Abstract
The effects of KNO3 concentration and aeration during seed priming on seed germination and vigor of papaya cv. Khaek Dam Kaset were studied in order to improve seed germination and speed of germination. The experiment was conducted at Seed Technology Laboratory, Department of Horticulture, Faculty of Agriculture, Kasetsart University, Bangkok during November 2019 to January 2020. The experiment was designed in 3×2 factorial in completely randomized design (CRD) with non-primed seeds (control). There were two factors. Factor A was concentration of KNO3: 0% (reverse osmosis water), 3% and 5%. Factor B was aeration: non-aeration and aeration for 24 hours. Seeds were then dried until nearly initial seed moisture content was about 8%. The results showed that seed priming with KNO3 solution at 0%, 3% or 5% without aeration or with aeration for 24 hours, except non-primed seed (control), had no effect on germination but it had faster days to emergence (DTE) and mean germination time (MGT) than non-primed seeds. Moreover, non-aeration and aeration during seed priming had no effect on germination, DTE and MGT. Thus, seed priming with 3% KNO3 solution for 24 hours without aeration could increase the speed of germination about 3 days when compared with non-primed seeds.
