阳江5种滨海园林植物的光合特性和叶片元素
|
摘要
对阳江5种园林植物的光合特性和叶片元素状况进行了研究。结果表明,园林植物的净光合速率为马鞍藤>花叶假连翘>银边山菅兰>鹅掌藤>朱蕉,花叶假连翘和马鞍藤的光合能力最强。海陵岛植物叶片的C、N、P、K和Na含量范围分别为457.8~503.6、11.6~33.3、1.2~2.7、14.4~21.7和0.7~8.1 g·kg-1。花叶假连翘的叶片N、P和K含量最高,马鞍藤次之。5种园林植物的C:N和C:P范围分别为13.8~43.4和171.8~380.9,N:P范围为7.6~12.5,N:K和K:P范围分别为0.8~1.5和8.1~11.8。聚类分析表明,5种园林植物中,花叶假连翘和马鞍藤的叶片养分含量高,促进了光合作用。
The photosynthetic characteristics and nutrient contents in garden plant leaves of five species were studied in Yangjiang, Guangdong Province. Results showed that net photosynthetic rate of the garden plants decreased in the order of Ipomoea pes-caprae > Duranta repens ‘Variegata'> Dianella ensifolia‘White Variegated'> Schefflera arboricola > Cordyline fruticosa, and photosynthetic abilities of I. pes-caprae and D. repens were the strongest among garden plants of the fives species. The contents of C, N, P K and Na in the plant leaves ranged from 457.8-503.6, 11.6-33.3, 1.2-2.7, 14.4-21.7 and 0.7-8.1 g·kg-1, respectively. N, P and K contents in I. pes-caprae were the highest and those in D. repens ranked the second among garden plants of the fives species. The values of C: N and C: P in the garden plants ranged from 13.8-43.4 and 171.8-380.9, respectively. N:P ranged from 7.6-12.5, whereas N:K and K:P ranged from 0.8-1.5 and 8.1-11.8, respectively. The photosynthetic indexes and leaf nutrients of the garden plants were used for cluster analysis, and the results indicated that nutrient contents in I. pes-caprae and D. repens were high, which could promote their photosynthesis.
