茄子不同砧木嫁接比较试验 总被引：1，自引：0，他引：1
以杭茄1号为接穗,以无刺托鲁巴姆、有刺托鲁巴姆等6种野生茄子为砧木进行嫁接,对其物候期、成熟期、植株生长、果实大小和旱期产量等方面进行比较.结果表明,0601、0603和0604三个砧木嫁接后茄子成熟期比杭茄1号自根苗延长1～2 d,但是0602、无刺托鲁巴姆和有刺托鲁巴姆为砧木的成熟期比杭茄1号自根苗延长34 d,28 d和27 d,杭茄1号嫁接后,株高、株幅和茎粗都因砧木品种不同发生了较为显著的变化,产量方面,除以0603和0604为砧木嫁接后在前期产量上低于杭茄1号自根苗外,其他品种前期产量均显著高于杭茄1号自根苗. 相似文献

试验以‘托鲁巴姆’为砧木,‘龙园棚茄1号’为接穗,在不同连作年限下嫁接对茄子黄萎病发病率和病情指数进行研究。结果表明:采用嫁接技术在不同连作年限下,能显著降低嫁接苗的发病率和病情指数。茄子生育的中后期,嫁接茄子的黄萎病发病率在3.57%~9.52%之间,病情指数在0.97~4.16之间,仅为自根苗发病率的14.03%,且随着连作年限增加,嫁接后发病率降低明显。 相似文献

嫁接对茄子根际土壤微生物和叶片硝酸还原酶的影响 总被引：3，自引：0，他引：3
以野生茄‘托鲁巴姆’ (Solanum torvum ) 为砧木, 茄子(S. m elongena) ‘西安绿茄’品种为接穗, 研究了嫁接茄根际土壤微生物生理类群和土壤水解酶活性及叶片硝酸还原酶活性的动态变化特点,分析了嫁接茄根际土壤微生物生理类群和土壤水解酶与叶片硝酸还原酶活性的关系, 探讨了嫁接提高茄子氮素转化和吸收与土壤生物活性的关系。结果表明: 嫁接茄根际土壤微生物生理类群和土壤水解酶活性均较自根茄有增加的趋势。但不同发育时期也有一定的变化。嫁接茄叶片硝酸还原酶活性随着生育均表现出逐渐增加的趋势, 且显著高于自根处理。嫁接茄的固氮菌、硝化细菌和脲酶与其叶片硝酸还原酶活性均呈显著或极显著正相关。总体上看, 嫁接显著增加了茄子根际土壤固氮菌、硝化细菌和脲酶活性, 嫁接茄株也表现出较高的硝酸还原酶活性。 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

We propose the utilization of eggplant (Solanum melongena L.) interspecific hybrids derived from crosses with closely related species as an approach for developing new improved rootstocks for eggplant. Here we investigate rootstock effects on fruit yield, apparent quality and proximate and mineral composition of S. melongena ‘Black Beauty’ (BB) scions grafted on interspecific hybrid rootstocks developed from crosses of S. melongena with Solanum incanum L. (SI × SM) and Solanum aethiopicum L. (SM × SA). The results are compared with non-grafted (BB control) and self-grafted (BB/BB) controls and with S. melongena ‘Black Beauty’ scions grafted onto Solanum torvum Sw. (STO) and Solanum macrocarpon L. (SMA) rootstocks. All treatments were grown in a soil naturally infested with root-knot nematodes (mostly Meloidogyne incognita (Kofoid and White) Chitwood). SI × SM and SM × SA interspecific hybrids had high germination (≥90%) and total graft success (100%). Contrary to what occurred with all other treatments, no plants from scions grafted onto these hybrid rootstocks died during the experiment. In particular, the SI × SM hybrid rootstock conferred the highest vigour to the scion, which resulted in the highest values for fruit earliness and early and total yield. Little difference was observed among treatments for apparent fruit quality traits, except for a greater fruit calyx length and prickliness of fruit grafted onto SMA rootstocks. A similar result was obtained for fruit composition where phenolics content was higher in fruit from plants grafted onto SMA rootstocks. Grafting eggplant onto interspecific eggplant hybrids, especially on the SI × SM hybrid, has proved advantageous for eggplant production, as the high vigour and good compatibility of the rootstock with scion results in improved early and total yield without negative effects on apparent fruit quality or composition. Interspecific hybrids represent an alternative to the commonly used STO rootstock, which is a wild species with irregular germination. 相似文献

SummarySix wild species of Eriobotrya were evaluated as rootstocks for domesticated loquat. Twelve-month-old seedlings of Oak leaf loquat (an Oak Leaf loquat ‘Zaozhong No. 6’ hybrid) and wild Fragrant loquat (E. fragrans Champ) had higher root-to-shoot fresh weight (FW) ratios than other wild species. When the domesticated loquat, ‘Zaozhong No. 6’, was grafted onto seedlings of six different wild loquat species, differences in compatibility were observed. Graft compatibility was lower for all combinations compared to ‘Zaozhong No. 6’ grafted onto domesticated loquat seedlings. When wild Henry loquat was used as a rootstock, delayed incompatibility was observed. Differences in soluble sugar contents (SSC) between scion and rootstock were observed, and there was a significant negative correlation between graft compatibility and the difference in SSC values. The influence of the rootstock on anatomical changes at the graft union were observed using a scanning electron microscope (SEM). Wild rootstocks also influenced scion growth, fruit bearing, and fruit quality. Graft combinations which used wild Fragrant loquat as the rootstock had increased cold tolerance and improved scion growth. Wild Fragrant loquat therefore appears to have value as a rootstock for domesticated loquat. 相似文献

抗南方根结线虫不同番茄砧木田间综合评价 总被引：5，自引：0，他引：5
选用9份番茄砧木与中杂9号番茄嫁接,在日光温室内比较了其对植株抗性、生长发育及果实品质等的影响。结果表明:041-373、031D158、Genaros、Baofa009和Trs-401砧木苗期及田间对南方根结线虫的抗性鉴定均表现为抗病;与中杂9号自根苗对照相比,各砧木嫁接对植株长势、产量、单果质量等均无显著影响;不同砧木材料对番茄果实VC含量影响不明显,但可以影响果实可溶性蛋白、可溶性糖含量及糖酸比,其中Eldorado砧木嫁接可显著降低果实可溶性糖含量及糖酸比,而041-373及Trs-401砧木嫁接则可显著提高果实可溶性糖含量及糖酸比。综合考虑不同砧木抗性表现及对果实品质等的影响,认为生产上可以将041-373、031D158、Genaros、Baofa009、Trs-401等5份砧木材料作为抗南方根结线虫砧木用于研究与示范。 相似文献

SummaryMelon (Cucumis melo L.) ‘Arava’ was grafted onto 22 experimental Cucurbita rootstocks including intra- or interspecific hybrids to examine scion-rootstock compatibility and to correlate plant performance under greenhouse and field conditions. The commercial Cucurbita ‘TZ-148’ rootstock and non-grafted plants were used as controls. Numbers of leaves, stem length and plant fresh weights were recorded three weeks after planting. Vegetative growth of the grafted plants varied markedly, indicating differences in compatibility between the scion and rootstocks. A positive correlation was found between number of leaves, stem length and fresh weight of melon plants. No significant advantage in vegetative growth was found in melons grafted onto intra- or interspecific hybrid rootstocks. Stem diameter and number of vascular bundles of the rootstock did not correlate with scion plant fresh weight. Twelve selected rootstocks out of the 22 tested were grown in the field during the spring and autumn, to determine if there is an association between the plant performance in the greenhouse and fruit yield under field conditions. Positive and significant correlations were found between greenhouse growth parameters and fruit yield under field conditions. It is suggested that testing grafted melons under greenhouse conditions could be a useful tool for preliminary testing of scion-rootstock compatibility. 相似文献
