  • Firmiana pulcherrima Hsue is a plant of genus Erythropsis in family Sterculiaceae,and it is of high ornamental value for landscaping in urban garden and greening. F. pulcherrima Hsue was cultured on seven different substrates: sand,loam,coconut coir,sand + loam（ 1 ∶ 1）,sand + coconut coir（ 1 ∶ 1）,loam + coconut coir（ 1 ∶ 1） sand + loam + coconut coir（ 1 ∶ 1 ∶ 1） to investigate the influence of the substrates on the seed germination and seeding growth of F. pulcherrima Hsue for selection of optimum substrate for F. pulcherrima Hsue. The results showed seeds cultured on the sand gave a germination rate and a germination vigor of up to 55. 6% and 66. 7%,respectively,but had a lower seedling survival rate with retarded seedling height and root growth; that the loam treatment gave the lowest seed germination rate and germination vigor; that the coconut coir treatment improved the seedling survival（ as high as 61. 1%）,and that the mixed substrate sand + loam + coconut coir（ 1 ∶ 1 ∶ 1） had optimum seed germination rate and vigor and seedling growth rate with high seedling height and well-developed roots. It is concluded that the mixed substrate is optimum for culture of seedlings of F. pulcherrima Hsue.

Abstract: Firmiana pulcherrima Hsue is a plant of genus Erythropsis in family Sterculiaceae,and it is of high ornamental value for landscaping in urban garden and greening. F. pulcherrima Hsue was cultured on seven different substrates: sand,loam,coconut coir,sand + loam（ 1 ∶ 1）,sand + coconut coir（ 1 ∶ 1）,loam + coconut coir（ 1 ∶ 1） sand + loam + coconut coir（ 1 ∶ 1 ∶ 1） to investigate the influence of the substrates on the seed germination and seeding growth of F. pulcherrima Hsue for selection of optimum substrate for F. pulcherrima Hsue. The results showed seeds cultured on the sand gave a germination rate and a germination vigor of up to 55. 6% and 66. 7%,respectively,but had a lower seedling survival rate with retarded seedling height and root growth; that the loam treatment gave the lowest seed germination rate and germination vigor; that the coconut coir treatment improved the seedling survival（ as high as 61. 1%）,and that the mixed substrate sand + loam + coconut coir（ 1 ∶ 1 ∶ 1） had optimum seed germination rate and vigor and seedling growth rate with high seedling height and well-developed roots. It is concluded that the mixed substrate is optimum for culture of seedlings of F. pulcherrima Hsue.
