Abstract
Controlled-environment germination studies showed that the optimum temperature for germination of Kikuyu grass seed was within the range 19-29 deg C. When germination rate was considered, the optimum temperature was 29 deg . Exposure of imbibing seeds to a temperature of 44 deg for periods of >12 h resulted in a lower germination index, but exposure of up to 48 h had no significant effect on final germination. Under non-limiting moisture and temperature conditions, emergence from a depth of 3 cm was significantly lower than from 0 or 0.5 cm. Kikuyu grass seedlings showed a marked response to both N and P. Surface-sown seeds failed to germinate under surface-drying conditions. There was no significant difference in emergence rates from depths ranging from 0.7 to 5.6 cm when seeds of cv. Whittet were used, but emergence rates of cv. Breakwell from depths of 2.8 and 5.6 cm were significantly lower than from depths of <2.8 cm.ADDITIONAL ABSTRACT:Controlled cabinet germination studies have shown that the optimum temperature for germination of kikuyu grass (Pennisetum clandestinum) seed was within the range 19-29 deg C. Under non-limiting moisture and temperature conditions emergence from 3 cm was significantly lower than from 0 cm and 0.5 cm. Kikuyu seedlings showed a marked response to both nitrogen and phosphorus. Under surface-drying conditions surface-sown seeds failed to germinate. There was no significant difference in emergence rates from depths ranging from 0.7 cm to 5.6 cm with the cultivar Whittet. With Breakwell, emergence rates from 2.8 cm and 5.6 cm were significantly lower than from depths less than 2.8 cm.
