分别以栽培和野生条件下的九龙山榧(Torreya jiulongshanensis)(雌、雄株)及同属广布种——榧树(T.grandis)为材料,比较了其叶片叶绿素荧光参数对光强的响应,以期为九龙山榧种质资源保育提供科学依据。结果表明,栽培条件下,九龙山榧雌株幼苗叶片的光系统I最大荧光值整体高于榧树及九龙山榧的雄株;九龙山榧雌、雄株幼苗的光饱和点也较高,分别为788.581和550.640 μmol/(m2·s),所对应的最大电子传递速率也较高,分别为40.690和39.546 μmol/(m2·s)。同样,在野外条件下,九龙山榧雌、雄株的光饱和点也均显著高于榧树,分别为1 165.361和1 416.817 μmol/(m2·s),光系统II最大电子传递速率也以九龙山榧雌株为最高,其值为80.322 μmol/(m2·s)。由此可见,九龙山榧为阳生树种,且与榧树相比具有更强的光合潜力。

In order to provide scientific basis for the conservation of Torreya jiulongshanensis germplasm resources,response of chlorophyll fluorescence parameters of T.jiulongshanensis(male and female) and its widespread congener T.grandis leaves(under cultivation and field conditions,respectively) to light intensity are compared in this paper.The results show that,under cultivation conditions,the maximum fluorescence value of photosystem I of female seedlings of T.jiulongshanensis is higher than that of male seedlings and T.grandis.The light saturation points of female and male seedlings of T.jiulongshanensis are 788.581 and 550.640 μmol/(m2·s),respectively,and the corresponding maximum electron transfer rates are 40.690 and 39.546 μmol/(m2·s),respectively.Similarly,under field conditions,the light saturation points of female and male plants of T.jiulongshanensis are significantly higher than those of T.grandis,which stand at 1 165.361 and 1 416.817 μmol/(m2·s),respectively.The maximum electron transfer rate of photosystem II of female plants of T.jiulongshanensis is the highest,which is 80.322 μmol/(m2·s).Therefore,T.jiulongshanensis is a sunny tree species and has stronger photosynthetic potential than T.grandis.
