Plant size and intraspecific variability in vascular epiphytes
… establishment of mechanistic explanations for plant distributions in time and space. The important, albeit mostly ignored, question arises as to the nature of the organisms that should be used as representative in pertinent experiments. I suggest that it is essential to use a “demographic …

The influence of plant size and fertilization on catkin production in birch (Betula pubescens Ehrh.)
… factors influencing these processes is of value. Plant seed production is affected by a number of factors, including nutrient availability, moisture supply, weather conditions, plant density and predation. The main objective of this project is to assess the effects of plant size and fertilization …

Flowering Control and Production of Strobilanthes dyerianus Mast. (Persian Shield)
… dyerianus is a popular bedding and container plant. A problem in production is that over-wintered stock plants often flower. Once the plant becomes reproductive, stem elongation slows and floral buds arise from every node, rendering the plants useless for propagation. The objectives of this …

Ecology of flowering and fruiting in Lotus corniculatus L.
… material is fundamentally self-incompatible. Plants in Upper Seeds are larger than in Lower Seeds Reserve. Comparative data on soil nutrients in the two sites suggests that the cause is the persistence of phosphorus from inorganic fertiliser. There is a positive, linear relationship between …

Effects of arbuscular-mycorrhizal fungal colonization on management of saline lands
… of arbuscular-mycorrhizal ( AM ) colonization of plants in management of saline lands. Some aspects of application of AM fungi in revegetation of saline lands are also reported. Effects of AM pre-inoculation on mycorrhiza-responsive and non-responsive plant growth and establishment were evaluated …

Soybean growth and yield response to interplant competition relief in various plant density environments
… component production in response to changes in plant population and competition. Previous research has addressed these issues from various aspects, however, there is a lack of information regarding how interplant competition affects plant size variability, or how different sized plants respond …

Effect of size of delivery and type of market outlet on cost of delivering table eggs by selected egg grading plants in Virginia
… were obtained. Cost comparisons were made by size of plant, size of delivery and type of outlet. Wide variation in delivery costs were found. Delivery costs showed a meaningful decline as volume of delivery increased. Significant differences in delivery costs among different types of market …

Environmental Gradients Impact Key Leaf Traits in Riparian Trees
<p>Specific leaf area (SLA) reflects a plant’s carbon investment per area and relates to generalized leaf economics spectrum growth strategies (LES). To fill gaps of knowledge about intraspecific SLA variation and why it is often inconsistent with the LES, we studied the response of two riparian …

Economies of scale analysis and location studies for fuel ethanol refineries
… AUF values for feedstock procurement. However, plant location can greatly impact feedstock procurement cost. In addition, it is difficult to estimate biomass feedstock costs, since no large-scale commercial markets exist. It is, therefore, not easy to make plant siting decisions, as several …
