| Abstract: | Seedling growth indexes and physiological characteristics among of seven different types of Catalpa bungei for one- year-old langhianensis were studied. The resuks showed that there were significant differences in height, diameter, and length and width of leaf, leaf petiole among different types of Catalpa bungei, respectively. There was an increasing trend in height（25.33 -40. 16 cm） , diameter（4. 62 -6. 29 cm） , and leaf（ 13.79 -15.58 cm）. The content of chlorophyll a, chlorophyll b, and total chlorophyll had a variance too. The single biomass of Catalpa bungei ranged from 497 g to 618 g, and the highest was HUI Catalpa bungei, the least was YU Qiu 2 （ Catalpa bungei）. Fast-growing period of Catalpa bungei was from mid-June to mid-August, lasting for 62 days, |
