EFFECT OF DIFFERENT TEMPERATURE LEVELS ON GERMINATION, ROOT AND SHOOT DEVELOPMENT OF RICE VARIETIES (Pages : 11 - 12)
M.T. ISLAM AND M. KHATOONTemperature is one of the most important environmental factors influencing rice germination growth, development and yield processes. An experiment was conducted with 12 rice varieties viz. Binasail, Iratom-24, Binadhan-4, Binadhan-5, Binadhan-6, Binadhan-7, Binadhan-8, Binadhan-9, Binadhan-10, Binadhan-11, Binadhan-14 and Binadhan-17 in plant growth chamber at Bangladesh Institute of Nuclear Agriculture during July to December, 2015 to assess the effect of different temperature levels on germination, root and shoot length and to find out suitable temperature for proper germination. Five temperature treatments viz. 20, 25, 30, 35 and 40oC were imposed for 7 days. Rice varieties showed better germination% at 25-35oC, medium at 40oC and the lowest at 20oC. The lowest root and shoot length was also recorded at 20oC. More than 95% germination was observed in Binasail, Iratom-24, Binadhan-6, Binadhan-7, Binadhan-8, Binadhan-10, Binadhan-11 and Binadhan-14 under the temperature treatments. Among those Binasailand Binadhan-7 also showed better root and shoot length. Download
