The initial response of plants to aluminum (Al) is the inhibition of root elongation, while the transition zone is the most Al sensitive zone in the root apex, which may sense the presence of Al and regulate the responses of root to Al toxicity. In the present study, the effect of Al treatment (30 μM, 24 h) on root growth, Al accumulation, and properties of cell wall of two pea (Pisum sativum L...
A transient one-dimensional model of the vertical movement of water and salt in the mangrove root zone is investigated. This is an extension of a previous steady state model which assumed that the ability of the mangrove roots to take up water is uniformly distributed throughout the soil and that the root water uptake is reduced if there is nonzero salt concentration around the roots. We show h...
background and objectives: the seed extract of silybum marianum contains seven flavonolignans known collectively as silymarin. these metabolites can be produced in hairy root cultures of s. marianum. the effect of different physical factors can change root biomass and silymarin production which has been investigated in the present study. methods: the effect of different physical factors of temp...
Root-zone temperature (RZT) is an indispensable environmental factor for the proper growth and development of plants. Low RZT one major limitations agricultural production during cold seasons. In this study, physiological responses tomato seedlings to low stress (10 °C) its recovery were investigated with hydroponic cultivation in artificial climate-controlled chamber. The reaction was evaluate...
