The result showed that the scion with different bud age, grafting seedlings with different growing condition, lignification degree in grafting part of rootstock, and the scion in different seasons were substantially influent to the grafting survival rate.

结果表明，不同芽龄的接穗、嫁接苗不同的生长条件、砧木嫁接部位木质化程度以及不同季节的接穗对嫁接成活率都有较大的影响。

Method］Taking the Capsicum frutescens L.as materials, changes of POD isoenzymes zymograms induced by cion, cion wound, rootstock, rootstock wound and graft union were studied.

方法］以辣椒为试材，研究接穗、接穗切伤、砧木、砧木切伤、嫁接5个处理切伤愈合过程中POD同工酶谱的变化。

Rootstock ± vertical, 5-12 mm in diam., not tuberculate, with thickened roots along rootstock. Stem 16-50 cm tall, erect, not rooting at nodes, with 0.2-1.3 mm retrorse to patent nonglandular trichomes and rarely 0.7-0.8 mm patent glandular trichomes.

根茎多少垂直，直径5-12毫米，不具瘤，根沿着根茎加粗。16-50厘米高的茎，直立，并非根在节上，具0.2-1.3毫米对开展非腺状毛状体和很少开展腺毛0.7-0.8毫米。

Gene sequence was highly homologic with a gene encoding aβ- subunit of ATP synthetase and an EST originating from a cDNA in relation to water deficit stress, which both were closely associated with the protein functioning in stress resistance and ion transportation. The results suggested that No. 1 gene sequence was involved in stress resistance of apple rootstock. No. 2 gene sequence had high homology with a gene encoding a serine/ threonine kinase protein, indicating perhaps it was a new gene encoding the serine/ threonine kinase protein in apple rootstock. The gene sequences of A1 and A2 were highly homologic with a gene encoding aβsubunit of ATP synthetase.

对得到的差异片断进行回收、测序，通过BLAST和其它植物比对，发现Ⅰ号序列与一条编码ATP合酶β亚基基因和一条水分亏缺胁迫cDNA克隆基因EST的同源性非常高，该序列编码涉及到了抗性表达、离子转运基因，可能参与了植物抗性表达，说明获得的基因序列应是与苹果砧木抗性相关的基因；Ⅱ序列与一条serine/threonine kinase蛋白激酶的蛋白序列同源性比较高，核酸比对较低，可能是具有丝氨酸/苏氨酸蛋白激酶功能的新基因。A1、A2序列与一条编码ATP合酶β亚基基因的同源性较高。

The effects of bur cucumber as rootstock on the mass of the first fruit, the number of female flowers on the main stem in 20 nodes, plant height, area of the biggest leaf, number of leaves, stem diameter, number of nodes were in the middle of the effects of black seed pumpkin as rootstock and self-rooted cucumber.

结果表明，棘瓜嫁接可使'中农21号'黄瓜的第1雌花开放期和始收期提前，对根瓜质量、20节内的雌花数、株高、最大叶面积、叶片数、茎粗和节数的影响小于'黑籽南瓜'嫁接处理；前者的抗寒能力、净光合速率强于后者和自根苗；棘瓜嫁接对黄瓜具有增产、抗枯萎病、抗根结线虫的作用，并且果实品质显著优于以黑籽南瓜嫁接的。

The results showed that the florescence date of the first female flower and first harvest date of the cucumber plants grafted on bur cucumber rootstock were ahead of the p lants grafted on black seed pumpkin rootstock and self-rooted cucumber.

以瓜类野生种和黑籽南瓜为砧木、'中农21号'黄瓜为接穗，研究了棘瓜嫁接对黄瓜植株生长发育、耐寒性、光合速率、产量、抗病性以及果实品质的影响。

Result The results showed that tissue culture seedlings cultured with disinfection seeds and fresh fruit seeds had higher survival rates, which could reached above 75.0%. Taken Pingguoli and Xiangshuili for cions, Shanli without root for rootstock, the survival rate of graft seedlings had obvious difference. And Xiangshuili for cions had higher survival rates. Taken Xiangshuili for cions, Shanli and Xiangshuili for rootstock, the survival rate of graft seedlings with root had higher survival rates than that without root. Added hormone to the media could improve the survival rate of micro-grafting plants, in the medium of MS+BA 1.0 mg/L+IBA 0.3 mg/L, the survival rate reached 86.7%.

结果］种子消毒处理及鲜果取种组培苗的成活率均较高，达75.0%以上；以香水梨和苹果梨为接穗，无根山梨为砧木时的嫁接苗成活率有显著差异，其中以香水梨为接穗的成活率较高；以香水梨为接穗，山梨和香水梨为砧木时，带根的材料嫁接时的成活率都显著高于无根嫁接苗的成活率；此外，添加植物生长调节物质可以有效提高嫁接成活率，在培养基MS+BA 1.0 mg/L+IBA 0.3 mg/L中嫁接苗的成活率最高，达86.7%。
