Abstract

Seed viability is influenced by genetic factors, seed ages, and the physical properties of the seed itself. This research was aimed at determining effects of seed storage life and scarification on seed viability of soursop. The experiment was conducted from March to May 2013 in Sumani Experimental Tropical Fruit Research Institute Solok, West Sumatra. The experiment was arranged in a completely randomized design (CRD) with four replications. The study consisted of two sets of treatments. The first was seed storage, i.e., 6 months storage and without storage and the second one was seed scarification, i.e. without scarification and scarified seeds. The results showed that the soursop seeds that were stored for six months decreased germination rate (GR) from 82.5% to 65.0% and decreased maximum growth potential (MGP) from 86.0% to 70.5% but did not decrease vigor index and seedling height. In addition, seed scarification lowered vigor index and dry weight of normal seedling. Unscarified seeds did not lower GR and this suggests that scarification by cutting the base of the seeds is not effective for soursop seed.

Abstract

The research was conducted at Post Harvest Laboratory of Indonesian Tropical Fruit Research Institute (ITFRI) from March to May 2010. The design used was a randomized complete block design with 4 replicates. Papaya genotypes tested were  BT-01, BT-02, BT-03, and BT-04. The results showed that papaya genotypes of  BT-01, BT-02, BT-03, and BT-04 were not significantly different each other on physical fruit characters i.e. fruit length, fruit width, fruit weight, and stem length.  However, the thinnest fruit flesh was found at BT-3 genotype and the thicknest flesh was at BT-2 genotype. The lowest fruit cavity was found at genotype BT-1 and the highest was at the BT-2.  The lowest hardness of fruit skin and flesh  was found at genotype BT-4 and the highest hardness of skin was at BT-3,  while the highest hardness of flesh was at BT-1 and BT-2.  Chemical quality of total dissolved solid, vitamin C, acid content, and water content was not significantly different among the four genotypes BT-1, BT-2, BT-3, and BT 4.
