EFFECT OF TEMPERATURE ON PHOTOSYNTHESIS, YIELD ATTRIBUTES AND YIELD OF TOMATO GENOTYPES (Pages : 8 - 11)

The experiment was conducted at the Bangladesh Institute of Nuclear Agriculture, Mymensingh during the period from November 2009 to March 2010 to assess the effects of temperature (32oC) on photosynthesis, yield attributes and yield of five tomato genotypes viz., Binatomato-6, Binatomato-5, CLN-2413, D6 12 and D6 18. Three temperature treatments viz., Ambient, 32oC at pre-flowering stage and 32oC at flowering stage were imposed and continued for 7 days in controlled plant growth chamber. Photosynthetic rate, number of fruits, individual fruit weight and fruit yield/plant significantly decreased with the temperature (32oC) at pre-flowering and flowering stages. Effects of temperature were more pronounced at flowering stage compared to pre-flowering stage. The tomato genotype CLN-2413 showed the best yield performance under the temperature stress.Download
