J. Vanarendonk ; H. Poorter | 1994To arrive at a better understanding of variation in specific leaf mass (SLM, leaf weight per unit leaf area), we investigated the chemical composition and anatomical structure of the leaves of 14 grass species varying in potential relative growt[...]article/chapitre/communication
V. Gutschick ; L. Kay | 1995Young sunflower plants (Helianthus annuus L.) under stress of low nitrate or phosphate availability exhibited increases in root:shoot ratio and in kinetic parameters for uptake. They showed no significant changes in photosynthetic utilization of[...]article/chapitre/communication
F. Wikstrom ; G. Agren | 1995A series of experiments with cabbage and lettuce, where nitrogen supply is interrupted at a given time and the future development of plant mass and of nitrogen concentration are observed, is re-analysed. Using the nitrogen productivity theory, i[...]article/chapitre/communication
J. Palumbo ; N. Toscano ; M. Blua ; H. Yoshida | 2000A 3-yr project was initiated in 1993 to examine the effects of insecticides and sustained whitefly, Bemisia argentifolii Bellows & Perring [aka. B. tabaci Gennadius (Strain B)], feeding on alfalfa plant growth and vigor in greenhouse cage studie[...]article/chapitre/communication
K. Ishag ; M. Dennett | 1998The expolinear equation for crop growth (Goudriaan and Monteith Annuals of Botany 66: 695-701, 1990) was fitted to measurements of above ground dry weight made on two cultivars of each of three species, faba bean (Vicia faba L.), peas (Pisum sat[...]article/chapitre/communication
M. Dennett ; K. Ishag | 1998The expolinear equation for crop growth (Goudriaan and Monteith, Annals of Botany 66: 695-701, 1990; Goudriaan, 1994. In: Monteith JL, Scott RK, Unsworth MH, eds. Resource capture by clops. Nottingham: Nottingham University Press, 99-110) has th[...]article/chapitre/communication
A mathematical model of carbon accumulation by growing fruit is presented. The model implicitly incorporates the concepts of sink activity and sink size but avoids the need to stipulate sink strength. In addition to sink activity and size, carbo[...]article/chapitre/communication
