High relative air humidity influences mineral accumulation and growth in iron deficient soybean plants
Iron (Fe) deficiency chlorosis (IDC) in soybean results in severe yield losses. Cultivar selection is the most commonly used strategy to avoid IDC but there is a clear interaction between genotype and the environment; therefore, the search for quick and reliable tools to control this nutrient deficiency is essential. Several studies showed that relative humidity (RH) may influence the long dist...
متن کاملEthylene synthesis and sensitivity in crop plants.
Closed and semi-closed plant growth chambers have long been used in studies of plant and crop physiology. These studies include the measurement of photosynthesis and transpiration via photosynthetic gas exchange. Unfortunately, other gaseous products of plant metabolism can accumulate in these chambers and cause artifacts in the measurements. The most important of these gaseous byproducts is th...
متن کاملEthylene receptors and molecular mechanism of ethylene sensitivity in plants
A short post-harvest longevity remains a major limiting factor for many crops. Separation from plant leads quickly to ripening of fruits and senescence of flowers. In many species, ripening and senescence are ethyleneregulated. Thus, attempts have been made to retard the post-harvest processes by applying chemicals that inhibit ethylene synthesis. The long-term solution will probably be based o...
متن کاملEffects of Root Anaerobiosis on Ethylene Production , Epinasty , and Growth of Tomato Plants 1
Experiments were performed to determine the source(s) of ethylenecausing epinasty in flooded tomato plats (Lyc_perskoa escultm MilL). Simultaneous measurements were made of ethylene synthesized by the roots and shoots of tomato plants exposed to either aerobic or anaerobk atmospheres in the root zone. When the root zone was made anaerobic by a flowing stream of N2 gas, petiole epiaty ad acceler...
متن کاملEffects of root anaerobiosis on ethylene production, epinasty, and growth of tomato plants.
Experiments were performed to determine the source(s) of ethylene-causing epinasty in flooded tomato plants (Lycopersicon esculentum Mill.). Simultaneous measurements were made of ethylene synthesized by the roots and shoots of tomato plants exposed to either aerobic or anaerobic atmospheres in the root zone. When the root zone was made anaerobic by a flowing stream of N(2) gas, petiole epinast...
