Abstract

. Triatminingsih. R. 2009. The Effects of Root Cutting and Seedling Age on the Growth and SexType of Papaya. Out crossing the plant produces population segregation with variation of sex types in differentproportion. In plant crossing, identity of variety is the main key. On the other hand, sex identification technique atearly seedling stage is needed in order to accelerate generation cycle and to increase efficiency on crossing assessment.The objective of this research was to determine the influence of root cutting and seedling age on the growth and sextype of papaya. The research was conducted in Probolinggo, East Java, from April to December 2001. The split plotdesign with 4 replications was used in this experiment, where combination of variety and seedling age as the mainplot, and root cutting as the subplot. The results of this experiment showed that root cutting did not significantly affectthe percentage of survival and the flowering plant. Seedling age significantly affected the percentage of floweringplant, but not on the percentage of survival. Root cutting at seedling stage could affect the percentage of femaleflower and hermaphrodite flower. Root cutting on papaya seedling Sarirona variety at 3 weeks after transplantingin the polybag could decrease the percentage of female flower. While Dampit variety transplanted after 3-week inthe polybag without root cutting gave higher percentage of hermaphrodite flower. The percentage of hermaphroditeflower on Dampit variety was significantly different from Sarirona variety.
