" Screening and Evaluating Wild Cotton for Salt Tolerance Characteristics"
Salinity is a gloval problem. Over time salinity interferes with seed germination, plant developmental growth, fruiting capabilities, fiber yield and maturity. It also causes oxidative damage and deterioration of the leaves by changing the plant's metabolic system. To study this effect, wild cotton cultivars are grown under controlled conditions in a hydroponic medium. Images collected form the scanning electron microscope and the transmission electron microscope showed salt present on the stroma. Spectrometric analysis of glucose depositions on the leaf surface of a surviving genotype showed the presence of alginic compounds.
