CONSUMERS AFFECT PREY BIOMASS AND DIVERSITY THROUGH RESOURCE PARTITIONING

Ecology, 2007
Consumer presence and nutrient availability can have contrasting and interactive effects on plant diversity. In a factorial experiment, we manipulated two levels of nutrient supply and the presence of two moderately specialized grazers in different combinations (no grazers, two species in monoculture, and both in combination).

Development of a partitioned-biomass model for rooted macrophyte growth

Aquatic Botany, 1997
Abstract Many surface waters support excessive growth of several rooted macrophyte species. This paper presents a macrophyte growth model to facilitate modeling the growth of several macrophyte species which exhibit distinct patterns of growth and development.

Biomass partitioning in twoCalamagrostis villosa stands on deforested sites

Folia Geobotanica et Phytotaxonomica, 1989
Calamagrostis villosa stands occurring in areas deforested by air-pollution impact in the Moravian-Silesian Beskydy Mountains were characterized by a high dry mass of total underground biomass (3 300 g. m−2—the slope site, 2 850 g. m−2—the flat site).

Growth and biomass partitioning in zinc‐toxic bush beans

Journal of Plant Nutrition, 1988
Abstract Bush bean plants (Phaseolus vulgaris L.) were grown during the exponential growth phase in nutrient solution containing 2, 6.6, 9.6 or 13.5 μM Zn. At six different harvest intervals samples were taken for dry weight and Zn content determinations.

On the Allometry of Biomass Partitioning and Light Harvesting for Plants with Leafless Stems

Journal of Theoretical Biology, 2002
Prior explicit allometric models are extended to predict the scaling relationship between the ability of plants with leafless stems to harvest sunlight H and total standing plant biomass M(T) (which equals the sum of standing stem and root biomass, M(S) and M(R)).

Improving biomass production and partitioning in sugarcane: theory and practice

Field Crops Research, 2005
Abstract Sucrose yields in sugarcane (Saccharum spp.) could be improved by increasing the efficiency of biomass production per unit of intercepted radiation and/or by increasing the fraction of total biomass partitioned to stalk sucrose, or both.

Abscisic Acid and Biomass Partitioning in Tomato Under Salinity

2012
Increasing soil salinization is an enormous cause of crop productivity reduction in many areas of the world. It has a deep backlash on crop yields because it reduces leaf growth and induces leaf senescence, this in turn reduces plant assimilation activity, impairing its capacity for producing further growth or harvestable biomass.

Biomass and nitrogen partitioning during crop growth

2010
Sumary of the book : Rich in bibliographic references, this book presents the current status of knowledge on the physiology of the pea crop. It draws on contributions from plant physiologists and researchers in various other disciplines who have been working together for many years on the production of plants rich in proteins.

Macronutrient accumulation and partitioning in sugarcane biomass grown in the Burdekin region

Sugar Industry international
Understanding of how nutrients accumulate and partition in sugarcane is important for fine-tuning fertiliser recommendations to improve nutrient-use efficiency in a profitable, productive and ecologically sustainable farming system. The commercial sugarcane varieties Q253, Q208 and KQ228, which are grown in the Burdekin, were sampled several times ...
