The study was carried out to evaluate the effects of soil application of humic acid and calciumon morpho-physiological traits and Na+, Mg2+, Ca2+ uptake of Pistachio seedling (Akbari) grown under salt stress.  A completely randomized design was used with four replications in greenhouse conditions. The experimental treatment consisted of four levels of humic acid (Bis humic) (0, 4, 8 and 12 gr k...

Artificial excision of the distal part of acorns in order to promote germination is well researched in oak seedling cultivation studies. However, studies of combined effects of cotyledon excision and nursery fertilization on container seedlings are lacking, especially for seedling root growth and outplanting performance. This study aimed to explore the main effects of cotyledon excision on Quer...

agrobacterium rhizogenes (pri), a causative agent of hairy root disease, effectively induces hairy root formation in a variety of plant species. in our study four bacterial strains ar15834, a4, 9435 and c318 and three explants types leaf, stems and roots, were examined. hairy roots were induced from roots, stems and leaf explants. the highest transformation efficiency of 77% was achieved by usi...

geostatistical techniques were used to describe the spatial distribution of weeds, under conventional management conditions and theirs effect on wheat biomass production over the course of one growing season (2008-2009), in a wheat (triticum aestivum l.) field at research station of shahrood university, iran. weeds seedling were identified and counted at 121 points of field based on two interva...

This investigation was carried out to determine the effects of gamma radiation on germination and physiological characteristics of wheat seedlings. Two wheat genotypes (Roshan and T-65-58-8) were irradiated with 100, 200, 300 and 400 Gy. The results showed that MGT (Mean Germination Time), root and shoot length, and seedling dry weight decreased with increasing radiation doses but final germina...

An experiment was conducted in pots at the demonstration farm of College Agriculture, University Bahri, Sudan during 2016 - 2017 seasons to study effect different NaCl concentration soil on seed germination and seedling growth sugar beet. The arranged randomized complete block design (RCBD) with three replications four treatments sodium chloride concentrations soil; they were 4 dS/m, 8 12 16 dS...

Parameters that show a significant genotypic variation at early growth stages and are associated with salt tolerance at later stages may be used as rapid and economic screening criteria in breeding programs. The objective of this study was to test growth parameters at early growth stages for evaluating the salt tolerance of wheat genotypes. Ten wheat genotypes that differ from their salt tolera...
