The present work investigates the interactions between soil content, rootstock, and scion by focusing on the effects of roostocks and nitrogen supply on grape berry content. Scions of Cabernet Sauvignon (CS) and Pinot Noir (PN) varieties were grafted either on Riparia Gloire de Montpellier (RGM) or 110 Richter (110R) rootstock. The 4 rooststock/scion combinations were fertilized with 3 differen...

BACKGROUND AND AIMS Despite the widespread use of dwarfing rootstocks in the fruit-tree industry, their impact on tree architectural development and possible role in the within-tree balance between growth and flowering are still poorly understood, in particular during the early years of growth. The present study addressed this question in apple trees, through a detailed analysis of shoot popula...

the current experiment was carried out to evaluate qualitative and quantitativeof three melons (cucumis melo gp. ameri) accssions named zardjalal, ananasi and khanoti. the experiment was conducted in a randomized complete block design (rcbd) with 16 treatments and three replications at research field of jahad-e-daneshgahi, campus of agriculture and natural resources, university of tehran. five ...

The majority of the citriculture in Brazil is located in the state of São Paulo, with a total production area of 700,000 ha. Trees are grafted mostly on ‘Rangpur’ lime (RL; Citrus limonia Osbeck) rootstock. Despite its good horticultural performance, use of other rootstocks has increased with the search for disease-tolerant varieties to improve grove productivity and longevity. Furthermore, the...

In this study, a multivariate analysis combined with near-infrared (NIR) spectroscopy was employed to classify intact grape berries based on the rootstock x cover crops combination. NIR spectra were collected in diffuse reflection mode using TANGO FT-NIR spectrometer (Bruker, Germany) 8 cm−1 resolution and 64 scans wave number range of 4000–10,000 cm−1. The chemometric analyses performed statis...

tolerance of two apple rootstocks (gami and m26) was evaluated at different concentrations of sodium chloride in vitro conditions. micro plants grown under ms medium culture were transferred to knoudson–c culture medium devoid of na and cl ions. concentrations of nacl in the knoudson-c culture medium were 0, 20, 40, 60, 80 and 100 mm/l. six weeks after culturing, data were collected. the result...

Greenhouse-grown l-year-old sweet orange trees [Citrus sinensis (L.) Osbeck cv. Valencia] on cold-hardy trifoliate orange [Poncirus trifoliata (L.) Raf.] and cold-sensitive citron (C. medica L.) rootstocks were exposed to cold-acclimation conditions and freeze-tested at -6.7C for 4 hours in a temperature-programed walk-in freezer room. Nonhardened trees generally did not survive the freeze, whe...

Tall peas var. Alaska and dwarf peas var. Progress No. 9 were grafted onto their own roots or reciprocally grafted to determine the rootstock effect on the growth of the stem. In all cases the grafted stems grew the same as their ungrafted controls regardless of which rootstock they were grown on. When similarly grafted plants were supplied with gibberellic acid, good graft unions did not inhib...

Abstract The natural soil and climatic conditions of green manure crops are taken into account. It is important to choose the types suitable for growing them different purposes (as a main, repeated crop, animal feed, mulching), increase yield quality crops, achieve high biomass by using optimal seeding periods rootstock thicknesses. One urgent tasks carry out research in priority areas such as ...
