Different biological and environmental factors, harvesting way, transport, storage time and the method of storage are affected agricultural product properties. As a result of climacteric nature and continuous physiological life of apple fruit, the biochemical changes are very economic. This study was designed for obtain deep knowledge from this changes and effects of them in apple quality. In f...
drought stress is one of the major causes of reduction in crop production. study physiological and biochemical processes related to drought stress can give better insight about mechanism of drought tolerance. to study the physiological and biochemical processes, three genotypes including k-s-31167, ge-288 and naz were subjected to 3 level of drought stress based on 25, 50 and 100 percent of fie...
common vetch ( vicia sativa l.) an annual forage, belonging to the fabaceae family is one of the highly cultivated forage legumes in iran. drought stress is a serious adverse factor that limits plant growth and productivity, inducing a range of physiological as well as biochemical responses in plants. it may also lead to generation of oxygen activated species which in turn result in cell destru...
introduction preterm infants are exposed to irregular light for several weeks or months in the neonatal intensive-care unit (nicu). this lack of maternal entrainment, the exposure to irregular extrauterine lighting and care in the nursery may contribute to the disturbances in body temperature, sleep and physiological changes that are commonly experienced by preterm infants. materials and method...
Coumarins are regarded as a class of plant secondary metabolites of phenyl propanoid group distributed in Apiaceae family. The simple coumarin is the first compound of the class. In the present work, allelopathic potential of coumarin on Lactuca sativa cv.siahoo from physiological and biochemical aspects, was investigated. At first stage, the effects of different concentration of the compound o...
Abstract Background In this research, the effects of exogenous application certain biostimulants [amino acid (AA), humic (HA), fulvic (FA), and seaweed extract (SE)] on fruit yield quality, leaf mineral contents, some critical physio-chemical characteristics grapevine ( Vitis vinifera L.) cv. ‘Yaghouti’ were investigated under well-watered (WW) drought-stressed (DS) conditions. Results Drought ...
