Accumulation of Proline under Salinity and Heavy metal stress in Cauliflower seedlings
Salinity and heavy metals affect the growth and development of higher plants and also their productivity. In the present study, Cauliflower (Brassica oleracea var botrytis) seeds were allowed to germinate and grow in the absence (control) and presence of different concentrations (50, 100, 250, 500, 750 and 1000 μM) of NaCl, CdCl2, HgCl2 and ZnCl2. Seed germination and growth parameters of seedl...
متن کاملProline accumulation and metabolism-related genes expression profiles in Kosteletzkya virginica seedlings under salt stress
Proline accumulation is a common response to salt stress in many plants. Salt stress also increased proline concentration in roots, stems, and leaves of Kosteletzkya virginica seedling treated with 300 mM NaCl for 24 h and reached 3.75-, 4.76-, and 6.83-fold higher than controls. Further study on proline content in leaves under salt stress showed that proline content increased with increasing N...
متن کاملProline accumulation in lemongrass (Cymbopogon flexuosus Stapf.) due to heavy metal stress.
Toxic heavy metals viz. lead, mercury and cadmium induced differential accumulation of proline in lemongrass (Cymbopogon flexuosus Stapf.) grown in soil amended with 50, 100, 200, 350 and 500 mg kg(-1) of the metals have been studied. Proline accumulation was found to be metal specific, organ specific and linear dose dependant. Further, proline accumulation following short term exposure (two mo...
متن کاملEffects of Salinity and Laser Radiation on Proline Accumulation in Seeds of Spring Wheat
Laser is one of the sources that induce a biological effect in higher plants. The positive effect of laser on some crops has been proved. This research was carried out to study the effect of laser radiation on the accumulation of proline in spring wheat (Triticum aestivum cv. Kavir) under different NaCl treatment levels. Semi-coherent red beam, infrared beam and one-second harmonics of Neodymiu...
متن کاملResponses of endogenous proline in rice seedlings under chromium exposure
Hydroponic experiments were performed to exam the dynamic change of endogenous proline in rice seedlings exposed to potassium chromate chromium (VI) or chromium nitrate chromium (III). Although accumulation of both chromium species in rice seedlings was obvious, more chromium was detected in plant tissues of rice seedlings exposed to chromium (III) than those in chromium (VI), majority being in...
