Heat Tolerance in Tomato
High temperature is the prevalent characteristic of subtropical and tropical regions and higher temperature has become an important limiting element for tomato production and yield. Although, tomato crops exhibit anatomical, morphological, physiological, phonological, and molecular responses to tackle with heat stress, but their reproductive stage and yields are extremely influenced by the high...
متن کاملHeat Shock Proteins in Association with Heat Tolerance in Grasses
The grass family Poaceae includes annual species cultivated as major grain crops and perennial species cultivated as forage or turf grasses. Heat stress is a primary factor limiting growth and productivity of cool-season grass species and is becoming a more significant problem in the context of global warming. Plants have developed various mechanisms in heat-stress adaptation, including changes...
متن کاملUpdate on Improving Heat Tolerance in Wheat Physiological Traits for Improving Heat Tolerance in Wheat1[W]
Wheat (Triticum aestivum) represents about 30% of the world’s cereal area, with over 220 million ha cultivated worldwide, often under abiotic stress. Wheat growth can be impaired by heat stress (HS) at any developmental stage, and modeling scenarios predict even warmer temperatures in the future (Easterling and Apps, 2005). The worst impacts of rising temperatures will occur at low latitudes (w...
متن کاملUnifying indices of heat tolerance in ectotherms
1. Researchers commonly rely on indices of heat tolerance to infer the limits of performance in nature. Unfortunately, many methods are used to estimate heat tolerance, creating difficulties when synthesizing or comparing results among studies. Here, we relate several measures of heat tolerance based on the concept of a performance curve. 2. To evaluate our ideas about the link between two meas...
متن کاملHeat tolerance in plants: An overview
Heat stress due to increased temperature is an agricultural problem in many areas in the world. Transitory or constantly high temperatures ause an array of morpho-anatomical, physiological and biochemical changes in plants, which affect plant growth and development and may ead to a drastic reduction in economic yield. The adverse effects of heat stress can be mitigated by developing crop plants...
