Abstract/Contents:Presents a study analyzing "free sugars (glucose, fructose and sucrose) and fructans in tall fescue organs (leaf blade, shoot and root) from adult plants subjected to cold (4┬░C [Celsius]), darkness, drought and salinity for prolonged time" to determine the relationship between abiotic stresses and fructan metabolism in tall fescue (Festuca arundinacea Schreb.). Details methods and materials used in the study, stating that "pots were maintained in a greenhouse for two months and plants were mowed every week at 7 cm [centimeters]. After that plants were stressed: control, salinity (100 mM NaCL [sodium chloride] solution) and drought (no water) samples were maintained in a growing chamber at 28┬░ with a 12 h [hour] photoperiod...Darkness treated-plants were maintained in the same growing chamber with a black cover film, while cold treatment was imposed in a controlled incubator at 4┬░C with a 12 h photoperiod." Concludes that "with the exception of salinity, sugar modulation appear to be an adaptive strategy of tall fescue plants in response to abiotic stresses....tall fescue plants operate different carbohydrates levels modulation depending on the abiotic stresses imposed. In fact an increase of free sugars represent the response to cold conditions while drought induces a strong accumulation of fructans. On the contrary darkness induces a strong fructan depolymerisation."
