“…SLA and LAR are also very plastic growth traits which are strongly affected by photon supply (Jeangros and Nösberger 1992). Decreasing irradiances cause the increase of SLA and LAR with the result that photon capture by the leaves is increased (Semb 1996). In present study, irradiance strongly affected photosynthetic and growth characteristics of M. chinensis and M. scabra, plants grown at lower irradiances had lower P max , SI, CI, and B and higher SLA and LAR.…”

Photosynthetic and growth characteristics of Mosla chinensis and M. scabra were compared at three irradiances similar to shaded forest understory, forest edge, and open land. At 25 % full ambient irradiance, M. chinensis and M. scabra had similar photosynthetic characteristics, but saturation irradiance, compensation irradiance, and apparent quantum yield of M. chinensis were higher than those of M. scabra at full ambient irradiance and 70 % full ambient irradiance. At the same irradiance treatment, specific leaf area and leaf area ratio of M. chinensis were lower than those of M. scabra. Photon-saturated photosynthetic rate and water use efficiency of M. chinensis, however, were not significantly higher than those of M. scabra, and the leaf area and total biomass were lower than those of M. scabra. As a sun-acclimated plant, the not enough high photosynthetic capacity and lower biomass accumulation may cause that M. chinensis has weak capability to extend its population and hence be concomitant in the community.

“…These are very plastic growth traits and often strongly affected by irradiance (Jeangros and Nosberger 1992, Sakai 1995, Pothier and Prevost 2002. A decreasing irradiance causes an increase in LAR with the result that radiation captured by leaves increased (Semb 1996). Under a high irradiance, an increased LMA is associated with an adaptation to the high irradiance but it may be a result of adjustment to changes of temperature and humidity as well (Boardman 1977).…”

Growth, photosynthetic characteristics, chlorophyll (Chl) fluorescence parameters, and peroxidation of membrane lipid of Cryptotaenia japonica were studied under differing irradiances (15, 35, 60, and 100 % of full irradiance). At full irradiance, C. japonica exhibited a typical decline in net photosynthetic rate (P N ) at midday, which was not observed in the other irradiance treatments. This indicates a possible photoinhibition for C. japonica at the high irradiance. Diurnal patterns of stomatal conductance (g s ) were remarkably similar to those of P N in each irradiance treatment, and the intercellular CO 2 concentration (c i ) had the opposite trend. C. japonica growing under 60 % of the full irradiance exhibited the highest plant height, stem diameter, leaf area, and biomass. The initial fluorescence (F 0 ) value was lowest at 60 % of the full irradiance. Maximal fluorescence (F m ), potential activity of photosystem II (PS II) (F v /F 0 ), and maximal photochemical efficiency of PS II (F v /F m ) values were highest at 60 % of full irradiance and lowest at 15 % of the full irradiance. The malondialdehyde (MDA) content in 15 % and 100 % of the full irradiance were higher than under the other irradiances. During the treatment, catalase, peroxidase, and superoxide dismutase activities firstly increased and then declined under 15 % and 100 % of the full irradiance and were steadily low under 60 % of the full irradiance, indicating a low production of reactive oxygen species. Therefore, C. japonica thrived best under 60 % of the full irradiance.

The effects of shade on the growth, leaf photosynthetic characteristics, and chlorophyll (Chl) fluorescence parameters of Lycoris radiata var. radiata were determined under differing irradiances (15, 65, and 100% of full irradiance) within pots. The HI plants exhibited a typical decline in net photosynthetic rate (P N ) during midday, which was not observed in MI-and LI plants. This indicated a possible photoinhibition in HI plants as the ratio of variable to maximum fluorescence (F v /F m ) value was higher and the minimal fluorescence (F 0 ) was lower in the , and LI plants. Diurnal patterns of stomatal conductance (g s ) and transpiration rate (E) were remarkably similar to those of P N at each shade treatments, and the intercellular CO 2 concentration (C i ) had the opposite change trend. Under both shading conditions, the light saturation point, light compensation point and photon-saturated photosynthetic rate (P max ) became lower than those under full sunlight, and it was the opposite for the apparent quantum yield (AQY). The higher the level of shade, the lower the integrated daytime carbon gain, stomatal and epidermis cell densities, specific leaf mass (SLM), bulb mass ratio (BMR), leaf thickness, and Chl a/b ratio. In contrast, contents of Chls per dry mass (DM), leaf area ratio (LAR), leaf mass ratio (LMR), leaf length, leaf area and total leaf area per plant increased under the same shade levels to promote photon absorption and to compensate for the lower radiant energy. Therefore, when the integrated daytime carbon gain, leaf area and total leaf area per plant, which are the main factors determining the productivity of L. radiata var. radiata plant, were taken into account together, this species may be cultivated at about 60~70% of ambient irradiance to promote its growth.
