Leaf size indices of the tree species in the peatland of Agusan del Sur in Mindanao in Philippines was examined to deduce the variation of forest structure and observed forest zonation.  Using raunkiaer and webb’s leaf size classification, the leaf morphometrics of seven tree species consistently found on the established sampling plots were determined.  The species includes Ternstroemia phi...

One of the most important pollution in world is air pollution. factors that cause this vehicles. Heavy metals have a great role component caused by vehicles and they negative effects on plant human health. In study, it was aimed to determine effect distance from highway leaf morphology anatomy economically Red Globe grape variety. Leaf samples were collected four different distances (road side,...

this study was undertaken to identify morphological changes in young seedlings of 5 iranian almond species (prunus dulcis, p. eburnea, p. eleagnifolia, p. haussknechti, and p. scoparia) under polyethylene glycol-induced drought stress. drought stress caused a significant reduction in plant growth parameters such as fresh and dry weights of plant organs, leaf number, total leaf area, and leaf re...

The breeding of wheat with greater early vigour has potential to increase water- and nutrient-use efficiency, as well as to improve weed competitiveness to raise crop yields profitably. Given that wheat is inherently conservative in its early growth, a sustained breeding effort was initiated to increase genetically seedling leaf area in developing novel high vigour germplasm. A recurrent select...

In this research, leaf area prediction model was developed for some leaf-used maize (Zea mays L.) cultivars namely Coluna, Luce, Maveric, Ranchero, TTM-813, Zamora and RX-788 grown in Black Sea region of Turkey. Lamina width, length and leaf area were measured without destroying the leaf to develop the models. The actual leaf areas of the plants were measured by PLACOM Digital Planimeter and mu...

Seagrasses are often regarded as climate change ‘winners’ because they exhibit higher rates of photosynthesis, carbon fixation and growth when exposed to increasing levels of ocean acidification. However, questions remain whether such growth enhancement compromises the biomechanical properties of the plants, altering their vulnerability to structural damage and leaf loss. Here, we investigated ...

BACKGROUND AND AIMS Leaf thickness plays an important role in leaf and plant functioning, and relates to a species' strategy of resource acquisition and use. As such, it has been widely used for screening purposes in crop science and community ecology. However, since its measurement is not straightforward, a number of estimates have been proposed. Here, the validity of the (SLA x LDMC)(-1) prod...

purpose : to evaluate the correlation between inner segment/outer segment (is/os) line and external limiting membrane (elm) layer integrity at foveal center and visual outcome and to investigate the prognostic factors in optical coherence tomography (oct) that related to final visual acuity (va) and recovery time in acute central serous chorioretinopathy (csc) methods : we prospectively studied...

The effects of a heavy metal containing wastewater sediment on two cultivars white willow were investigated in pot experiment. Our aim was to examine the effect toxic elements microanatomical parameters leaves tested plant. We examined following parameters: stomatic density, stoma width and length, lamina thickness, adaxial abaxial epidermis mesophyll palisad spongy parenchyma main vein length....
