Water Relations in Tissue-cultured Soybean Plants

Acclimatization of tissue-cultured plants

A substantial number of micropropagated plants do not survive transfer from in vitro conditions to greenhouse or field environment. The greenhouse and field have substantially lower relative humidity, higher light level and septic environment that are stressful to micropropagated plants compared to in vitro conditions. The benefit of any micropropagation system can, however, only be fully reali...

Apparent photosynthesis of soybean plants as affected by changes in leaf water potential under field conditions

Photosynthetic and Water Relations in Orange Plants with Cvc

Plants with citrus variegated chlorosis (CVC), a disease caused by the xylem-limited bacteria Xylella fastidiosa, have leaves with water deficiency symptoms and are associated with decreases on the net photosynthesis and transpiration rates. Using healthy and CVC-affected ‘Pêra’ sweet orange plants on ‘Rangpur’ lime rootstock, the leaf gas exchange variables were measured with an open-gas porta...

ought stress in plants: A review on water relations

term stress is used, most often subjectively, with various meanings, the physiological inition, and appropriate term as responses in different situations. The flexibility of normal tabolism allows the development of responses to environmental changes which fluctuate ularly and predictable over daily and seasonal cycles. Thus every deviation of a factor its optimum does not necessarily result in...

Stomatal behavior and water relations of waterlogged tomato plants.

The effects of waterlogging the soil on leaf water potential, leaf epidermal conductance, transpiration, root conductance to water flow, and petiole epinasty have been examined in the tomato (Lycopersicon esculentum Mill.). Stomatal conductance and transpiration are reduced by 30% to 40% after approximately 24 hours of soil flooding. This is not due to a transient water deficit, as leaf water p...
