Abstract
|
|
|
|
Germination responses to the treatments of stratification at 5℃ (chilling), Gibberellin (GA), kinetin, and light under different temperatures were studied using the seeds of two clones of native Actinidia arguta. Seed germination increased cumulatively up to 4 weeks of chilling without further increase in germination thereafter. Within the range of 20 to 30℃, germination rate was adversely affected by increasing temperature and such inhibition was partially or completely overcome by prolonged chilling or GA. GA at higher concentration, and lower levels of kinetin were effective in enhancing seed germination, but optimal requirements for GA and kinetin differed between two clones tested. Germination rate was improved by light, however GA enhanced the germination in the dark. Treatments with chilling, GA, and kinetin were not effective in enabling the seeds of low density ($lt;1.0gcm^(-3)) to germinate.
