بررسی مزرعهای اثر شوری روی صفات فیزیولوژیکی و مرفولوژیکی و عملکرد ارقام و لاینهای منتخب برنج

hoo.comIn order to evaluate morphological characteristics and yield components of selected rice genotypes to salinity stress, a field experiment was carried out in RCBD with three replications in 2013. Seven rice genotypes were studied as treatments including: FL478, SL10, SL11, SL12, SL13, Shirodi, Tarom). In this research we measured some agronomic treats such as: Plant height (PH), panicle length (PL), number of effective tillers (NT), flag leaf SPAD, 1000 grain weight and Yield. Analysis of data showed that the effect of salt stress on PH, leaf SPAD and PL was significant at 1 % level; on NT and 1000 GW at 5 % level. But, no significant effect was found on yield. For PH, Tarom and FL47 had the highest and lowest height, respectively. The line of SL10 and Tarom had the most SPAD and the least one, respectively. The line of SL12 and the line of FL478 had the most panicle length and the least one, respectively. For 1000 grain weight, SL12 and Tarom were the heaviest and lightest .For NT, Shirodi and SL13 had the most and least number of effective tillers, respectively. Based on this experiment, salt affect was no significant on Yield.
