Abstract:To understand performance of lavender in high altitude area of Yichang, used Lavandula angustifolia 'French Blue' as the material, 9 agronomic traits were measured, including plant height, crown width, number of heads, average length of inflorescence, average number of layers in inflorescence, average number of flowers in inflorescence, average diameter of corolla, number of flowers per plant and flowering period, and the meteorological factors were recorded. One-way ANOVA and Pearson correlation analysis were performed. The results indicated that the variation coefficient of 9 agronomic traits was ranged from 2.45% to 50.95%, and there were significant differences(p<0.05) in agronomic traits of lavender in different years except the average diameter of corolla. There were correlations between flower number and plant height, crown width and head number; and the average number of layers in inflorescence and the average number of flowers in inflorescence were significantly negatively correlated with the annual rainfall. In the process of lavender cultivation, the biomass of lavender can be increased by optimizing cultivation measures, and the average layers number of inflorescence and the average number of flowers can be increased by controlled water cultivation, so as to improve the flower number and the ornamental value of lavender.
