Abstract: In order to investigate the growth difference by use of different artificial cultivation models of Lilium regale Wilson which were planted in Chengdu Plain climate conditions. The 6-year-old seedlings were selected as the experimental materials, which were planted by use of four different cultivation models, i.e. ground seedbed in the sunlight greenhouse (PD), nutrition pot in the sunlight greenhouse (PB), outdoor field (LD), and nutrition pot in the outdoor field (LB). Phenology and 11 growth indexes were determined. The correlation analysis and principal component analysis were used to study the interrelation among the 11 growth indexes and comprehensively evaluate the four different cultivation models. The results showed that (1) the phenology before fruit ripening of PD and PB was earlier than that of LD and LB, but the opposite pattern was observed in fruit ripening and withering phenology. Among all the models, PB showed the earliest sprouting and pod ripening phenology, PD had the earliest flowering phenology, and LD has the earliest withering phenology; (2) all the tested 11 growth indexes, such as the ground diameter, plant height and number of flowers per plant showed significant differences (p<0.01) by use of different cultivation models. The number of flowers per plant had the highest coefficient of variation, reaching 427.00%, and the flower diameter had the lowest coefficient of variation, reaching 9.67%; (3) all the 11 growth indexes of Lilium regale by use of four cultivation models showed positive correlation with each other, and the correlation of multiple indexes reached extremely significant level (p<0.01); (4) the principal component analysis of 8 selected indicators showed that the comprehensive score ranking was PD>LD>LB>PB, PD was the best for the growth of Lilium regale.
