Previous studies with 95 bread wheat doubled haploid lines (DHLs) from the cross Chinese Spring (CS)xSQ1 trialled over 24 yearxtreatmentxlocations identified major yield quantitative trait loci (QTLs) in homoeologous locations on 7AL and 7BL, expressed mainly under stressed and non-stressed conditions, respectively. SQ1 and CS contributed alleles increasing yield on 7AL and 7BL, respectively. T...

pot marigold (calendula officinalis l.) is a medicinal and ornamental plant. the effect of different concentrations of chlormequat (cycocel), and daminozide, two plant growth retardant, on plant height, flowering, the content of essence and some other traits in pot marigold (calendula officinalis) was assessed. plant growth retardants are commonly applied to limit stem elongation and produce a ...

Prunella vulgaris L. is an important medicinal plant with a variety of pharmacological activities, but limited information is available about its response to potassium chloride (KCl) supplementation. P. vulgaris seedlings were cultured in media with four different KCl levels (0, 1.00, 6.00 and 40.00 mM). Characteristics relating to the growth, foliar potassium, water and chlorophyll content, ph...

This research investigated the effects of exogenous sodium nitroprusside (SNP) supplementation as nitric oxide (NO) on alleviating Pb-induced oxidative damage in lemon balm (Melissa officinalis L.) plants. Pb (100, 300 and 500 μM) alone and in combination with SNP (100 and 200 μM) were given to hydroponically grown Melissa officinalis L. plants. The findings suggested that in Pbtreated plants, ...

The low fertilizer utilization at growing season and environment pollution coursed by unreasonable fertilization are becoming global outstanding problems in agricultural production. Scientific and reasonable fertilization based on rapid and nondestructive plant nutrient detection will be a valuable solution for solving above problems. In this study, spectral transmittance in wavelength ranged f...

Genetic maps containing molecular markers are useful tools for the identification of genes underlying quantitative traits (QTLs). Three traits important for plant physiology, i.e. chlorophyll content, sensitivity to GA and sensitivity to ABA, were evaluated for 99 F2 families of the DS2 x RXL10 rye mapping population. The observed variation in the chlorophyll content in rye leaves was shown to ...

the aim of this study was to evaluate genotype×environment interaction (gei) of chlorophyll meter readings (spad) of ten durum wheat cultivars, using data obtained from multi-environment trials during two years, at eight locations. stability and genotypic superiority for spad reading was identified using anova and gge biplot analysis. furthermore, the interrelationships among spad reading and o...

The objective of this study was to investigate the effect of exogenous application of salicylic acid concentrations on the physiological and biochemical traits and essential oil content of chamomile under normal and heat stress conditions as induced by delayed sowing. The experiments were conducted during 2011–2012 as a factorial using a randomized complete block design with three replications,...
