ABSTRACT
Jackfruit yield is affected due to sudden cold snap during flowering phase. The response of pollen viability to low temperature regimes was studies to determine the suitable condition hence, the study was carried out on pollen viability studies in different accessions of jackfruit at the PGRI laboratory ICAR-Indian Institute of Horticultural Research (IIHR), Hessaraghatta Lake Post, Bangalore-89.During 2014-15 and 2015-16, the pollen viability were recorded with four different chemicals viz., A); Control (distilled water), B);10% sucrose solution, C); 10% sucrose solution+20ppm boric acid and D); 10% sucrose solution+200 ppm Ca(No3)2+200 ppm MgSo4+100 ppm K(No3)2+100 ppm boric acidwere tried at 28.5 °C (ambient temperature). Among the four different chemical treatment the maximum pollen viability were recorded the treatment D) 32.24 per cent followed by the chemical treatment C)29.70 per cent, B) 27.12 per cent and the minimum pollen viability were recorded in the treatment A) 22.72 per cent. During 2014-15 and 2015-16, the pollen viability also studied with different timing hour’s intervals viz., 2hr, 4hr, 6hr and 8hr among the different time interval 6hr with respect to different chemicals followed by 4hr, 8hr time intervals and minimum pollen viability were found 2hr timing. Among the accessions the accessions A-7, A-6 and A-5 were recorded maximum pollen viability whereas the minimum pollen viability were recorded in the accession A-4 with respect to different chemicals treatments and different timing intervals during both the year of study.
