Effects of storage period and temperature on seed germination of selected Nigerian mahogany species

Abstract

A 3 x 3 factorial experiment in a completely randomized design was employed to investigate the effects of three storage temperatures on germination of seeds of three Nigerian Mahogany species, namely: Khaya senegalensis, Khaya grandifoliola and Entandrophragma angolense, for a period 9 months, in order to determine the optimal temperature and length of time for storage of these seeds. Freshly processed seeds, sun-dried to moisture content of between 10-12% and stored at three temperature regimes of 28OC + 2OC, 5OC + 2OC and -17OC + 2OC were taken out at monthly intervals and sown. Data collected were subjected to Analysis of Variance (ANOVA) P Keywords : storage period, storage temperature, seed germination. Moor Journal of Agricultural Research Vol. 6 (1&2) 2005 pp. 30-35
