“…Shading reduced photosynthesis due to increase in stomatal and mesophyll resistance, transpiration, partitioning of biomass from vegetative parts to economic parts (Nygren and Killomaki, 1993). General adaptive responses of crop plant to low irradiance are the increase in leaf area ratio, chlorophyll content, leaf to stem mass and stem length and decrease in leaf thickness (Fujita et al, 1993;Singh, 1994).…”

An experiment was carried out to evaluate the leaf characteristics and yield performances of mungbean (Vigna radiata L.) under different light levels at the Crop Physiology and Ecology Research Field of Hajee Mohammad Danesh Science and Technology University, Dinajpur during March to June 2016. The experiment was laid out in a split plot design with three replications. Three light levels (L 100 -100 % light intensity, L 75 -75 % light intensity and L 50 -50% light intensity) were assigned in the main plots and four varieties (BARl Mung-6, BINA Mung-8, BINA Mung-5 and BU Mug-4) were assigned in subplots. Mosquito nets of different pore size were used for maintaining 75 and 50 percent light intensity. Leaf area was increased due to reduced light levels in all mugbean varieties but the increment was significant in BINA Mung-5 and BINA Mung-8 only at 75% light intensity at 40 days after sowing and only in BARI Mung-6 with L 50 and BU Mug-4 with L 75 and L 50 at 50 days after sowing. Due to reduced light levels, leaf dry weight was affected more in BINA Mung-5 and BU Mug-4 than BARI Mung-6 and BINA Mung-8. Leaf thickness was reduced under shade in all the mungbean varieties, except in BU Mug-4 at 75% light intensity, and the reduction in leaf thickness was mainly due to the reduction in thickness of spongy layer. The palisade layer thickness was influenced insignificantly but spongy layer thickness was increased in BINA Mung-5 at 100% light intensity. The grain yields (t ha , and heavier grains in BARI Mung-6 and BINA Mung-8 contributed to the higher grain yield plant -1 under partial shade condition than in BINA Mung-5 and BU Mug-4.

“…V. M iller 1999). Leaf area index (LAI ) (square meters of leaf area per square meter of ground area) of kudzu can exceed 8 (Fujita et al 1993), resulting in dense shade capable of absorbing almost all direct solar radiation incident on a given site. As it switches from a prostrate to a climbing growth habit, kudzu shifts its priority of carbon allocation from growth of primary branches to growth of the main stem (Tsugawa et al 1992).…”

“…Although it thrives best under full-sunlight conditions, kudzu is considered to be moderately tolerant to shade (Fujita et al 1993). To achieve 90% of its maximum photosynthesis rate, kudzu plants need 860 mmol m 2 2 s 2 1 of photosynthetic photon¯ux density (C arter and Teramura 1988).…”

Kudzu (Pueraria montana) community responses to herbicides, burning, and high-density loblolly pine

K udzu is an aggressive, nonnative vine that currently dominates an estimated 810,000 ha of mesic forest communities in the eastern United States. To test an integrated method of weed control, abundances of kudzu and other plant species were compared during 4 yr after six herbicide treatments (clopyralid, triclopyr, metsulfuron, picloram 1 2,4-D , tebuthiuron, and a nonsprayed check), in which loblolly pines were planted at three densities (0, 1, and 4 seedlings m 2 2 ) to induce competition and potentially delay kudzu recovery. T his split-plot design was replicated on each of the four kudzu-dominated sites near Aiken, SC . R elative light intensity (R LI ) and soil water content (SW C ) were measured periodically to identify mechanisms of interference among plant species. Two years after treatment (1999), crown coverage of kudzu averaged , 2% in herbicide plots compared with 93% in the nonsprayed check, and these differences were maintained through 2001, except in clopyralid plots where kudzu cover increased to 15%. In 2001, pine interference was associated with 33, 56, and 67% reductions in biomass of kudzu, blackberry, and herbaceous vegetation, respectively. R LI in kudzu-dominated plots (4 to 15% of full sun) generally was less than half that of herbicide-treated plots. SW C was greatest in tebuthiuron plots, where total vegetation cover averaged 26% compared with 77 to 111% in other plots. N one of the treatments eradicated kudzu, but combinations of herbicides and induced pine competition delayed its recovery.

“…In wooded agroecosystems, such as agroforestry systems, light restriction may influence the productivity of certain species (Cavatte et al 2012, Chauhan 2013, however, this effect does not occur in N. wightii and P. phaseoloides. Fujita et al (1993) observed an increase in the P. phaseoloides maintained under 55% shade, emphasizing the potential of this species for cultivation under restricted sunlight. Such observations highlight the importance of using these species in silvopasture systems, as good root development under low light intensity is directly associated with persistence and good yield in pastures (Oliveira and Solto, 2003).…”

Plants have the ability to undergo morphophysiological changes based on availability of light. The present study evaluated biomass accumulation, leaf morphoanatomy and physiology of Neonotonia wightii and Pueraria phaseoloides grown in full sunlight, as well as in 30% and 50% shade. Two assays were performed, one for each species, using a randomized block design with 10 replicates. A higher accumulation of fresh mass in the shoot of the plants was observed for both species under cultivation in 50% shade, while no differences were detected between the full sunlight and 30% shade. N. wightii and P. phaseoloides showed increase in area and reduction in thickness leaf when cultivated in 50% shade. There were no changes in photosynthetic rate, stomatal conductance, water use efficiency and evapotranspiration of P. phaseoloides plants because growth environment. However, the shade treatments caused alterations in physiological parameters of N. wightii. In both species, structural changes in the mesophyll occurred depending on the availability of light; however, the amount of leaf blade tissue remained unaltered. Despite the influence of light intensity variation on the morphophysiological plasticity of N. wightii and P. phaseoloides, no effects on biomass accumulation were observed in response to light.
