    Abstract Application of biochar to agricultural soils is mostly used to improve soil fertility. Experimental treatments were comprised of two factors: i) drought at two level, i.e., 80% and 40% water holding capacity (WHC) which was maintained on gravimetric basis ii) three levels of biochar i.e., control, 2 t ha-1 and 4 t ha-1 added to soil. Experimentation was done to examine potential of biochar application to enhance the growth attributes, water relations, photosynthetic pigments and antioxidants activities in maize (Zea mays L.) seedlings. Results of study revealed that biochar application increased the growth qualities (total seedlings biomass, dry weight of… More >

    Genetic analysis for quantitative traits in bread wheat exposed to irrigated and drought stress conditions

    Ataei R1, M Gholamhoseini1, M Kamalizadeh2

    Phyton-International Journal of Experimental Botany, Vol.86, pp. 228-235, 2017, DOI:10.32604/phyton.2017.86.228

    Abstract Understanding the genetic control of traits associated with yield helps breeders to utilize their germplasm in a more efficient and consistent manner and to make good choices in breeding programs. The current study was carried out to study the genetic control of some quantitative traits in bread wheat (Triticum aestivum L.) and to examine plant responses under full irrigation and drought stress conditions. For this purpose, six generations derived from a cross between two lines (Bezostaya as tolerant parent and 518 as a susceptible parent) were evaluated for grain yield (GY), plant height (PH), peduncle (PL) and spike (SL) lengths,… More >

    Physiological response of early and late maturity oilseed rape cultivars to drought under two climate conditions

    Jabbari H1, M Gholamhosseini1, M Naeemi2, A Nasiri3

    Phyton-International Journal of Experimental Botany, Vol.87, pp. 133-142, 2018, DOI:10.32604/phyton.2018.87.133

    Abstract Two experiments were performed in 2011-2012 to investigate the response of three oilseed rape cultivars to drought stress, grown under two climate conditions in Iran (cold and hot climates). The experiments were conducted using a randomized complete-block design arranged in split-plot with three replicates. The irrigation treatments (FI: full irrigation; WIF: withholding irrigation at flowering stage, and WIS: withholding irrigation at the silique formation stage until physiological maturity) were allocated to main plots, whereas subplots consisted of the oilseed rape cultivars: early maturating (GKH2005), relatively late maturing (Opera) and late maturing (Okapi). Drought caused a significant reduction in seed number,… More >
