S u m m a r y : The response of 11 grapevine rootstock varieties to increasing salt concentrations (0, 50, 85, 120, 155 mMNaCI) was studied under in vitro and growth chamber conditions . The effect of salinity on the mortality of explants was compared with that of plantlets grown under growth chamber conditions and with data in literature on rootstock resistance under field conditions . In addi...

The grafting of fruits and vegetables influences fruit quality. The aim of the present work was to assess the effect of the rootstock and the scion on the antioxidant activity and the content in vitamin C, total phenols, lycopene and β-carotene of bell pepper. The cultivars Fascinato and Jeanette were used as scion and Terrano was used as rootstock. Four harvests in the production cycle of the ...

The rhizosphere is where crucial processes for the productivity of viticultural systems occur. composition bacterial communities associated with grapevines known to depend on plant genotype. However, genotype grafted differs between scion and rootstock; role each unclear. To untangle effect rootstock, rRNA (V4–V5 region 16S rRNA) extracted from grape varieties Riesling Mueller-Thurgau ungrafted...

introduction: all fruits that called citrus are from rutaceae family and aurantioideae subfamily. this subfamily have more than 33 different genus that only three of its genus (citrus, poncirus and fortunella) have economic aspects and in citrus producing country are important. it's reported that orange skin has a phenolic compounds which play a role in natural defense mechanism. also various c...

This study evaluated how the proportional area of natural habitat surrounding a vineyard (i.e. landscape diversity) worked in conjunction with crop vigor, cultivar and rootstock selection to influence biological control of the western grape leafhopper (Erythroneura elegantula Osborn). The key natural enemies of E. elegantula are Anagrus erythroneurae S. Trjapitzin & Chiappini and A. daanei Tria...

It is well known that rootstocks can have an effect on the vegetative growth and development of the tree; however, there has been no clear explanation about the physiological mechanism involved in this phenomenon. Evidence indicates that the rootstock effects on tree vegetative growth may be related to hydraulic limitations of the rootstock. The objective of these experiments was to investigate...

Grafting in species other than Arabidopsis has generated persuasive evidence for long-distance signals involved in many plant processes, including regulation of flowering time and shoot branching. Hitherto, such approaches in Arabidopsis have been hampered by the lack of suitable grafting techniques. Here, a range of micrografting methods for young Arabidopsis seedlings are described. The simpl...

Grafting is an easier and faster approach than plant breeding to take advantage of both existing resistant plants, especially wild cultivars, and high-bred cultivars. The aim of this study was to investigate the changes in leaf photosynthetic capacity of a hybrid eggplant Solanum melongena L., cv. Rima (R), widely used in Greece] when grafted on tomato rootstocks known for their resistance to n...

growth traits, yield and fruit quality in ‘synda’ tomato were compared with those in tomatoes grafted onto either ‘king kong’ rootstock or onto their own rootstocks, (trained as single or double stem), and at two fruit thinning levels, of: no thinning or thinned to five fruits per truss. the data related to crop growth rate (cgr), relative growth rate (rgr), net assimilation rate (nar), leaf ar...
