Dormancy and germination characteristics of Tarenaya hassleriana (Cleomaceae) seeds

Abstract: Elucidating the physiological and ecological mechanisms of seed dormancy germination is great significance for species conservation application plant resources. Based on Baskin Baskin’s classification system dormancy, cause in Tarenaya hassleriana (Cleomaceae) seeds was studied using alternating temperature, cold moist stratification, dry storage, GA3 soaking treatment. The results indicated that fresh mature T. had a combinational including physical type 2 non-deep were photoblastic, with an optimal temperature 35°C. In addition, may be efficiently released from promoted to germinate by 20 °C/30 °C, stratification following storage. Furthermore, treatment could also promote release subsequent at 35 storage 5-15 °C. These suggested there complex cross-talks among phytohormone, osmotic potential, signaling regulatory pathways during seeds, which deserve further study.
