Research interests

Dr Stewart's expertise is in the area of physiology and production of vegetable crops. The emphasis in her laboratory is on plant response to stress conditions and/or changes in microclimate. Current projects include: 1) modelling melon growth and development; 2) effects of the environment on changes in the spectral analysis of plastic mulches; 3) the use of thermal tubes to alter the radiation balance inside mini-tunnels; and 4) the effect of optical properties of mulch on aphid populations in pepper.
