Osmotic and oxidative stress responses to iso-osmotic (-0.4 Mpa) NaCl, PEG-6000 and mannitol stress were studied in 15-day old plants of three potato cultivars viz. ‘Kufri Kufri Bahar’ ‘Jyoti’ and ‘Chandramukhi’. After 2-weeks of treatment, plants were analyzed for biochemical and physiological determinants of stress. Relative water content (RWC) and membrane damage rate (MDR) were significantl...

The possible role of photorespiration as a general stress protection mechanism, and in C(4) plant metabolism, is controversial. In particular, the potential involvement of photorespiration in the acquisition of desiccation tolerance in 'resurrection' plants is unknown. An investigation was carried out into whether photorespiration is present in leaves of the C(4) resurrection plant Sporobolus s...

The effects of potassium fertilizer (K2SO4) levels K0, (0), K1,(150) and K2,(250 kg/ha) in two species of Brassica napus (Hyola 401 Hybrid) and Brassica juncea (landrace cultivar), under three irrigation regimes, control (irrigation after 50%,), moderate stress, (irrigation after 70%), and severe stress (irrigation after 90% soil water depletion) were studied in a factorial experiment laid out ...

in order to evaluate the effect of salinity on water relation, ion accumulation, solute sugar, proline content, chlorophyll florescence and seed yield of isabgul (plantago ovata), french psyllium (p. psyllium) and great plantain (p. major), an experiment was conducted at vali-e-asr university of rafsanjan in 2010. this study was carried out as factorial experiment based on randomized complete b...

A pot experiment was conducted to determine the response of two recent forage sorghum cultivars (JS-2002 and Chakwal Sorghum) and an old one (JS-263) to three levels of soil moisture (30%, 50% and 70% field capacity). Several traits were assessed addressing plant morphology, functional growth, leaf water status, biomass yield and water use efficiency (WUE). Soil moisture variation greatly affec...

some of the morpho-physiological characteristics related to the leaf growth and development of phaseolus vulgaris l. genotypes have been studied in the field conditions at the seed and plant improvement institute (spii). the study was performed as split plot experiment in a randomized complete block design with four replications in well-watered and water deficit conditions with eight genotypes ...

Problem statement: Approximately 20% of sugarcane (Saccharum spp.) is grown on sand soils in south Florida, USA. Sugarcane yields in the region linearly increased in last 33 years on organic (muck) soils, but not on sand soils. Water deficit during the formative growth phase on sand soils probably limits sugarcane yields. Approach: A greenhouse study was conducted in 2009 and 2010 to evaluate t...

Abstract Background As a biennial plant, Secale cereale L is usually harvested in the autumn northern part of China where temperature difference between day and night great disparity Through pot experiment, seedlings were cut to 2, 6 10 cm stubble height, simulated freeze-thaw (FT) stress (10/− 5 °C) was carried out after days regrowth. The physiological effects FT with different height reveale...

Water stress is one of the main factors of severe damage and limitation of plant production in Iran. The paper reports a pot experiment conducted by using a factorial experiment based on a completely randomized design with three replications (each replication composed of four pots) to compare the physiological and biochemical characteristics of two varieties of tuberose (double- and single-flow...
