Plants of Ramonda serbica were dehydrated to 3.6% relative water content (RWC) by withholding water for 3 weeks, afterwards the plants were rehydrated for 1 week to 93.8% RWC. Plasma membranes were isolated from leaves using a two-phase aqueous polymer partition system. Compared with well-hydrated (control) leaves, dehydrated leaves suffered a reduction of about 75% in their plasma membrane lip...
in order to locate the qtls involved in the inheritance of agronomical, physiological and metabolitical indicators of drought tolerance in barley, an experiment was carried out using a wheat-barley disomic addition lines. this research was conducted in 2003-2004 at the dry land agricultural research institute, sararood, kermanshah, iran. the results of analysis of variance revealed highly signi...
Employment of Immature Embryo Culture for in Vitro Selection of Drought Tolerant Somaclones of Wheat
MAHMOOD, I., A. RAZZAQ, M. RASHEED, A. QAYYUM and M. AHMAD, 2014. Employment of immature embryo culture for in vitro selection of drought tolerant somaclones of wheat. Bulg. J. Agric. Sci., 20: 155-161 Drought, a serious threat to world agriculture, demands neo-breeding approaches. Tissue culture being a mutagenic process induces somaclonal variations, which can be manipulated for improving dro...
Soybean is an important industrial crop in Croatia and in the last ten years (2000-2009) mean soybean harvested area was 45888 ha (from 35789 to 62810 ha) with average seed yield 2.0 t ha-1 (Central Croatian Bureau of Statistic, 2010). Seed yields of soybean varied in close connection with amount and distribution of precipitation during the vegetation period (Vučić and Bošnjak, 1980; Bošnjak, 2...
Use of physiological parameters as fast tools to screen for drought tolerance in sugarcane: Drought is one of the major limitations to plant productivity worldwide. Identifying suitable screening tools and quantifiable traits would facilitate the crop improvement process for drought tolerance. In the present study, we evaluated the ability of four relatively physiological parameters (variable-t...
in order to study dry matter accumulation in different developmental stages and photoassimilates remobilization in bread wheat genotypes, a field experiment was carried out using a split split plot design based on a randomized complete block design with three replications in torogh agricultural and natural resources research station (mashhad, iran) in 2006-2007 and 2007-2008. main plots were as...
An outdoor pot experiment was carried out in sand culture to investigate the response of spinach (Spinacia oleracea ) cv. “Matador” grown at high salinity to supplementary phosphorus and potassium. Plants were tested during a period from germination to vegetative growth stage. Treatments initiated for seedling and more matured vegetative growth stages were (1) complete nutrient solution alone (...
Salinity is the most important environmental stress that reduces plants growth and yield. It has been shown that salicylic acid, as an endogenous signal, is responsible for inducing stress tolerance in plants. In this experiment, the effect of salicylic acid and sodium chloride on growth of bean (Phaseolus vulgaris) was studied. When bean plants were at two-leaf stage, they were sprayed by thre...
in this study, physiological and morphological responses of five almond cultivars to drought stress were investigated under in vitro conditions. plantlets from five commercial almond cultivars (supernova’, ‘tuono’, ‘sahand’, ‘ferragnes ’ and ‘shahroud 21’] were established in ms medium containing 0.5 mg per liter bap and then subcultured in ms proliferation medium containing 1 mg per liter bap...
to evaluate the effect of ascorbate and gibberellin on some morphological traits and relative water content of medicinal plant fenugreek in different levels of salinity, an experiment was carried out in shahr- e - rey branch of islamic azad university in october 2012. the experiment was arranged as factorial experiment in the basis of completely randomized design with four replications. the exp...
