“…It affects a range of physiological and biochemical activities in plant system depending on the severity and duration of the cold stress (Salaj 1999). Cold temperatures often increase membrane permeability and disrupt membrane integrity (Campos et al 2003), causing electrolytes from stressed cells to leak into the surrounding apoplast.…”

Abscisic acid (ABA) has a key role in some plant species under low-temperature stress (LTS). In this study the effects of ABA at four concentrations (0, 50, 100 and 200 lL) on electrolyte leakage (EL), visual damage index, soluble carbohydrate, proline, total phenolic compound and relative water content (RWC) of leaves of 'Sultana' grapevines were studied under LTS (0, 4 and -4°C). Moreover, to further elucidate the efficiency of foliar ABA on freezing tolerance, some relevant morphophysiological changes were evaluated at three sampling dates: September, October and November. The increase in cane and leaf EL and the visible symptoms of leaf damage caused by LTS were minimized by the application of ABA. Moreover, in ABA-treated vines, specifically at 200 lM, the contents of soluble carbohydrate, proline and total phenolic increased and the RWC decreased. These alterations in ABA-induced metabolism alleviated the deleterious effects of LTS on 'Sultana' grapevine. Freezing tolerance of ABA-treated vines improved within each sampling date in autumn. Foliar application of ABA at 200 lM decreased LT50 in September, October and November by -2.6, -3.6 and -3.9°C, respectively, as compared to those of control vines. This study also demonstrated that ABA was effective in shoot growth inhibition, leaf abscission and periderm development, indicating that ABA treatments advanced cold acclimation in grapevines. Increased fall freezing tolerance induced by foliar ABA application may be beneficial in nurseries, new established vineyards and for late-bearing cultivars in regions with fall frost events.

The ultrastructure and dimensions of chloroplasts in leaf mesophyll cells were quantitatively examined in three parental inbred lines of maize (Zea mays L.) and their four hybrids subjected to two types of four-week low-temperature (LT) treatment: the abrupt onset of chilling temperatures ("severe chilling", SC) and the gradual, more moderate one ("moderate chilling", MC). The relationship between the response of individual genotypes to one or the other type of chilling was analyzed as well as the possibility to predict the behaviour of chloroplasts in hybrids from that of their parents. Although selected parameters of chloroplast ultrastructure (e.g. volume densities of granal and intergranal thylakoids, plastoglobuli, and peripheral reticulum) and dimensions changed due to the exposure of maize plants to LT, no general pattern of such changes was found for this species due to the observed intraspecific variability. The response of some genotype to SC could not be predicted from its behaviour under MC (and vice versa) and no clear rules could be applied for the inheritance of chloroplast response to chilling in the general sense. Thus, great caution should be always taken when interpreting the results of studies aimed at the dissection of chloroplast ultrastructure as affected by LT, particularly in case such studies are made with one genotype or under one type of chilling only.
