MARASIGAN, RENE R., Applied Research IV (Agri-Science Curriculum) Don Severino Agricultural College, Indang, Cavite, Philippines, March, 1988. GERMINATION RESPONSE OF GUYABANO SEEDS TO STORAGE CONDITIONS CHEMICAL TREATMENTS. Adviser; Mr. Alejandro C. Mojica The study was conducted to find out which of the storage conditions and chemical treatments will give guyabano seeds (ordinary and sweet guyabano) a high percentage germination for a short period of time. The different treatments used were sulfuric acid (T 1), hydrochloric acid (12), nitric acid ('23), hot water soaking refrigeration (15), wet cloth (T6), plastic (T) and control (28). Treated guyabano seeds showed a very high percentage germination as compared to control. Treatment 1 (sulfuric acid) had the highest percentage germination for a short period of time in both ordinary and sweet guyabano seeds. On the average number of leaves and on the average height of seedlings, seeds treated with 3% sulfuric acid (T1 ) had the highest number of leaves with the mean of 7 leaves and the tallest seedling height Of 1707 centimeters in ordinary guyabano seedlings and 18.95 centimeters in sweet guyabano seedlings. These proved that seed treatments had a very remarkable effect on the germination and growth of plants. The seeds stored in plastic (T) had given the lowest percentage germination for a longer period and had given slow growth in terms of the number of leaves and seedling height.
