We investigated the physiological effect of night chilling (CN) on potted seedlings of two tropical tree species, Calophyllum polyanthum and Linociera insignis, in Xishuangbanna, southwest China. Seedlings grown under 8, 25, and 50 % daylight for five months were moved to a 4–6 °C cold storage house for three consecutive nights, and returned to the original(More)
We investigated the effect of growth irradiance (I) on photon-saturated photosynthetic rate (P max), dark respiration rate (R D), carboxylation efficiency (CE), and leaf mass per unit area (LMA) in seedlings of the following four tropical tree species with contrasting shade-tolerance. Anthocephalus chinensis (Rubiaceae) and Linociera insignis (Oleaceae) are(More)
We tested the hypothesis that invasive (IN) species could capture resources more rapidly and efficiently than noninvasive (NIN) species. Two IN alien species, Ageratina adenophora and Chromolaena odorata, and one NIN alien species, Gynura sp. were compared at five irradiances. Photon-saturated photosynthetic rate (P max), leaf mass (LMA) and nitrogen(More)
Jatropha curcas, one of the most important energy plant resources, is vulnerable to chilling. To evaluate the effects of chilling on photosynthesis of J. curcas and intraspecific differences in chilling tolerance, seedlings of twelve populations were treated with the temperature of 4–6°C for five consecutive nights with normal environmental temperature(More)
Enemy release hypothesis predicts that alien plants that escape from their natural enemies suffer lower enemy regulation in their introduced ranges than in native ranges. An extension of this theory suggests that if enemy release plays a crucial role in invasive success, then in the introduced range, invasive plants should also suffer lower local enemy(More)
