Study on Seed Germination Rate of New Zealand Rose
New Zealand rose seed was experimented,observed the seed morphology; determined thousand seed weight, plumpness and kernel rate; and analyzed germination rate,germination potential and germination index of the seeds of different stratification. The result were discovered: New Zealand rose seeds is triangular prismatic shape; yellowish white skin,smooth slightly lines epidermis;seed of 0.397cm average length,0.113cm average thickness,8.819g average grain weight. In soil fertility and moisture adequate conditions,plumpness of New Zealand rose seed reached 78.5%,kernel rate of that was 96.9%. The best stratification treatment of New Zealand rose seed was for 140d under the condition of 0-4℃after 30℃warm water immersion.
