Relationships Between Seedling Growth Rate and Yield of Maize Cultivars Under Normal and Water Stress Conditions
Abstract Effects of water stress on root and leaf growth rates and their relationships with yield under normal and water stress conditions were examined at the Greenhouse and Research Field of Faculty of Agriculture, Kerman University, Iran, using seven maize cultivars including SC-404, SC-704, BC-666, TC-647, DC-370, Jeta and Kordona. During a period of 14 days, water stress at -0.4 MPa was ...
متن کاملMaize response to water, salinity and nitrogen levels: physiological growth parameters and gas exchange
A split-split-plot design with three replications in two years of 2009 and 2010 was conducted to investigate the effect of different levels of irrigation water (main plot), salinity of irrigation water (sub-plot) and nitrogen fertilizer rate (sub-subplot) on maize growth rate and gas exchange. Irrigation treatments were I1 (1.0 crop evapotranspiration (ETc)+0.25ETc as leaching), I2 (0.75I1)...
متن کاملGrowth response of major USA cowpea cultivars II. Effect of salinity on leaf gas exchange
In an effort to elucidate the physiological processes involved in cowpea differential growth response of four major USA cowpea cultivars (CB5, CB27, 8517 and 7964) to increasing salinity, we investigated the effect of salinity on leaf gas exchange of net photosynthetic rate per unit leaf mass (Pnm) and per unit leaf area (Pna), and stomatal conductance (gs) of the four cowpea cultivars. The exp...
متن کاملPhysiological Performance of Soybean Cultivars Under Salinity Stress
Abstract Two experiments with factorial arrangements on the basis of randomized complete block design in three replications were conducted in 2007 and 2008, to evaluate chlorophyll content index (CCI), fluorescence of chlorophyll, proline content and grain yield of three soybean cultivars (Williams, Zan and L17) under a non-saline (control) and three saline (3, 6 and 9 ds/m NaCl) conditions...
متن کاملModification of the saffron model for growth and yield prediction under different irrigation water salinity, manure application and planting methods
The Saffron Yield Estimation Model (SYEM) was modified for salinity conditions, cowmanure application and planting methods using two-year experiments data in Badjgah region ofIran. A split-split plot arrangement was conducted in complete randomized block design duringtwo years with irrigation water salinity levels (0.45 (fresh water, S1), 1.0 (S2), 2.0 (S3) and 3.0(S4) dS m-1) as the main plot,...
