Puvirajasinghe, Patrick (Texas A&M University. Libraries, 1986)Three crop moisture stress indices (CMSI1, CMSI2 and CMSI3) are proposed. In computing index 1 and 2, stress is assumed to occur when the actual to potential transpiration ratio (AT/PT) falls below a critical level, while ...

Shaer, Yacoub Adib (Texas A&M University. Libraries, 1985)Three adjacent ventilated mini-greenhouses (MGH) made of clear polyethylene film, transmitting natural solar radiation, were enclosed in a conventional inflated polyethylene greenhouse. In each MGH, an equal number of ...

Davis, Stephen Darrel (Texas A&M University. Libraries, 1974)The objectives of this research were: 1) to determine if leaf age significantly affects leaf resistance to gaseous diffusion in Phaseolus vulgaris at constant light and external CO₂ level, leaf temperature, ambient humidity ...

Kano, Atsushi (Texas A&M University. Libraries, 1985)A deterministic, compartmental growth model of greenhouse tomato plants, written in Pascal computer language, was developed based on a leaf assimilation model and a model of a theory that the photosynthesis rate is controlled ...
-
Maas, Stephan Joseph (Texas A&M University. Libraries, 1985)A model was developed to simulate the growth of individual wheat plants within a field community. Based on hourly observations of irradiance and temperature, one portion of the model (PHOTO) computes the daily photosynthesis, ...

Costa, Sotto Pacheco (Texas A&M University. Libraries, 1985)Two sorghum cultivars, ATx378 x RTx430 [(34), higher stem carbohydrates and slower rate of senescence] and ATx378 x RTx7000 [(37), lower stem carbohydrates and more rapid rate of senescence] were utilized in a study of ...

Johns, Don (Texas A&M University. Libraries, 1980)A controlled environment study of evapotranspiration from St. Augustinegrass turf, Stenotaphrum secundatum (Walt.) Kuntze, showed that, under well-watered conditions, evapotranspiration was influenced to a greater extent ...
-
Ham, Jay Matthew (Texas A&M University. Libraries, 1990)When crops are cultivated in a row configuration, latent heat flux from the soil (LE[s]) and crop canopy (LE[c]) influence the energy and water balance of the crop. Field experiments were conducted in Lubbock, TX to examine ...
-
Baker, John Morgan (Texas A&M University. Libraries, 1987)A growth chamber experiment was conducted to test the hypothesis that an unirrigated plant could survive if its root system overlapped with irrigated plants on either side. A box 1.8 m long, 0.2 m deep, and 0.24 m front ...
-
Vining, Kevin C. (Texas A&M University. Libraries, 1988)Ridge-furrow tillage systems establish heat and moisture fluxes in two dimensions. However, no models had been developed previously which permitted quantitative investigations of temperature fluctuations, redistribution ...
-
Lascano A., Roberto (Texas A&M University. Libraries, 1982)A model of root water uptake is described and was tested experimentally. The model proposes that the local rate of water uptake by the root system of a plant is directly proportional to the difference between the water ...

van Bavel, C. H. M. (Texas Water Resources Institute, 1972-06)This report examines the validity and explores the practical implications of the proposition that CO2 enrichment of the leaf environment enhances plant growth and, simultaneously decreases plant water use. A theoretical ...
