Germination percentage (GP) is normally very low in Cycas revoluta seeds. In an effort to improve germination, omission of seed
dormancy and acceleration of sexual propagation, sulfuric acid (H2SO4
) (0, 10, 25 and 50%) and hot water (60, 80 and 100°C)
pretreatments for different lengths of time were tested. An experiment was carried out using a factorial randomized complete block
design (RCBD). Based on statistical analysis, significant differences were observed between various levels of sulfuric acid and hot
water on germination at 5% level of probability. The highest acceleration of seed germination (171.3 days) was recorded in seeds
pretreated with hot water at 80°C for 12 h. The most germination rates (GR) (95%) and germination value (GV) (44.47) were
obtained in seeds pretreated with hot water at 100°C for 1 h along with 25% sulfuric acid for 2 h.
