“…Relative water content is a good and simple index of plant water status. Low temperature stress indirectly induces water stress (Eze et al, 1983); hence, the level of water stress induced by chilling can be measured by RWC. Chilling treatment decreased the RWC of S. guianensis , indicating that water stress occurred at low temperature.…”

Stylosanthes guianensis (Aublet) Sw. is an important pasture legume in tropical and subtropical countries. Chilling injury of S. guianensis is a serious problem in subtropical cultivated areas. An experiment was conducted under controlled conditions to study the effect of abscisic acid (ABA) on S. guianensis and its relation to antioxidant systems under chilling stress. Stylosanthes guianensis seedlings were sprayed with 10 mg L−1 ABA or water. One day later, the plants were transferred to a 10°C growth chamber and grown for 7 d with a 12‐h photoperiod at 160 μmol m−2 s−1 photosynthetic photon flux density. The chilling treated plants were then rewarmed to 28°C for 2 d. During the 9‐d treatment, a series of enzyme activities, relative water content (RWC), and electrolyte leakage were measured on sampled leaflets. The results showed that chilling increased electrolyte leakage of both water‐ and ABA‐treated plants, while RWC decreased under chilling conditions. ABA‐treated plants had lower electrolyte leakage and higher RWC than those of water‐treated plants. Activities of ascorbate peroxidase (APX) and catalase (CAT) and contents of reduced glutathione (GSH) and ascorbic acid (AsA) were transiently enhanced by ABA treatment before the plants were subject to chilling. ABA‐treated S. guianensis retained higher levels of superoxide dismutase (SOD), APX, GSH, and AsA than water‐treated ones under chilling conditions. The results suggested that ABA‐increased chilling resistance in S. guianensis is partially associated with enhanced scavenging systems.

“…Water imbalance is frequently accompanied by chilling stress Kabaki & Tajima 1981;Me William et al 1982;Wright & Simon 1973). The increase of ABA levels has been suggested to be caused by chilling-induced water stress (Eze, Dumbroff & Thompson 1982;Lalk & Dorffling 1985;Vemieri etal. 1991).…”

Changes of ABA levels in chilled rice {Oryza sativa L.) seedlings of two varieties were determined. On exposure to chilling, ABA concentration rapidly increased in the chilling-tolerant cultivar (cv. Tainung 67, TNG.67) but not in the chilling-sensitive cultivar (cv. Taichung Native 1, TN.l). Both detached shoots and roots of TNG.67 seedlings showed a significant ABA increase after exposure to chilling. TN.l seedlings could not accumulate ABA under low temperature but well-watered status. Exogenous application of the ABA biosynthetic inhibitor, fluridone, reduced ABA accumulation, as well as survival ratio of chilled TNG.67 seedlings. Electrolyte leakage and leaf conductance were also increased by the inhibitor and the effects could be reversed by exogenously applied ABA. ABA concentrations in xylem sap of TNG.67 seedlings increased within 4 h after chilling, and this was temporally coincident with the reduction of leaf conductance. The roles of endogenous ABA in the tolerance of rice seedlings to chilling on a whole plant basis are discussed and suggested.

“…ABA is believed to play a role in plant tolerance to extreme environmental conditions (Salisbury and Marinos, 1985;Zeevaart and Creelman, 1988). Endogenous ABA accumulation in response to environmental stress has been shown in many plant species Eze et al, 1983;Skriver and Mundy, 1990;Zeevaart and Creelman, 1988). Many studies have demonstrated ABA accumulation during cold acclimation of plants and cold tolerance induction by exogenous ABA application (Bomman and Jansson, 1980;Chen and Gusta, 1983;Reaney et al, 1989).…”

Heat tolerance and endogenous ABA levels in leaves and cultured grape cells (Vitis spp., cultivars Venus and Veeblanc) were evaluated during beat acclimation. Plants and cultured cells were acclimated at 38 and 36C, respectively. Heat tolerance increased rapidly after exposing plants or cells to acclimation temperatures, reaching a maximum after 10 to 16 hours and 10 to 12 hours for leaves and cultured cells, respectively. Free and bound ABA levels increased sharply during the first hour of heat acclimation, before leaves and cultured cells reached their maximum beat tolerance. The increase in ABA during heat acclimation was 2- to 3-fold that of the nonacclimated control, and the time of the ABA accumulation peak in tissue roughly corresponded to the maximum heat tolerance in leaves and cultured cells. Heat tolerance was induced in cultured cells by exogenous ABA application. Heat tolerance increased significantly after 24 hours of ABA application at 7.6 or 9.5 μm. The results suggest that ABA may be a factor in high-temperature acclimation and beat-tolerance induction in grapes. Chemical name used: abscisic acid (ABA).
