Vegetable produces middle in facilities, eggplant (Solanum melongena L) is that one of importantvegetable kind, lower facilities condition eggplant cropping area increase by year by year. Crop rotation isrestricted but because of facilities inner childbirth, soil biography disease such as eggplant blight,verticillium wilt is in recent years more and more grave. The verticillium wilt (Verticillium wilt) is tothreaten one of the important disease that eggplant produces, but reduces eggplant's output and quality by awide margin. Adopt disease-resistant stock to carry out eggplant graft, taking as an example reach thepurpose lightening disease, increasing both production and income, synergy, graft to be that preventionand cure eggplant is at present local one of the most effective biography disease measure. Capital is studiedadopt wedge connection, wild eggplant to surpass Tuolubam, Tuolubam, to there be no thorn hemlock, toirritate eggplant, Tuotuosijia, red eggplant and cultigen Shen eggplant being stock on the first, make use ofShen eggplant to do a scion on the first, the eggplant being in progress is graft cropping effect anddisease-resistant research increasing the production of aspect's, to discuss the basis making use of thetheory providing science in grafting disease-resistant eggplant high yield physiology mechanism, being tograft a technology giving birth to a child in eggplant. Test result indicates capital:Grafts may obvious the disease incidence rate which reduces eggplant The verticillium wilt to get sick,reduces its condition index. Grafts the matchrate to be allowed to respond in the growth process the stockandscion's coordination, in grafts in the match rate scion to have to behigher than the wild eggplant stockfrom the seedling of stocks. By 6 kind of stocks eggplants and scion oneself each processing whichgraft forthe stock, it grafts the survival rate all to surpass 90ï¼….You Yichao holds tolubamu and the request holdseggplant the stock grafts to demonstrate extremely high grafted the affinity, grafted the survival rate toachieve above 98ï¼…, explained it had very well with the scion grafting. Grafts has the too big change by nomeans to the eggplant quality; At the same time, enhanced the adult plant fresh growing trend,lengthenedthe recovery time, increased its output.The initial period of Grafting, the scions and the stocks lose contact, along with marries thecomposition plane to produce the insulating layer, the O2- production rate and the H2O2content of stockgrafting compares the scion to have the enhancement from stocks and seedling, causes the evening whichits insulating layer vanishes, the stock and scion bridge to link up also late, thus causes to graft heals thetime to be late to the scion from stocks and the seedling. This experiment also discovered, after grafting the9-12th day, forms when links up the scion and the stock the bridge, draws back meets the connection placeSOD activity, the CAT activity, several Ding nature enzyme activity, beta -1,3- glucosanenzymes activityis higher than other spots, further explained these enzymes and the promotion graft the connection in thevascular tissue fast to heal the importance.Through the experimental analysis, after meets the fungus regardless is the stock graft the body or thescion from offspring, from stock and the seedling in N content, the total water content, the O2- productionrate and the H2O2 content has the drop, but in P, K, Ca, the Mg content, the free water/bound water ratio,the SOD activity, the CAT activity, several Ding nature enzyme activity and beta -1,3-glucosanenzymeactivity actually depends on the stock the disease-resistant strong and the weak to have the varying degree the enhancement or the increase, And plants to the stock and plant's root, stem dissection structureobservation discovery, stock's drive pipe quantity many, drive pipe diameter big, drive pipe tube wallthickness, crystal cell quantity many, wooden parenchyma cell wall thickness, but plants is exactly opposite.From the above elaboration and the experimental analysis we can see, this time each processingcomparatively compares in the biology character and the internal structure has very strong disease-resistant.
