“…Rapparini et al (1999) also observed shoot growth inhibition when blue light was associated with a high rate of cycling between red and far-red forms of phytochrome. In contrast, Macedo et al (2010) observed that plants grown under blue light induced a greater number of leaves per plant, and larger leafblade area than those grown under red or green light. Schuerger et al (1997) reported that pepper plants grown under red LED's supplemented with blue light produced thicker leaves than those grown under red alone or red supplemented with far-red LED's.…”

Cascade palms (Chamaedorea cataractarum Mart.) are slow growing, ornamental plants suitable for both indoor and outdoor use. The purpose of this study was to determine effects of colored plastic mulch on the growth of Chamaedorea cataractarum Mart. Seedlings grown in soil were compared with those grown using red and blue plastic much cover. The study was conducted in triplicate settings at two different green houses and at two different locations in one of the green houses. Plant growth was monitored for plant height, stem thickness at the base, number of leaves and leaflets, chlorophyll a and b, root density, root length and shoot dry weight. Data were analyzed in a randomized complete block design. Light reflected from both mulch colors and the bare substrate had low radiance values in the blue, red and far-red wavelengths. Mulch color had a relatively small significant effect on plant height (P = 0.0728). Plants grown on red mulch had smaller height than those grown on bare substrate and on blue mulch. Although the differences were not significant, plants grown on blue mulch had higher growth rates (height, stem diameter), as well as higher number of leaves and leaflets.

“…4D). Light quality also had an impact on leaf anatomy (Macedo et al, 2011;Wu et al, 2014). Our research showed that plants grown under R had the thinnest leaves, which might be caused by the decreased length of palisade and spongy tissue (Fig.…”

Light quality can influence the photosynthetic characteristics, morphology and physiological processes of plants. To investigate the effects of different light qualities (white light, W; red light, R; blue light, B; mixture of red and blue light, RB) of light emitting diodes (LEDs) and white cold fluorescent lamp on the growth and morphology of fruiting mulberry plants (Morus alba L. cv. 'Longsang No.1'), fruiting mulberry plants were grown under different light qualities: W, R, B and RB of the same photosynthetic photo flux density (PPFD; 100 μmol m -2 s -1 ) for 20 d. Our results showed that stem length and leaf area of plants grown under R were the highest. However, stem length and leaf area of plants grown under B were lowest. Dry weights (DW), leaf mass per area (LMA), chlorophyll a/b ratio, soluble protein content, sucrose and starch content, and total leaf nitrogen (N) content of plants grown under R were the lowest. Net photosynthetic rate (Pn), stomatal conductance (gs), and actual photochemical efficiency of PSII (ΦPSII) of plants grown under RB were similar to plants grown under W. Net photosynthetic rate (Pn) and ΦPSII of plants grown under R and B were lower than plants grown under W and RB. Antioxidant enzymes activity of plants grown under R, RB and B were higher than plants grown under W. The number of leaf stomata, leaf thickness, palisade tissue length and spongy tissue length were the lowest in plants grown under R. The number of leaf stomata, leaf thickness and palisade tissue length of plants grown under RB and B were higher than plants grown under R. The results of this study indicate that a certain ratio of mixed red and blue LEDs light can reduce adverse effects of monochromatic red and blue LEDs light on fruiting mulberry growth and development.

“…The main factor that can affect to plant growth is light, it related to photosynthesis process in the plant (Zervoudakis et al, 2012). The intensity of the light is important for growth, morphogeneis and other physiological responses (Hogewoning et al, 2010;Macedo et al, 2011).…”

Asteraceae family has various benefit as herbal medicine and phytochemical affect (biopesticides). It can grow in different habitats but the morphological and physiological characters of Asteraceae depend on the environmental factor. The aims of the study is to describe the variation of height of stems and width of leaves from three species of Asteraceae family (Pluchea indica, Ageratum conyzoides and Elephantopus scaber), on three types of habitat which differed by its altitude and learn the correlation between altitude and morphological characteristics of Asteraceae. Samples of Asteraceae were obtained from Bangkalan-Madura The habitat altitude and the environmental factors were determined by measuring altitude, light intensity, oxygen levels (climate), organic compound, C level, N level, pH (soil chemical character), soil temperature, water levels, porosity, dust, sand and soil humidity (soil physical character). Asteraceae which grows at intermediate-altitude has the highest stems. While, Asteraceae at low-altitude has the widest leaf.
