Chapter 7 - Propagation of Scaphium lychnophorum Pierre. and Baccaurea sylvestris Lour. for Enriching Community Forests

Abstract

The main objective of the study was to identify the best propagation methods for Baccaurea sylvestris Lour. and Scaphium lychnophorum Pierre. The study propagated B. sylvestris species by seed and S. lychnophorum by grafting. To access the viability and seed quality test for B. sylvestris, cut testing methods along with a germination test were conducted for three preplanting treatments: (1) control, (2) soaking in hot water at 70°C and left until the water becomes normal for 24h, and (3) soaking in normal water for 24h. Propagation of S. lychnophorum was grafted to assess the viability, number of emerged buds, and time of emergence for three methods: (1) chip budding, (2) patch budding, and (3) side grafting. The results showed that the rate of seed viability was 100% after 2 weeks of storage. The germination time was not significant but the rate of germinated seeds was significant for each treatment method. Percentage of germinated seeds by the soaking in hot water (at 70°C) treatment method was the highest. The rate of viability buds was not significant but the emergence percentage and emergence time were significant for each grafting method. Emergent percentage by using the chip budding method was the highest and the emergent time of side grafting was the shortest.
