SEED STORAGE BEHAVIOUR OF <em>CHUKRASIA</em> <em>TABULARIS</em> AND <em>C</em>. <em>VELUTINA</em>

Abstract

Seeds of Chukrasia tabularis collected in Vietnam and C. velutina collected in Thailand were tested for germination capacity after being subjected to three different storage regimes: at room temperature (23 °C), in the cold room (4 °C) and in the freezer (-16 °C). Results showed that the seeds which were stored under these conditions for up to 40 months maintained a relatively high level of viability irrespective of storage temperature regimes. However, seeds of C. tabularis deteriorated more rapidly when stored at room temperature. After 40 months of storage, seeds of C. velutina had a mean germination capacity of 69.3, 72.0 and 78.7% respectively for room temperature, cold room and freezer storage while those of C. tabularis had a mean germination capacity of 29.3, 58.8 and 58.7% respectively.
