以不同番茄砧木为试材,研究了不同砧木嫁接对番茄产量、品质及南方根结线虫防治效果的影响。结果表明：6种砧木嫁接对番茄南方根结线虫的防治效果均在98.6%以上,高抗根结线虫。采用抗性砧木嫁接,番茄产量比自根对照提高15.4%～19.4%|砧木嫁接对接穗番茄果实可溶性蛋白、可溶性固形物和可滴定酸含量没有明显影响,但可溶性糖、VC、番茄红素和硝酸盐含量大多低于自根对照。从综合结果来看,采用抗性砧木果砧1号和特路丝进行嫁接栽培,对南方根结线虫具有很好的防治效果,对番茄品质影响较小,产量较高。 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

抗根结线虫砧木嫁接对番茄生长及产量的影响 总被引：15，自引：3，他引：15
番茄是我国保护地栽培的主要蔬菜之一。但由于多年的连作，导致枯萎病、根结线虫病等土传病害越来越严重，严重制约了保护地蔬菜的发展。Morra L．等研究表明，利用抗性砧木嫁接可以替代土壤熏蒸剂，控制根结线虫病和黄萎病，提高作物产量。还可以有效地防止土传病害的发生，克服作物的连作障碍，提高产量，减少农药施用量，有利于无公害生产。我国目前所用嫁接砧木大多为抗枯萎病、青枯病，而抗根结线虫病的砧木很少。笔者从意大利引进的番茄抗性砧木SIS-1，对根结线虫病有明显的控制效果，本试验以该砧木为试材，研究嫁接对番茄生长及产量的影响，以期为抗根结线虫病番茄砧木的引进与应用提供参考。 相似文献

嫁接番茄抗根结线虫砧木筛选及抗性研究 总被引：7，自引：3，他引：7
通过盆栽番茄自根苗和嫁接苗接种南方根结线虫（Meloidogyne incognita）二龄幼虫的试验,观察了接种后不同嫁接苗和自根苗对根结线虫的感染情况与抵御能力。结果表明：以北农茄砧与粘毛茄为砧木,彩虹101为接穗,嫁接后植株对根结线虫的抗性增强,可以达到免疫的程度。通过根系石蜡切片观察,根结线虫二龄幼虫不能侵染两种砧木的根系,因此不能形成根结;但接穗自根苗根系感染根结线虫,并在虫体周围形成巨型细胞。接种根结线虫刺激了保护酶系统的协调反应,对根结线虫抗性强的砧木嫁接苗的保护酶活性也较高 相似文献

嫁接对番茄产量、品质及耐盐性影响的综合评价 总被引：5，自引：0，他引：5
以‘佳西娜74-112’番茄自根嫁接植株及其与8种砧木嫁接植株为试材,研究盐胁迫下不同砧木对番茄生长、产量、品质、钾钠离子吸收与分配、光合作用等的影响,采用隶属函数法进行综合评价。结果表明,虽然盐胁迫降低了生长势和产量,但却显著提高了果实品质。嫁接植株生长势、产量、品质和耐盐性因砧木不同而显著不同。采用‘西方番茄砧木’嫁接进行耐盐栽培,比对照条件下自根嫁接番茄产量降低32.3%,但比盐胁迫栽培的自根嫁接番茄产量提高37.7%,且对果实品质的负面影响相对较小,表现出最强的综合优势。采用隶属函数法将多项指标进行综合排序,提出了一套可应用于番茄耐盐砧木筛选的分析流程,有望为盐碱地土壤的综合开发利用提供参考。 相似文献

SummaryHeirloom tomatoes (Solanum lycopersicum L.) such as ‘Cuore di Bue’ are highly appreciated by consumers for their outstanding quality and flavour. Nowadays, they are often grafted onto vigorous rootstocks in order to overcome several soil-borne diseases. The present study was conducted in 2007 and 2008 in Southern Italy. Plants of ‘Cuore di Bue’, an heirloom ‘oxheart’ tomato, were grown in a greenhouse either as non-grafted plants, or grafted onto two inter-specific (S. lycopersicum S. habrochaites) rootstocks (‘Beaufort F1’ and ‘Maxifort F1’) in order to evaluate their effects on vegetative growth, marketable yield, fruit quality, and the sensory properties of ‘Cuore di Bue’ tomato fruit. Growth analysis revealed that ‘Maxifort F1’ enhanced plant growth, particularly in terms of leaf area and leaf fresh weight. Grafted plants had higher leaf area ratios (by 13%) and higher leaf dry weight fractions (by 18%) compared to non-grafted ‘Cuore di Bue’ plants. Marketable yields increased by 20 – 25% in grafted plants in both years. However, total soluble solids (TSS) contents, titratable acidity (TA), and TSS/TA ratios were not significantly affected by grafting.Vitamin C contents decreased by 14 – 20% in both years in the fruit of plants grafted onto either rootstock. The sensory profiles of fruit were not modified by grafting, although taste panelists expressed a higher preference for purchasing fruit from plants grafted onto ‘Maxifort F1’. These results confirm that, when using the appropriate rootstock/scion combination, grafting can improve plant growth and the marketable yield of heirloom tomato fruit without reducing the sensory quality of the fruit or its biochemical parameters. However, grafting can reduce vitamin C contents and, thus, nutritional quality. 相似文献

The possibility of applying grafting to improve fruit quality has been scarcely investigated. Different shoot tomato (Solanum lycopersicum) genotypes were grafted onto distinctly-different tomato rootstocks and the effect of the rootstock on two important fruit quality parameters, soluble solids content (SSC) and titratable acidity (TA), was studied under both non-saline and saline conditions. Increased SSC and TA in fruits from grafted plants grown under saline conditions were observed on different grafting combinations. One of these rootstocks (cv. Radja) was able to induce increases in both fruit yield and fruit quality traits of the scion. When recombinant inbred lines (RILs) from the crossing of the cultivated tomato and wild tomato (Solanum cheesmaniae) were tested as rootstocks, using the commercial hybrid ‘Boludo’ as scion, the rootstock also improved SSC and TA when grafted plants were grown under non-saline conditions. On the whole, these results show the effectiveness of grafting with respect to upgrading of fruit quality in tomato, which is of great importance as grafting is a rapid and efficient alternative to achieve this goal. 相似文献
