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...

The lychee is, all over the world, considered as the “queen of the fruits” due to the delicacy of its appearance and flavor. Although it was only recently that it started to have economical importance in Brazil, the lychee is already calling the attention of numerous farmers, mainly those who cultivate citric fruits and/or sugarcane in the State of São Paulo, due to the constant and at the same...

Drought is one of the most prevalent limiting factors causing considerable losses in crop productivity, inflicting economic as well as nutritional insecurity. One of the greatest challenges faced by the scientific community in the next few years is to minimize the yield losses caused by drought. Drought resistance is a complex quantitative trait controlled by many genes. Thus, introgression of ...

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...

Over the last 20 years stone fruit rootstock development has begun shifting from seedling to clonal types, many of interspecific origin. Publicly funded breeding programs have produced most of these rootstocks due to the time, cost, and risk associated with their development; however, private industry is emerging as a significant contributor of many of the newer rootstocks. Particularly notewor...

In this study, ‘Xinli No. 3’, ‘Shengli rootstock’, ‘Shenli rootstock’ and ‘Shengzhen 1’ were used as rootstock, ‘Jinchun 39’ cucumber was scion to study the effects of different rootstock on yield quality grafted cucumber, select high suitable for grafting. Different affected survival rate, phenology, height plant, stem diameter, growth potential, Among them, rate is highest, relatively stronge...
