In order to increase the quality of agricultural products and improve healthy food production systems, application of organic fertilizers has become very important in agroecosystems. To investigate the effect of different concentrations and time of humic acid foliar application on the qualitative characteristics and shoot and grain micronutrients content of Triticale, an experiment was conducte...
The basic premise of high yield in rice is to improve leaf photosynthetic efficiency and coordinate the source-sink relationship in rice plants. Quantitative trait loci (QTLs) related to morphological traits and chlorophyll content of rice leaves were detected at the stages of heading to maturity, and a major QTL (qLSCHL4) related to flag leaf shape and chlorophyll content was detected at both ...
Sixty-nine cultivars of rice were examined for fourteen biometrical characteristics to study the degree genetic divergence, heritability and gain as a percentage mean, character relationship path coefficient analysis. Yield per plant reported highest estimate PCV GCV followed by total effective tillers plant, hundred seed weight, number filled seedsper panicle flag leaf length indicating that t...
due to cereal are affected by drought stress in their lifetime. in order to study gene action of bread wheat under drought stress condition, a generation mean analysis was performed using f1, f2 and f3 generations derived from roushan and kavir. generation mean analysis was performed based on joint scaling test. genetic parameters including additive effect (d), dominance effect (h), additive×ad...
Drought is a major abiotic stress, severely affecting the physiological processes and growth of plants. The present investigation aimed to evaluate impacts drought stress with three periods for irrigation: every 3 days(control), 6 days, 12 days foliar spray different concentrations ascorbic acid (0, 75, 150, 225) mg.L-1 on wheat plant. Pots experiment was conducted as completely randomized desi...
Wheat leaf non-sequential senescence at the late grain-filling stage involves the early senescence of younger flag leaves compared to that observed in older second leaves. On the other hand, sequential senescence involves leaf senescence that follows an age-related pattern, in which flag leaves are the latest to undergo senescence. The characteristics of sugar metabolism in two sequential senes...
Sorghum is a grain plant that source of food, biofuel and feed, which can be produced using the techniques ratoon cultivation. The objective this study to assess nutrition content, performance four sorghum genotypes vegetative characteristics ratoon. research was carried out from December 2020 July 2021 at Ciawi Research Garden, Livestock Institute. employed treatments (genotype) three replicat...
The appropriate timing of developmental transitions is critical for adapting many crops to their local climatic conditions. Therefore, understanding the genetic basis of different aspects of phenology could be useful in highlighting mechanisms underpinning adaptation, with implications in breeding for climate change. For bread wheat (Triticum aestivum), the transition from vegetative to reprodu...
in order to study the effects of conventional and conservation tillage with management residue on wheat physiological properties, a field experiment was conducted in 2013-2014 at mashhad agricultural and natural resources research center of razavi khorasan province. this experiment was carried out as split plot design based on a randomized complete block design with three replications. main plo...
We investigated the natural variations in the flag leaf morphology of rice. We conducted a principal component analysis based on nine flag leaf morphology traits using 103 accessions from the National Institute of Agrobiological Sciences Core Collection. The first component explained 39% of total variance, and the variable with highest loading was the width of the flag leaf (WFL). A genome-wide...
