QTLs underlying Rice Tolerance to Low-Potassium Stress in Rice Seedlings
for testing genotypic performance relating to a specific nutrient. To select for basic materials to develop a cultiPotassium is an important nutrient in plant growth and developvar with higher tolerance to nutrient deficient stress, ment of rice (Oryza sativa L.), but K availability may be seriously limited in developing countries. Genotypic variation in tolerance to the concept of the “specifi...
متن کاملCharacterization of high temperature induced stress impairments in thylakoids of rice seedlings.
Exposure of isolated thylakoids or intact plants to elevated temperature is known to inhibit photosynthesis at multiple sites. We have investigated the effect of elevated temperature (40 degrees C) for 24 hr in dark on rice seedlings to characterize the extent of damage by in vivo heat stress on photofunctions of photosystem II (PSII). Chl a fluorescence transient analysis in the intact rice le...
متن کاملstudy of some cryoprotectives role to induce low temperature tolerance in rice (oryza sativa l.) seedlings
to study of some cryoprotectives in cold tolerant rice genotypes (irctn33 and irctn34) and cold-sensitive rice genotype (hoveize) were selected in previous experiment, fourteen-day rice seedlings exposed fourteen days in 13/15oc (respectively night-day) temperatures as the stress treatment and 22/28oc (night-day) temperature as control treatment in phytotrone. this experiment was conducted in f...
متن کاملEvaluation of low temperature tolerance indices in seedlings of Citrus aurantium under potassium nitrate nutrition.
In order to evaluate the effects of potassium nitrate nutrition on some low temperature tolerance indices in Citrus aurantium seedlings a factorial experiment was conducted based on a completely randomized design with four replications at the Institute of Citrus Research in Ramsar. Treatments were potassium nitrate nutrition at four levels (0, 2.5, 5, and 10 mM) and temperature at four levels (...
متن کاملPolyamines in Rice Seedlings under Oxygen-Deficit Stress.
Incubation of 3-d-old seedlings of Oryza sativa L. cv Arborio under anaerobic conditions, leads to a large increase in the titer of free putrescine while aerobic incubation causes a slight decrease. After 2 days, the putrescine level is about 2.5 times greater without oxygen than in air. The rice coleoptile also accumulates a large amount of bound putrescine and, to a lesser extent, spermidine ...
