Abstract:
Yunnan is rich in plant resources, there are variety of edible wild forest vegetables for local people in different climatic zones. In order to utilize and develop the forest vegetable resource effectively, breeding experiments of forest vegetable varieties should be carried out gradually. Taking perennial tree shoots(two-year) of wild Trevesia palmata as cuttings, comparative trails of cutting survival rate were carried out in terms of composite substrate, mixed plant rooting agents, soaking time, and cutting seasons. It aims to explore the effects of different treatments on averaging rooting, rooting length and rooting rate of Trevesia palmata. The analysis of cutting trials showed that the best treatment was the composite substrate consists of humus soils, mountain sand, peat soil, vermiculite, and sermented shredded stalk, the volume ratio was 3∶3∶2∶1∶1. The mixed rooting agents include 0.002% α-Naphthylacetic acid, 0.002% naphthalene acetamide, and 0.001% sulfocarbamide, the ratio was 1∶1∶1. After soaking in the mixed rooting agents for 5 minutes, the perennial tree shoots(two-year) of wild Trevesia palmata were cutting propagated. After 50 days of cutting propagation, the average rooting number reaches 5.87, the rooting length was 8.28 cm, and the rooting rate was 80.16%.
