Biomass turnover in brachiaria cultivars in a tropical environment
Bioscience Journal, 2017 The experiment was conducted to evaluate the morphogenetic traits of three Brachiaria cultivars (common, Llanero and Tupi) subjected to continuous grazing with variable stocking rate in the four seasons of the year.

Growth Rates and Carbohydrate Fluxes within the Elongation Zone of Tall Fescue Leaf Blades [PDF]
Plant Physiology, 1987 Investigations were performed to better understand the carbon economy in the elongation zone of tall fescue leaf blades. Plants were grown at constant 21 degrees C and continuous 300 micromoles per square meter per second photosynthetic photon flux density where leaf elongation was steady for several days.

Agricultural Sciences, 2015 Leaf appearance and leaf elongation rates in rice play an essential role in determining the development of the plants’ architecture which affects their adaptability to varying environments. This study aimed to characterize the rates of leaf appearance and elongation on all leaves of the main culms of rice plants for 11 contrasting varieties and to ...

Mechanical impedance of root growth directly reduces leaf elongation rates of cereals [PDF]
New Phytologist, 1997 SUMMARYA dry soil is generally a hard soil. Thus, the effects of water stress and mechanical impedance on plant growth are difficult to separate. To achieve this we have developed a growth cell that allows manipulation of the strength of growth media (i.e. mechanical impedance) without altering the availability of water or nutrients.

A hydraulic model is compatible with rapid changes in leaf elongation rate under fluctuating evaporative demand and soil water status. [PDF]
, 2014 Plants are constantly facing rapid changes in evaporative demand and soil water content, which affect their water status and growth. In apparent contradiction with a hydraulic hypothesis, leaf elongation rate (LER) declined in the morning and recovered ...

Morphogenesis in pastures with Tanzania grass fertilized with nitrogen doses under a grazing system
Acta Scientiarum: Animal Sciences, 2015 The morphogenetic and structural characteristics, coupled to forage production of Tanzania grass with nitrogen (N) doses during the seasons of the year, at intermittent grazing, were analyzed.

Carbohydrate Metabolism in Leaf Meristems of Tall Fescue [PDF]
Plant Physiology, 1984 The physiological bases for genetic differences in leaf growth rates were examined in two genotypes of tall fescue (Festuca arundinacea Schreb.) selected for a 50% difference in leaf elongation rate. Genotypes had similar dark respiration rates and concentrations of carbohydrate fractions in the leaf meristem and in each daily growth segment above the ...

Modeling of Shoot Elongation and Leaf Appearance in Potted Mulberry
Plant Production Science, 2000 To predict mulberry growth, modeling of shoot elongation and leaf appearance of potted mulberries was attempted. Potted mulberries were grown in temperature-controlled phytotrons. Changes in the rates of mulberry shoot elongation and leaf appearance, and
