to evaluate the effect of environment on the general and specific combining ability of virginia tobacco genotypes, five varieties were intercrossed in combination in 2007 in a half – diallel design. in 2008, the ten f1 population and the five parental lines were sown in two different conditions (drought stress and non-stress) using a complete randomized block design with three replications and ...
in order to study the effect of light quality and quantity on morphological and physiological characteristics of two late and early maize (zea maize l.) s.c., an experiment was conducted in greenhouse conditions, ferdowsi university of mashhad, iran, during 2008. the experiment was carried out factorial based on randomized complete block design with six treatments and three replications. differ...
In the turfgrass industry, the need for salinity tolerant turfgrasses is increasing because of the increased use of saline and non-potable water. Greenhouse container experiments were conducted to determine the relative salinity tolerance and growth responses of eleven native populations of tall fescue (Festuca arundinacea Schrub) (TF), including: Semirom, Mashhad, Sanandaj, Yasuj, Yazd Abad, D...
to evaluate the genetic diversity, four wild wheat species named t. boeticum, t. thaudar, t. urartu, t. arrarticum were studied. quantitative traits were measured according to ibpgri. analysis of variance showed significant difference for all landraces. result of pearson correlation analysis showed positive and negative significant correlations between some of the traits. in principle component...
Use of Chitosan-PVA Hydrogels with Copper Nanoparticles to Improve the Growth of Grafted Watermelon.
Modern agriculture requires alternative practices that improve crop growth without negatively affecting the environment, as resources such as water and arable land grow scarcer while the human population continues to increase. Grafting is a cultivation technique that allows the plant to be more efficient in its utilization of water and nutrients, while nanoscale material engineering provides th...
Potamogeton nodosus tubers produce floating-type instead of submersed-type leaves when exposed to 10(-5) molar synthetic abscisic acid. Abscisic acid-induced leaves have stomata on upper leaf surfaces and higher width/length ratios than controls. These effects are wholly or partially overcome by simultaneous exposure to abscisic acid combined with gibberellic acid, kinetin, or benzyladenine.
ABSTRACT: Leaf area is an important growth variable in agricultural crops and the leaf main of interest tobacco industry. So, aim this scientific research was to estimate Burley by linear dimensions leaves determine which mathematical model more adequate for purpose. Two experiments were carried out with tobacco, cultivar DBH 2252, 2016/2017 2018/2019 years, respectively, municipalities Itaqui ...
The present investigation was carried out to enhance the plant growth and production of curcuminoids and essential oils from turmeric (Curcuma longa) by gamma rays treatments. The plant samples of turmeric were collected from different regions of Kasur, Bannu and Faisalabad, Pakistan. The rhizomes were irradiated with 00 as control, 10, 20, 30, 40, 50, 60, 70, 80, 90 and 100Gy by cobalt 60 sour...
Genetic diversity of 13 new cereals, primary tritipyrum lines, five triticale lines and nine Iranian bread wheat varieties was studied under the randomized completely blocks design in terms of agronomic and morphological traits. The highley significant difference was observed between genotypes for all traits except in the filamental leaf length, main leaf length and main leaf width. The highest...
Silicon (Si) amendment to plants can confer enhanced resistance to herbivores. In the present study, the physiological and cytological mechanisms underlying the enhanced resistance of plants with Si addition were investigated for one of the most destructive rice pests in Asian countries, the rice leaf folder, Cnaphalocrocis medinalis (Guenée). Activities of defense-related enzymes, superoxide d...
