چکیده
S. MANEVA, S., T. VATCHEV and E. MITEVA, 2013. Effect of lead excess in soil on the accumulation of P, K and Na in infected by Fusarium oxysporum f. sp. radicis-lycopersici in tomato (Lycopersicon esculentum Mill.) plants. Bulg. J. Agric. Sci., 19: 972-980 Pot experiments were conducted in greenhouse of IPAZR, “N. Poushkarov”, Sofia, to study the effects of excess lead (Pb) in soils on the uptake of P, K and Na in tomato plants (Lycopersicon esculentum Mill.), cv. Ideal, grown in Fusarium. oxysporum f. sp. radicis-lycopersici (FORl) infected soils. Lead at the rate of 0, 80 and 160 mg kg -1 soil were added in soil in solution form as lead nitrate [Pb(NO

Roles of ascorbic acid on physiological, biochemical and molecular system of Lycopersicon esculentum Mill. against salt stress
Tomato is one of the important plants in the world as a food, medicine etc. it is sensitive to abiotic stresses and its crop is affected by them. Moreover, Ascorbic acid (AsA) is one of the universal of plant defence mechanism against the stresses specially salinity and drought to scavenger’s reactive oxygen species. According to global warming and scarcity of water resources, subsequently dryi...
متن کاملEffect of Calcium Chloride on Growth and Yield of Tomato under Sodium Chloride Stress
The effects of salinity and supplied calcium chloride on growth and leaf ions concentration of tomato (Lycopersicon esculentum L.) were investigated in Gorgan, Iran. A factorial experiment was conducted based on RCBD with four NaCl levels (0, 50, 100, and 150 mM) and four CaCl2 levels (0, 100, 200 and 300 mg L-1). Data of growth, yield and leaf’s Ca, K, and Na content were subjected to analyze ...

Greywater is considered as a valuable resource with a high reuse potential for irrigation of household lawns and gardens. However, there are possibilities of surfactant and sodium accumulation in soil from reuse of greywater which may affect agricultural productivity and environmental sustainability adversely. We conducted a glasshouse experiment to examine variation in growth, water and nutrie...

In order to study the diverse effects of seed priming with 24-epibrassinolide (EBL) (0, 0.1, 1 mg/l) to increase tolerance of tomato plants (Lycopersicon esculentum Mill.) to salinity (0, 70 and 140 mM NaCl), the experiments were conducted as factorial based on completely randomized design at greenhouse condition. Results showed that salt stress significantly decreased the growth of tomato plan...
