The trial with 11 genotypes of winter oilseed rape (Brassica napus subsp. napus) with different provenance was based on experimental station Borovce near SCAR – RICP Piešťany (Slovak Republic) in autumn 2008 (the Trnavská pahorkatina locality, altitude 167 m, maize growing region). Approximately in weekly intervals, since beginning of April to middle of June 2009, for the purpose of growth anal...

the phenotypic diversity of potato, solanum tuberosum was assessed using morphological traits. to verify, how this diversity is distributed among the main potato varieties in the growing areas in iran. a total of eleven potato varieties, ramose, sante, shepody, marfona, maradona, milova, santana, boren, cosima, granola and agria, were evaluated under vivo and situ experimental conditions in isf...

in order to study of the effect of priming and salinity on physiological and chemical characteristics of wheat(triticum aestivum l.), an experiment was carried out at the experimental farm of shiraz university. results showedthat primed plants significantly reduced its gas exchanges by accelerating senescence under a series of salt stress,which became more serious along with the increasing of s...

Crop models need accurate simulation of the interdependent processes of crop development and leaf area production. Crop development proceeds according to genotype characteristics and environmental influences, specifically temperature and photoperiod. It can be partly described by thermal requirements for development intervals and coefficients that describe genotype adaptation. The objectives of...

The present study was carried out in a field located at Department of Botany, University of Karachi where soil was treated with various concentrations of pesticides before sowing. Combined effects of pesticides on soybean growth and nutritive composition of seeds were observed. Pesticide treated soil had significant effects on leaf growth components such as leaf area ratio, leaf area index, spe...

Common features in the time-course of expansion of leaves which considerably differed in final area, due to phytomer position, growing conditions and genotype, were identified. Leaf development consisted of two phases of exponential growth, followed by a third phase of continuous decrease of the relative expansion rate. The rate and the duration of the first exponential phase were common to all...
