The cultivar and rootstock effect on iron chlorosis were studied. The results revealed significant differences among peach cultivars and rootstocks in mineral content. Seasonal changes were also found in the macroand micronutrient content of leaves of peach cultivars and rootstocks. The rootstock St. Julien 655/2 was found to be efficient in K, P, Zn, Fe, Cu absorption and better than seedling ...

In order to establish an endomycorrhizal symbiosis on micropropagated plants and to evaluate its effect on plant growth and survival, three rootstocks belonging to the Prunus genus were used: M51 (P. dulcis), GF677 (P. persica×P. dulcis) and cv Citation (P. domestica×P. persica). The plants were micropropagated and in vitro rooted. Spores of Glomus mosseae (LMSS) and Scutellospora calospora (SC...

Drought stress is the most important factor limiting successful production of agricultural crops worldwide. The response some almond cultivars grafted on GF677 rootstock was studied to drought at a research greenhouse in Horticultural Science Research Institute Karaj, Iran, 2016-2017 growing season. plant materials included 12 (Prunus dulcis Mill.) genotypes/cultivars, including ‘Sh10’, ‘Saba’,...

Rhizobium radiobacter is a significant causal agent that ranks among the top ten bacteria of molecular plant pathology in world, has largest range hosts pathogenic bacteria, and limits production leads to economic losses agriculture. The distinctive feature from other Ti plasmid, extrachromosomal structure present all virulent types. In this study, virulence five R. isolates (1A, 1B, 2A, 2B RK ...

in order to evaluate tolerance of four prunus rootstocks to fe-deficiency-induced chlorosis,  an experiment was carried out in bu-ali sina university in 2012 using a rcbd design with four replications. four rootstocks were used, including gf677, gn15, bitter almond and peach and nutritional treatments were: hoagland solution without fe (ph = 6), hoagland solution containing 90µm fe as control (...

boron (b) toxicity is an important disorder that can limit plant growth in arid and semi-arid environments. it has been proven that use of tolerant rootstocks impede b uptake or transport to the aerial portions of plants. this may alleviate b toxicity in the scion, consequently improves the tolerance to excess b in the root zone. an experiment was conducted to find the effects of b toxicity on ...

We develop an approach to utilize anisotropic metamaterials to solve one of the fundamental problems of modern plasmonics--parasitic scattering of surface waves into free-space modes, opening the road to truly two-dimensional plasmonic optics. We illustrate the developed formalism on the examples of plasmonic refractor and plasmonic crystal, and discuss limitations of the developed technique an...
