双砧木嫁接对西瓜生长及果实品质的影响 总被引:2,自引:0,他引:2
《中国瓜菜》2017,(7):13-16
为了探索出一条改善嫁接西瓜品质的简便可行途径,笔者利用生产上常用的葫芦砧和南瓜砧采用贴接法进行双砧木嫁接,研究了双砧木嫁接、常规单砧木嫁接和自根嫁接西瓜生长与果实品质的差异。结果表明,采用贴接法进行的双砧木嫁接可显著提高西瓜植株主蔓长度、茎粗,双砧木嫁接西瓜的果实单瓜质量最高(1.34 kg),分别比自根嫁接(CK)及葫芦砧、南瓜砧嫁接西瓜增加91.43%、81.08%、50.56%,并可提高果实的可溶性糖含量、维生素C含量、番茄红素含量和游离氨基酸总量。双砧木嫁接能够综合单砧木的优势,增强嫁接西瓜生长势,显著增加嫁接西瓜单瓜质量,明显提高果实品质。 相似文献

以线虫绝3号为砧木进行不同番茄嫁接方法试验研究.研究结果表明,番茄采用靠接法、切接法、插接法嫁接成活率分别为94.5%,91.0%.88.5%.采用插接法嫁接,分别研究砧木保留1,2,3,4,5片真叶时对嫁接成活率的影响.试验结果表明,砧木保留叶片数不同对嫁接成活率有一定影响,以保留3片真叶嫁接成活率最高.达到94%:1片真叶的嫁接成活率最低,仅为45%.砧木留真叶数不同,嫁接后各处理之间番茄的生育状况及产量无显著差异,但均比施药的自根苗处理显著增产.综合考虑,番茄嫁接以采用插接法,砧木保留2~3片真叶最为理想. 相似文献

苦瓜(Momordica charantia L.)是一种常见、风味独特的蔬菜,由于它的医疗和保健功能[1,2,3]而得到了人们的喜爱.随着蔬菜基地的连作,苦瓜枯萎病越来越重,严重地影响了苦瓜的生产和发展.防治苦瓜枯萎病最好是采用抗病品种,但在现有市面上缺乏较好的抗病品种的情况下,采用嫁接技术,把不抗病的品种嫁接到抗病性强的砧木上则是防治苦瓜枯萎病的一条简单而行之有效的途径.传统的做法是一苗苦瓜嫁接一棵砧木的方式,但现在种子价格较贵而且在嫁接过程中要承担百分之几的死亡率,所以本次试验探索了用优良的苦瓜腋芽作接穗,进行一苗苦瓜嫁接多棵砧木的嫁接方法的可行性. 相似文献

为探明番茄嫁接后砧木、接穗残株再生性及再利用的可行性,以番茄砧木品种久绿787和接穗品种佳红4号为试材,研究砧木、接穗残株再生苗的生长发育进程,比较再生苗与初次嫁接苗的愈合情况和生长指标。结果表明:番茄嫁接后砧木残株可扦插再生、接穗残株可腋芽再生形成完整的幼苗,与播种形成幼苗相比,砧木残株扦插苗和接穗残株腋芽再生苗达到嫁接苗龄的时间可缩短16 d;利用砧木、接穗残株嫁接,嫁接苗成活率、接合力、输导能力及后期生长参数与初次嫁接苗差异不显著。通过嫁接苗培养成本比较,利用砧/穗残株进行嫁接的幼苗生产成本明显低于初次嫁接苗,按每万株嫁接苗计,可节约成本875.5元。说明番茄嫁接后砧/穗残株可以嫁接再利用,并可明显提高经济效益。 相似文献

A successful micrografting technique in cashew was developed using in vitro germinated seedlings as rootstocks and axenic shoot cultures (shoot-tip and nodal cultures) established from mature tree source as microscions. In vitro germinated seedlings, which emerged 20–25 days after inoculation on absorbent cotton, were decapitated and used as rootstock. Mature tree explants initiated on hormone-free Murashige and Skoog [Physiol. Plant. 15 (1962) 473] (MS) modified medium were made into scion of 3–15 mm length for grafting. Micrografts could be easily cultured on hormone-free liquid half-MS medium and were potted out after 10–12 weeks of culture growth. Grafting success was dependent on the method of grafting and size of the scion. Shoot-tip grafting and side grafting were equally successful (79.5–100%). Length of scion shoot had significant effect on micrografting success. Graft success was high (79.5%) when the scion length was >5 mm and it was less (0.5%) when size of scion was small (3–5 mm). Scion presoaked in either water or 0.01% ascorbic acid and 0.015% citric acid (1:1) reduced phenolic browning and drying of scion. Micrografting techniques standardized could be used for rejuvenation of shoot explants of mature tree. 相似文献

分别以黑籽丝瓜、黑籽南瓜、白籽丝瓜为砧木,与兴合苦瓜进行嫁接,研究比较了3种砧木对苦瓜嫁接亲和力、生长发育、果实商品性、产量及抗逆性的影响。试验结果表明,3种砧木与苦瓜接穗亲和力较强,均能达到95%及以上,其中以白籽丝瓜嫁接后,苦瓜生长势强、抗病及抗旱性好、商品性状最优、产量最高。综合比较,白籽丝瓜是苦瓜嫁接的理想砧木,适合在生产中推广应用。 相似文献

A method was developed for quick propagation of roses under conditions prevailing in The Netherlands, based on cutting and grafting in one action and called “stenting” (to stent), being a contraction of the dutch words “stekken” (to strike a cutting) and “enten” (to graft). A piece of stem of the cultivar with one leaf and a dormant bud is grafted on a single internode of the rootstock. Formation of the graft union and of adventitious roots occur simultaneously, resulting in a complete plant in 3 weeks.Absence of buds on the rootstock is essential to diminish wild suckering. Factors influencing the percentage of successful stentlings were investigated. With R. chinensis ‘Indica Major’ as a rootstock, the best results were obtained with mature internodes 6–8 mm in diameter after application of 5000 mg 1?1 IBA. Pre-treatment of the rootstock internodes by application of IBA and storage at 4° C for 3 weeks improved rooting. Comparison of grafting by hand and by machine showed that machine-grafting offers good possibilities.The influence of the cultivar, after cutting or stenting, on root-formation and root-growth was studied. Grafting on seedling rootstocks (bench-grafting) and stenting proved to give similar results. In the first year after stenting, R. chinensis ‘Indica Major’ was a better rootstock for the cultivar ‘Cocktail 80’ than R. canina ‘Inermis’, while ‘Inermis’ was better for ‘Motrea’.Rose culture can be improved by using cultivars stented on a convenient rootstock. Stenting can be applied around the year, is ideal for screening new scion/stock combinations and to investigate the interaction between shoots and roots. 相似文献

利用观赏茄子的一个分枝作砧木,观赏番茄作接穗;观赏番茄的一个侧枝作砧木,观赏茄子作接穗进行观赏番茄观赏茄子双向嫁接研究。试验结果表明,观赏番茄作接穗时嫁接成活率明显高于观赏茄子作接穗时的嫁接成活率,能否嫁接成活与嫁接时的砧木、接穗的茎粗有一定的关系,本试验中观赏番茄、观赏茄子茎粗在0.5 cm时嫁接成活率最高。 相似文献

为了明确茄子嫁接后砧木、接穗残株的再生进程及再次嫁接利用的可行性,以茄砧1号、园杂471为砧木和接穗品种,研究砧木、接穗残株再生苗的生长发育进程,并比较残株再生苗嫁接与初次嫁接苗的愈合情况和生长指标。结果表明:茄子嫁接后砧木残株扦插再生、接穗残株腋芽再生30 d左右均可形成健壮的幼苗,植株茎粗可达2.5 mm左右,与播种育苗相比,砧木、接穗分别缩短育苗时间约45、10 d;利用砧木、接穗残株进行嫁接,嫁接苗成活率、木质部输导能力、砧/穗接合力及35 d嫁接苗净生长量与初次嫁接苗无显著差异。茄子残株嫁接苗砧木与接穗培养成本明显低于初次嫁接苗,按万株嫁接苗计,可节约生产成本696.4元。综上,茄子嫁接后砧/穗残株可以嫁接再利用,并可提高经济效益。 相似文献
