In modern pear cultivation, clonal quince and pear rootstocks are preferred because they are easy to maintain and harvest. Also, they form dwarf plants and improve fruit quality compared to pear seedling rootstocks. However, graft incompatibility can be involved between different species or genera. The aim of the study was to determine the graft compatibility of the ‘Deveci’ and ‘Williams’ pear cultivars with different pear and quince rootstocks by carbohydrate analysis. Carbohydrate accumulation in the graft union was also observed with iodized potassium iodide (KI) staining. In terms of rootstocks, there were no differences in starch and carbohydrate content, but statistically differences were found in sugar contents. Significant differences were also found between cultivars and graft union in terms of the examined traits. Sugar content was highest in OHxF 333 and lowest in seedling rootstocks. There were no statistical differences in the starch content between the graft unions of the ‘Deveci’ cultivar, while starch accumulation was higher above the graft union than below and graft union in the ‘Williams’ cultivar grafted on the quince rootstock. In the study, it was determined that there were higher carbohydrate accumulation in the scion and graft union than below the graft union in ‘Williams’ grafted quince rootstocks, which was also confirmed by staining with KI. As a result of the study, it was concluded that carbohydrate accumulation analysis can be used to determine the graft compatibility of the pear cultivars with the different quince and pear rootstocks.

以川鄂两地金弹子为接穗,采取劈接、腹接、靠接3种嫁接方法对金弹子老桩进行高接换头和造型改造技术试验.结果表明:3种嫁接方法的成活率均高达96％或以上；同期枝条生长量以劈接最大,从后期枝片茂盛情况来看则以腹接为好,所以在盆景造型过程中,根据树桩上枝位选择不同接法,是金弹子盆景快速成型的一条捷径. 相似文献

为了探讨采用哪种嫁接方法和包缚方法使山楂高接的成活率最高,从而提高当前生产上山楂高接换种的成功率,进行了劈接、单芽枝腹接和插皮接三种方法的对比,结果山楂高接成活率无显著差异,在生产上都可应用。但在嫁接时期上有所不同,劈接宜早,一般从3月下旬至砧枝离皮,插皮接在离皮后进行,单芽枝腹接可在整个嫁接时期(3月下旬至4月下旬)。高接时所用五种包缚方法中,以“塑料薄膜绕嫁接部位卷成筒状,其内村纸再袋入湿土上口扎严”和“蜡封接穗用塑料薄膜条只包缚接口”两种方法.成活率最高,可在生产上推广应用。山楂高接适用的方法和包缚的方法@… 相似文献

云南野生川梨资源丰富,山区及半山区农民常就地嫁接建成梨园。多采用劈接法嫁接,接穗一般留芽 ２～３个,长 ７～１０ｃｍ。但由于人们常上山打柴、割草及放牧,较长而缺乏保护的接穗常被碰撞,造成嫁接成活率低。为此,笔者进行了不同嫁接方法的比较。试验于１９９８年２月上旬在大理市下关镇进行,供试梨品种为砀山酥梨。设多芽劈接、单芽劈接、单芽切接、单芽腹接及嵌芽接等５个处理。多芽劈接的接穗留芽２～３个,长７～１０ｃｍ。单芽劈接、单芽切接和单芽腹接的接穗长３～４ｃｍ。每处理嫁接３０株适龄川梨,每株接１枝接穗。为防止… 相似文献

Faced with new challenges, such as emerging diseases, shortening of orchard longevity, and larger social and environmental demands from consumers, practices such as rootstock diversification, irrigation and high density plantings have become relevant for the Brazilian citrus industry. This research had the objective to evaluate the performance of irrigated and non-irrigated ‘Tahiti’ lime trees grafted on 12 rootstocks and one interstock. Plots were distributed following a randomized block design, with four replicates and one plant per plot. Rootstocks influenced plant vigor, especially ‘Flying Dragon’ trifoliate, which reduced tree height by approximately 47% compared to the ‘Rangpur’ lime. Trees that were budded on more vigorous rootstocks showed higher yield when grown without irrigation than with irrigation. The ‘1646’ citradia and ‘Morton’ citrange rootstocks performed particularly well. On the other hand, the plants on less vigorous rootstocks showed better performance in terms of yield under irrigation than the same combinations without irrigation, especially those grafted on the tetraploid ‘Carrizo’ and ‘Troyer’ citranges, ‘Swingle’ citrumelo, ‘Davis A’ trifoliate and ‘Flying Dragon’ trifoliate. Plants budded on the ‘1708’ citradia had high yields under irrigated and non-irrigated conditions. The effect of interstock on plant vigor was dependent of rootstock. Interstocked plants on ‘Davis A’ trifoliate were higher than those without interstock. On the other hand, interstocked plants on Catania 2 ‘Volkamer’ lemon were less vigorous than those without interstock. 相似文献

We investigated the cause of defoliation in sweet pepper (Capsicum annuum L.) plants after grafting. Grafted plants of old-stage sweet pepper showed a higher defoliation rate than young-stage grafted plants. Old-stage grafted plants had lower stomatal resistance and water potential than young-stage plants, and showed poorly developed xylem connections at the graft site. Foliar application of abscisic acid (ABA) to the grafted plants increased stomatal resistance and water potential, decreased the defoliation rate, and promoted graft take among old-stage plants. Our results indicated that low stomatal resistance under low humidity induces water stress, defoliation, and low survival rate in old-stage grafted sweet pepper plants. ABA treatment increased stomatal resistance, water potential, and survival rate, and decreased the defoliation rate among old-stage sweet pepper plants. 相似文献

嫁接辣椒对青枯病的抗性及其与渗透调节物质的关系 总被引：3，自引：0，他引：3
青枯病是当前设施辣椒主要的土传病害之一。为了选择抗性砧木和探讨嫁接辣椒的抗病机理,通过人工接种青枯病原菌,分析了不同辣椒品种砧木的发病率和病情指数变化,结果表明：‘富根卫士’（简称‘卫士’）发病晚,发病率低,病情指数最小,抗病性最强。以‘卫士’辣椒为砧木,以‘新丰2号’为接穗进行嫁接,以接穗自根嫁接为对照,研究其发病率、病情指数和渗透调节物质的变化。结果表明：嫁接植株的发病率和病情指数显著低于对照,接种20 d时,嫁接植株发病率和病情指数分别比对照低33%和43%。接种前嫁接的植株根系和叶片的含水量、水势、渗透势均低于对照,束缚水/自由水比值、可溶性糖及脯氨酸含量均高于对照。接种后,辣椒根系和叶片的含水量、水势、渗透势均逐渐降低,束缚水/自由水比值逐渐升高,可溶性糖和脯氨酸含量先升高后降低;与对照相比,嫁接植株根系和叶片的含水量、水势、渗透势的降低幅度及束缚水/自由水比值升高幅度明显较小,可溶性糖和脯氨酸含量显著增加。研究结果表明嫁接可显著提高辣椒青枯病的抗性,其抗病机理与渗透调节能力增强有关。 相似文献

灌水量对温室自根与嫁接黄瓜根系分布及水分利用效率的影响 总被引：5，自引：0，他引：5
为探求黄瓜适宜的节水灌溉方式,以温室栽培的黄瓜自根苗和嫁接苗为试验材料,设定每次灌水150、300和450 m3 · hm-2的不同灌水量,研究灌水量对黄瓜根系分布、商品瓜产量和水分利用效率的影响。结果表明,与常规灌水量对照（每次450 m3 · hm-2）相比,适度减少灌水量,在多数情况下不会显著影响黄瓜根系生长、垂直分布与水分利用,每次150 m3· hm-2的灌水量对自根与嫁接黄瓜的产量无显著影响,水分利用效率显著提高。每次150 m3 · hm-2灌水量下,嫁接黄瓜的根系旺盛且粗壮,同时诱发了大量毛细根向土壤深层分布,使其产量显著高于自根黄瓜,因此在减量灌溉条件下,嫁接具有良好的促根节水丰产的效果。 相似文献
