Genetic analysis of leaf hydraulics in sunflower (Helianthus annuus L.) under drought stress
Improvement in leaf hydraulics is directly related to the improvement of plant tolerance to drought stress. Therefore, a field and pot experiment was carried out to determine the type of genetic variability and selection of parental types on the basis of combining ability for leaf hydraulics. Genotypes showed similar performance in both experiments; higher values were shown by drought tolerant ...
متن کاملGROWTH AND YIELD OF SUNFLOWER (Helianthus annus L.) AS INFLUENCED BY NITROGEN, SULPHUR AND FARMYARD MANURE UNDER TEMPERATE CONDITIONS
A field experiment was conducted at the Research farm, Division of Agronomy, Sher-e-Kashmir University of Agricultural Sciences and Technology, India for two consecutive rainy (kharif) seasons of 2009 and 2010 to find out the impact of nitrogen, sulphur and farmyard manure (FYM) on growth and yield of sunflower (Helianthus annuus L.). Application of 120 kg N ha significantly increased all the y...
متن کاملAn Overview on Role of Phosphorus on Growth, Yield and Quality of Sunflower (helianthus Annus L.)
Sunflower is an important oilseed crop in India earning lot of revenue. Research on nutritional aspects relating to sunflower cultivation is abundant and is documented comprehensively. However, the role of major nutrients on crop physiology and the effect of these nutrients on growth and yield of oilseed crops in general and sunflower in particular are scanty. Particularly, the role of phosphor...
متن کامل[Study on the quantitative and qualitative composition of moulds colonizing sunflower seeds (Helianthus annus L.)].
INTRODUCTION The aim of study was to estimate the qualitative and quantitative composition of moulds colonizing sunflower seeds on RBCA, YpSs, DG18 media at 25, 37, and 45°C. MATERIAL Twenty samples of sunflower seeds (not roasted and not salted) were used for the analysis. The highest number of moulds were xerophilic species isolated on DG18 at 25°C (33), followed by mesophilic species (29) ...
متن کاملEffects of drought stress and defoliation on sunflower (Helianthus annuus) in controlled conditions
Abstract In order to evaluate the effects of drought stress and defoliation on sunflower, a study was conducted under controlled conditions. Treatments were a combination of three levels of drought ((100, 60 and 30 percent of Field Capacity (FC)) and three levels of defoliation (control, removal of either 4 or 6 leaves from lower part of the plant) laid out, in a Completely Randomized Design w...
