通过对感染和未感染内生真菌Neotyphodium starrii高羊茅植株光合特性和形态变化的测定,研究了内生真菌感染对高羊茅的影响.结果表明:感染内生真菌的高羊茅植株净光合速率(P_n)、蒸腾速率(T_r)、水分利用效率(ρWUE)、细胞间CO_2浓度(C_i)、气孔导度(G_s)都高于非感染高羊茅植株,高温下光合性能和抵抗高温的能力都优于非感染高羊茅植株.感染植株和非感染内生真菌植株形态变化表现出一定规律性,感染植株叶片厚,植株高大、叶色深、叶片宽;而非感染植株叶片薄,植株矮、叶色浅、叶片窄.具有良好抗性和适应性的新的草坪草种的选育,可为水资源短缺城市、干旱、半干旱地区及特殊立地条件地区的绿化提供解决问题的新思路.

Photosynthetic and morphological characteristics of endophyte Neotyphodium starrii infected and free tall fescue plants were determinated in the study. The results show that : net photosynthetic rate (P_n), transpiration rate (T_r), water use efficiency (ρWUE), intercellular carbon dioxide concentration (C_i) and stomatal conductance (G_s) of Neotyphodium typhinum infected tall fescue plants were all higher than Neotyphodium typhinum free tall fescue plants; photosynthetic performance under high temperature and the ability to resist high temperatures of infected tall fescue plants were superior to Neotyphodium typhinum free tall fescue plants. Endophyte Infected and free tall fescue plants showed some morphological changes in regularity, endophyte infected ones showed thick leaves, tall plants,deep color, wide leaves; and endophyte free ones showed thin leaf, short plants, light color, narrow leaves. These conclusions provide a new idea for breeding of new turf grass species with good resistance and adaptability, and provide a new method to solve the problem for urban afforestation with water shortage, and for greenery of drought areas, semi-arid areas and special site conditions.
