The effects of CO2 concentration on the canopy photosynthesis and winter bloom production of the glasshouse rose 'Sonia' (Syn. 'Sweet Promise')


, : The effects of CO2 concentration on the canopy photosynthesis and winter bloom production of the glasshouse rose 'Sonia' (Syn. 'Sweet Promise'). Acta Horticulturae (51): 243-252

Photosynthesis curves at concentrations of 400, 800 and 1200 v.p.m. CO2 were obtained from experimental data by the use of a mathematical model that relates net canopy photosynthesis to light, CO2, respiration, canopy structure and the optical and photosynthetic characteristics of individual leaves. At a light level equivalent to the maximum experienced under glass at the winter solstice in Britain the net rates of CO2 uptake for stands assimilating in air enriched to 800 and 1200 v.p.m.

The physiological function of the GluRdelta subfamily which is one of the glutamate receptor (GluR) channel subunits has not yet been clarified, because no GluR channel activity has been detected in heterologous expression systems. The Lurcher mut...
