Effects of melatonin on seedling growth, mineral nutrition, and nitrogen metabolism in cucumber under nitrate stress.
In China, excessive use of nitrogen fertilizers in glasshouses leads to nitrate accumulations in soil and plants, which then limits productivity. Melatonin, an evolutionarily highly conserved molecule, has a wide range of functions in plants. We analyzed the effects of melatonin pretreatment on the growth, mineral nutrition, and nitrogen metabolism in cucumber (Cucumis sativus L. "Jin You No. 1...
متن کاملEffect of Cadmium Levels on Seed Germination and Seedling Growth of Spinach (Spinacia oleracea) Under Salinity Stress
Cadmium is highly toxic heavy metal. Soil factors such as pH, caution exchange capacity, CaCO3 content and salinity have a significant influence on Cd uptake by plants. Moreover, soil salinity has a great impact on crop yield in Iran. Therefore, the effect of four salt levels (0, 45, 90, 180 mM) of NaCl solutions and four concentrations (0, 15, 30, 60 ppm) of Cadmium sulfate solutions on seed g...
متن کاملSeedling Growth of Two Honey Mesquite Varieties Under CO2 Enrichment
Seedlings of 2 varieties of honey mesquite (Prosopis glandulosa var. glandulosa and P. glandulosa var. torreyana) were exposed to 2 concentrations of atmospheric carbon dioxide (CO2) (368 and 704 lmol mol ) in environmentally controlled glasshouses under near-optimal temperature and soil water conditions to determine if CO2 enrichment alters aboveand belowground growth responses. CO2 enrichment...
متن کاملEffect of Cadmium on Seed Germination and Seedling Growth of Four Wheat (triticum Aestivum L.) Cultivars
Cadmium (Cd) is extremely toxic metal and reduces plant growth. Therefore, study was conducted to evaluate the effect of various Cd levels 0, 5, 20, 50 and 80 mg L on seed germination and seedling growth of four wheat cultivars (Sehar-06, Fareed-06, Inqlab-91, Chakwal-50). Cadmium showed toxicity at 5 mg L in case of root and shoot growth whereas 20 mg L in case of seed germination and germinat...
متن کاملImpacts of Cadmium and Manganese on in Vitro Seed Germination and Seedling Growth of Horsegram
Heavy metal stress is one of the key factors for crop yield along with other abiotic stresses such as drought, salinity, extreme temperature and light. Due to natural and anthropogenic activities heavy metal pollution is increasing daily. Hence, it is must to know the effects of heavy metals in depth on crop growth and development ultimately yield levels. In the present work we assessed the imp...
