EFFECTS OF DESICCATION AND TEMPERATURE ON SURVIVAL OF CYPERUS ESCULENTUS TUBERS AND CYNODON DACTYLON RHIZOMES.

- Abstract
The effects of all combinations of five desiccation treatments, two temperatures and three durations of desiccation on the survival of <em>Cyperus esculentus</em> tubers and two-node <em>Cynodon dactylon</em> rhizome fragments were examined in laboratory and glasshouse experiments. <em>Cyperus esculentus</em> tuber survival was greater at 22° C than at 4° C. Duration of desiccation did not influence tuber survival, except at the lower temperature. Survival of <em>Cynodon dactylon</em> rhizome fragments was greatly influenced by desiccation treatment, duration of desiccation and the interaction of these two factors. No buds survived when rhizomes reached 50% of their original weight, indicating good tolerance of desiccation since the original dry-matter content of rhizomes in this experiment was 41.2%.
