The combined effects of ozone, sulfur dioxide and simulated acid rain on the growth of three forest tree species
… and white ash were exposed to various concentrations of O₃ (0.00 to 0.15 ppm) and/or SO₂ (0.08 ppm), 4 hr/d, 5d/wk in combination with simulated rain (pHs 5.6, 4.3, 3.0), 1 hr/d, 2 d/wk, for 5 or 6 wk under controlled laboratory conditions. Pollutant exposures resulted in alterations in …

The effects of rhizosphere inundation on the growth and physiology of red maple (Acer rubrum L.) seedlings derived from wet and dry sites
… However, flooding significantly decreased leaf, stem, and root dry matter accumulation as well as height growth, leaf area growth, root to shoot ratio, mean relative growth rate, net assimilation rate, and mean leaf area ratio. Thirteen days of rhizosphere inundation as well as six days of …

MORPHO-PHYSIOLOGICAL FACTORS AFFECTING PLANT PRODUCTIVITY IN BUSH AND VINE FORMS OF WINTER SQUASH (CUCURBITA MAXIMA DUCH)
… only 52 percent of its mesophyll thickness. Leaf thickness was not found to be significantly different between 'Autumn Pride' and 'Blue Hubbard'.</p><p>Due to its dwarf stem, all 'Autumn Pride' organs were more proximal to their leaves. Furthermore, stems and petioles of 'Autumn Pride' were …

The importance of cotyledon functional morphology and patterns of seed reserve utilization for the physiological ecology of neotropical tree seedlings
… with a larger photosynthetic capacity. Concentrations of energy and nitrogen reserves in seeds vary up to three fold among species and are independent of total seed mass or cotyledon functional morphology. Species with higher energy concentration in seeds transform a unit of seed mass into …

Purple nutsedge (Cyperus rotundus L.) competition with cotton: Species biology and effects of proportion, density, and moisture
… maintain higher RGR (relative growth rate), LAR (leaf area ratio), and leaf expansion than nutsedge. Absolute growth rate (AGR), initial propagule weight, and early shoot production were important parameters for purple nutsedge competition with cotton. Moisture stress affected the relative …

Trait-based approaches to understanding the response of forest understory herbs to environmental variation
… survival; however, plasticity in height, leaf area, and leaf area ratio were strongly related to the growth of surviving transplants. Finally, at the individual level, I found that individual size and soil moisture availability had a positive effect on plant performance such that large …
