Profitability Assessment of Abscisic Acid Application on Sunflower (Helianthus annuus L.) Hybrid under Drought and Well Watered Conditions
Profitability assessment has prime importance for every crop husbandry practice and cultural operation. For this purpose, two field experiment was carried out to investigate the response of spring planted sunflower hybrids to different irrigation levels/schedules and foliar application of abscisic acid. Two studies were done at the Agronomic Research Farm, University of Agriculture, Faisalabad,...
متن کاملAbscisic acid content of a nondormant sunflower (Helianthus annuus L.) mutant
A sunflower (Helianthus annuus L.) mutant was observed in the progeny of a cross between the sunflower cultivar HA 89 and an amphiploid of a H. divaricatus L. × P21 cross that exhibited loss of dormancy induction in the developing embryo. Seeds of this mutant frequently germinate on the head about 40 d after pollination (DAP). In contrast to other nondormant sunflower mutants reported previousl...
متن کاملPhenotypic and molecular marker distance as a tool for prediction of heterosis and F1 performance in sunflower (Helianthus annuus L.) under well-watered and water-stressed conditions
The aim of this study was to determine phenotypic and genotypic distances in parental lines of diallel population of sunflower, and to identify correlation between both distances with F1 performance, specific combining ability (SCA) and absolutely mid-parent heterosis. The morphological distance (Euclidean distance; EDs) and genetic distance (Jaccard`s distance; JD) among five sunflower parenta...
متن کاملGenetic 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 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...
