时间的低温(4℃)处理及不同浓度的GA3处理对凤丹种子上胚轴萌发及幼苗生长的影响，结果表明：所有处理均能缩短凤丹种子上胚轴萌发时间，以低温28天处理初萌期最短，其次是低温21天和300mg/L GA3处理；在一定的GA3浓度范围内，浓度越高，凤丹种子发芽指数与发芽率越高；不同时间低温处理后凤丹种子发芽指数与发芽率均高于时照，其中低温21天处理是所有处理中发芽指数与发芽率最高的。

In this study, the aged watermelon seeds were selected as material, soaked by different concentrations of salicylic acid, calcium nitrate and gibberellic acid (GA3), to study the effects on germination rate, related physiological and biochemical indexes of aged watermelon seeds. The results show that the activity of aged watermelon seeds was obviously increased after soaking, and the best treatment to promote germination was Ca(NO3)210mmol/L. Besides, conductivity and soluble sugar content of seeds lixivium, and MDA content of seeds were decreased obviously after treated by SA, Ca(NO3)2 and GA3, and SA treatment had the best obvious effects.

本试验以自然老化的西瓜种为试材，采用不同浓度的水杨酸、硝酸钙、赤霉素预浸种处理，研究其对老化西瓜种子萌发及相关生理生化指标的影响，结果表明：不同处理均可显著提高老化西瓜种子活力，以10mmol/L的Ca(NO3)2处理促进萌发的效果最为明显；不同处理均能明显降低种子浸出液电导率、可溶性糖含量及种子中丙二醛含量，以水杨酸的各处理效果最好。

The results showed that the total dissoluble proteins hands of 8% and 10% gel were 91 and 97, respectively, and the seed salt soluble proteins bands of 10% gel were 69; All of the five alfalfa species have their own characteristic bands, which are different in number, distribution, width, and concentration; Among three methods, the five species' seed dissoluble protein fingerprints of 10% gel' bands is relatively more, which genetic diversity scattered in A, B and C regions, and can be repeated in different experiments. So it's the best fingerprint. The fingerprints of the seed dissoluble proteins and seed salt soluble proteins of five species are unanimous, which showed that: the hybrid has the nearest genetic distance with Medico go sativa cv.

结果显示：5/个种10%和8%凝胶电泳的种子可溶性蛋白总带数分别为97和91， 10%凝胶电泳的种子盐溶蛋白共有69条谱带；5种苜蓿在种子可溶性蛋白和盐溶蛋白电泳图上都具有各自的特征谱带，谱带数目、位置、宽窄和颜色深浅都存在明显的差异；10%凝胶的可溶性蛋白指纹图谱谱带数目相对较多，种间遗传差异在A、B、C区均有分布，谱带的重复性好，是鉴别种的最好图谱。5种苜蓿种子可溶性蛋白和盐溶蛋白指纹图谱一致，表明杂交种和敖汉苜蓿的谱带相似性最大。
