Effects of Two Biochar Types on Mitigating Drought and Salt Stress in Tomato Seedlings

چکیده

Biochar’s underlying biochemical and physiological mechanisms in reducing irrigation salinity stress are elusive. This paper investigates the effects of two types biochar (wood poultry biochar) on growth physiology tomato seedlings exposed to combined drought stress. Two biochar, wood (WB) (PB), were added soil separately, with three gradients 0, 100, 200 mmol/L water supply conditions full (FI) deficit (DI). Results showed that addition effectively improved root potential osmotic plant under Biochar application also mitigated leaf relative content by 9.86% 24.37% stress, respectively. Furthermore, decreased abscisic acid concentrations xylem sap altered structure increased field holding capacity, indirectly increasing supply. While use efficiency did not increase significantly after application, a synergistic seedling consumption occurred. In conclusion, shows promise for promoting help mitigate adverse impacts physiology.

Effects of seed pretreatment with 24-brassinolide on physiological and biochemical characters in tomato plants under salt stress

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...

Effects of salt stress on some growth parameters and chemical contents of two forage sorghum lines

Abstract Soil salinity has been recognized as the most serious problems for agriculture in arid and semi-arid areas of the world. To evaluate the changes in some  growth parameters  and chemical composition of two forage sorghum (Sorghum bicolor var. sudanense  lines (KFS1, KFS2) under salinity stress [0 (control), 3, 6, 9, 12 dS/m of sodium chloride], a pot experiment was carried out at Colleg...
