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 ...

Safflower (Carthamustinctorius L.) is an oilseed crop adapted to drought prone arid and semi-arid environments. This study was conducted to evaluate the effects of water deficit stress on antioxidant activity, membrane stability index (MSI), leaf chlorophyll content, leaf area index (LAI) and their relationship with seed yield using 64 safflower genotypes grown under normal and water defici...

in order to study the effect of ca, k, and mn foliar spray on vegetative traits of safflower (padideh cultivar) under salt stress, a factorial experiment was conducted based on randomized complete blocks design with three replications in vali-asr university greenhouse. factors included salinity with four levels representing 0, 500, 1000, and 1500 mg nacl kg -1, and foliar spray with four level ...

In this study, the response of selected almond cultivars on different rootstocks under drought stress base on Morpho-physiological traits using a factorial experiment in a randomized complete block design with three replications was investigated. The experimental was carried out at the Temperate Fruit Research Center of Horticultural Sciences Research Institute (HSRI) in 2016. The factors inclu...

The research focused on the effects of previous cropping and fertilizers on the LAI, rhythm of the dry matter, leaf disease intensity and amount of yield. Long term field experiments’ results proved that the previous crop fundamentally determines size, rate and dynamics of the dry matter formation in the spring time vegetation period. The LAI index and crop results of winter wheat can be influe...

Our sowing date experiment took place in the Demonstration Garden of Institution of Plant Sciences, Centre for Agricultural Sciences of University of Debrecen, in 2012-2014. The paper contains data of test year 2014. Our purpose, besides several other examinations, was to observe how sowing date influences the leaf area index and the activity of photosynthesis of maize hybrids, and how those fa...
