山葡萄生产主栽品种硬枝嫁接砧木筛选与嫁接树生产性能的研究 总被引：6，自引：0，他引：6
山葡萄生产主栽品种左山一、双红、双优和左优红、用“贝达”做砧木硬枝劈接亲和力、生根率、移栽苗圃地成活率和成苗率高。出圃苗木根系大于自根扦插苗木,用于生产建园表现生长和树体成型快、比同品种硬枝“扦插树”提早一年进入盛果期。上述品种2～6年生“贝达”嫁接树的公顷产量比对照平均增产20．8％、有良好的生产性能和遗传稳定性。上述品种与“公酿一号”硬枝嫁接、表现接穗与砧木亲和力差、生根和成苗率低、生产建园开花株率和产量低、3～4年生树嫁接树出现满树开花坐果少、5～6年生树出现大量死亡。左山一和双红互做砧穗、左优红做接稳、左山一和双红做砧木硬枝嫁接的催根幼苗表现为“假活”、不能育出苗木。 相似文献

Optimum conditions for rooting hardwood cuttings of several plum rootstocks have been determined with respect to season of cutting collection, the thickness of shoot and the part of the shoot used as the cutting, the concentration of rooting hormone applied to the base of the cutting and the basal temperature in the rooting medium.Rooting occurred most readily during autumn and again in late winter and spring. Cuttings made from “thin” shoots generally rooted more readily than those from “thick” ones but the position along the shoot from which the cutting was made was usually unimportant.Some clones, including Myrobalan B and St. Julien A, responded to increasing concentrations of 4(indolyl-3) butyric acid (IBA) to an optimum at 5,000 p.p.m. and to increasing bottom heat to about 20° C. Others, including Brompton and Pershore, were relatively unresponsive to both of these factors under the conditions of these experiments. 相似文献

从美国引进的枳柚4475、枳橙卡里佐、特洛亚、尤马4种柑桔砧木,经测定对主要的柑桔病毒病有一定的抗性,无病毒。使用其嫩枝,从茎尖向下截成5cm长两段,剪去下部刺、叶,浸入不同的激素溶液中2小时,在玻璃温室内扦插,结果表:1.不同品种生根能力不同,以枳柚4475发根最好,卡里佐、特洛亚枳橙次之,尤马枳橙生根能力最差。生根难易与植株长势一致。2.200ppmNAA、200ppmIBA、200ppm2.4—D浸插条基部2小时,对生根有显著作用,枳柚4475经IBA处理生根率达84.3％,对照为55.0％。3个枳橙品种以2.4—D处理为佳,提高生根率20％左右。3.枝条下段用作插穗,生根能力显著强于上段,说明插穗达到一定成熟度,积累营养物质,有利生根。4.一定的高湿,适当的温度是促使扦插成功的重要因素。夏季扦插嫩枝应降温,注意土壤消毒。 相似文献

不同葡萄砧穗组合根系构型研究 总被引：9，自引：0，他引：9
为探讨砧木根系组成的差异,以田间生长的6种葡萄嫁接植株为试材,挖根测定不同砧穗组合的根系构型,结果表明,以1103P为砧木的根系为深根性,3个品种组合分支角度为20°～40°,根系垂直分布为0～80cm土层,其中以20～40cm土层根量最大;而SO4砧木的根系为浅根性,分支角度为70°～90°,水平延伸为主,根系58.7%～67.5%集中分布于0～20cm土层内,60cm以下土层没有根系。地上部嫁接品种对同一砧木的根构型,特别是根系分布和根系数量有一定影响,但对分支角度影响不大。均以1103P为砧木,黑乌拉的根系分布深于桑乔维赛和法国兰;以SO4为砧木,维帝朝的表层根系明显多于波斯克,而桑乔维赛的根系数量明显少于维帝朝和波斯克。由此可见,品种对砧木有一定的反馈调节作用,但2种砧木根系构型差异明显,生产上应该根据生态条件选择深根或浅根性砧木。 相似文献

In vitro root development of micropropagated M26 apple rootstocks was promoted on low-nutrient Murashige and Skoog (MS)-type media. The most prolific rooting was obtained by lowering the sucrose concentration to 1% and the macronutrients to a quarter strength in the rooting medium, but this increased root development did not improve plant establishment. Although in vitro rooting on standard MS rooting medium increased during the 6-week culture period, highest plant establishment was obtained from 3-week cultures with relatively little root development at the time of planting. Therefore, these procedures which enhanced in vitro rooting were of no advantage in a propagation program. Greater than 80% plant establishment was obtained by substituting the in vitro rooting stage with rooting in mist. Shoot explants, which were dipped in commercial rooting powder, were established in a peat:sand (1:1) sub-strate in the mist frame. This procedure would reduce labour and cost of commercial micropropagation programs. 相似文献

The rooting ability of one-node leafy cuttings of Eucalyptus globulus decreased rapidly with distance from the (decapitated) apical node. The young and immature leaves close to the shoot apex usually promoted rooting whereas the apex itself had little effect or was detrimental. In apical cuttings with an equivalent complement of leaves, increasing stem volume (and woodiness at the base of the cutting) slightly reduced rooting. The swelling of the stem at the base of shoots from coppice or potted plants also reduced rooting when present at the base of the cutting, whereas the inclusion of the root/shoot junction of seedlings promoted rooting. Cuttings from small seedlings rooted well and the roots sometimes emerged directly from the stem, whereas in non-seedling cuttings, roots nearly always arose from callus. The survival of cuttings in the propagation environment varied between trials. In apical cuttings with the same leaf complement, survival tended to increase with woodiness at the base of the cutting, but in contiguous one-node cuttings this tendency was overcome by the leaves, the soft apical nodes surviving better than the more proximal woodier nodes. 相似文献
