selection and use of tolerant grapevine as rootstock or own-rooted vines and finding indexes for screening of resistant genotypes have especial importance. to identify the salt tolerant grapevine genotypes, effects of nacl concentrations (0, 50, 100 and 150 mm) on root length, root and shoot dry weight, prolin, total soluble solid, rwc, level of salt injury, leaf concentration of k, na, cl and ...

ABSTRACT In a field trial in soil infested with Verticillium dahliae, we compared the yield, growth, incidence of symptoms of Verticillium wilt, and mortality of two interspecific hybrid pistachio tree rootstocks (UCBI and PGII) with the standard rootstocks: the V. dahliae-resistant and susceptible Pistacia integerrima and P. atlantica, respectively. After 10 years, the trees were destructively...

Suitable rootstock enhances apple tree resilience. In 2021, we studied “Buckeye Gala” ( Malus domestica var. Buckeye Gala") on nine rootstocks with contrasting vigor in NS and BC, Canada. Rootstock effects vigor, yield, midday stem water potential were significant BC. After sustained heat events, the large-dwarfing Geneva 935, 4814, 969 had lower ratio of sunburn fruits, resulting higher projec...

Cryopreservation of vegetative winter buds is an alternative method to preserving plant species in the field. In this method, nodal sections of scionwood are stored in liquid nitrogen vapor. Cryopreservation of the vegetative dormant winter buds involves low maintenance costs and virtually eliminates the risk of germplasm loss. At the NCGRP, this method is routinely used to preserve Malus sp. (...
