| Abstract: |
Seed germination was most essential stage of a plant life cycle and is strongly influenced by temperature conditions. The purpose of this study is that we have tried to know the stage of seed germination of papaya (Carica papaya L.) under the BOD incubator condition. Temperature three levels (20, 25, 30°C) were used. The objective of this study is to see how germination is accelerated at different temperatures by treating seeds with growth regulators, chemicals, and organic supplements. Since the seed coat contains sarcotesta, which inhibits germination, seed treatment is necessary. For papaya seed soak coconut water @ 50%, tomato juice @ 20%, cow urine @ 10%, GA3 @ 200 ppm, NAA @ 200 ppm, KNO3 @ 0.5% and normal water (control) twenty four hours. Use moist filter paper in petri dishes for this investigation, were 20 seeds placed in each petri plate, after that data observation was taken by placing the petri plate on BOD incubator. In case T2 (92.66%) recorded the highest number of seed germination at temperature range 300C followed by T1 (coconut), T3 followed by while seedling length, root length and shoot length were maximum at T1 (water coconut @ 50%) recorded 6.5, 3.35 and 9.423 and lowest at T6 was found in variety "Ranchi" under incubator control condition.
