2.1.2Growing temperature of crops inside the greenhouse The selection ofPCMsis mainly determined by the suitable temperature range for growing crops in the greenhouse. There are three main different types of crops in greenhouses: typical thermophilic crops (recommended heating/cooling set point: 20 °...
For winter crops, the effect of predicted prolonged summer drought periods and heat weaves for the next decades may be smoothed or prevented due to the faster development that will allow escaping these and then avoiding reduction in final yields. In contrast, crops, whose growing cycle takes ...
To assess the role of photoinhibition in cold acclimated herbaceous plants in their natural environment, we studied the effects of night frost and of high solar irradiation on cool days on photosynthesis of spinach ( Spinacia oleracea L. growing in the field during winter. Fluorescence emission (...
An evaluation of direct and indirect mechanisms for the "sink-regulation" of photosynthesis in spinach: Changes in gas exchange, carbohydrates, metabolites... Mature source leaves of spinach (Spinacia oleracea L.) plants growing hydroponically in a 9 h light (350 碌mol photons路m-2 路 s-1)...
a treatment of one week of low temperature stress in spinach plants increased the leaf concentrations of quality compounds like sugars,ascorbic acidand Fe2+, at the same time reduced the leaf concentrations of compounds considered harmful for human health like NO3−and oxalic acid (Hidaka et al...

A higher recovery under dark and cold conditions may be a great advantage for the Antarctic ecotype which has a very short growing season. Especially the increased net photosynthesis observed upon cold-acclimation may represent the difference between gaining just enough carbon for vegetative growth or...
but there was no significant change in the control group at room temperature for 3 days. The single plant weight after treatment also showed different changes (Fig.1a). The single plant weight after high temperature and low temperature treatment was significantly decreased by 18.28 and 6.50%, res...
divided by that at low-growth temperature was close to 1.0) than deciduous woody plants and annual herbaceous plants, indicating that photosynthetic acclimation would be particularly important in perennial, long-lived species that would experience a rise in growing season temperatures over their life...
Previous studies have reported that both ecotypes have similar optimal temperature for photosynthesis ranging from 17 to 24°C depending on growing conditions [30, 37] However, low temperature exposure (cold acclimation) improves the Antarctic ecotype responses to photoinhibitory conditions, such as a...
