Study on Propagation of Quercus virginiana by cutting
Abstract: In recent years, China is lack of evergreen saline alkali tolerant tree species, has introduced Virginia oak species from the United States for breeding research. This research is mainly about propagation of Quercus virginiana by cutting , to decide the best season of cutting method and pick out the most appropriate hormone proportion and substrate proportion, aimed at the mass propagation of Quercus virginiana. The results show that significant differences of rooting ratio were observed between cutting season,substrate proportion and hormone proportion.The best disposal for cutting propagation was September.The rooting rate, the average rooting length and rooting number is respectively71.52%、16.1cm and 1.4，next is March，its rooting rate, the average rooting length and rooting number is respectively 63.34%、15.5cm and 1.4.The ideal substrate of Quercus virginiana is the ratio of mud-stone,perlite and vermiculite is 6:2:2，its rooting rate, the average rooting length and rooting number is respectively 85.94%、16.7cm and 1.4.Treated with different plant hormone, rooting rate also exists obvious difference.For Quercus virginiana The best disposal for cutting propagation is treated with 4g/L IBA plant hormone,its rooting rate, the average rooting length and rooting number is respectively 64.27%,17.5cm and 1.4.Thus, the best combination of Quercus virginiana treated with 4g/L IBA and the ratio of mud-stone,perlite and vermiculite is 6:2:2 in September for cutting.
Key words: Quercus virginiana; hormone proportion; substrate proportion;cutting season
