“…Proline accumulation has been noted in most winter cereal species when they are subjected to abiotic stresses : accumulation of proline under water stress has been described in barley (Singh et al ., 1973) as well as in bread (Triticum aestivum) and durum wheat (Monneveux & Nemmar, 1986). The physiological significance of water stress induced accumulation of proline is not clear, and the underlying mechanisms involved in this accumulation are still poorly understood.…”

The possibility of using proline accumulation and fluorescence inhibition as predictive tests for drought tolerance in durum wheat has been investigated . The drought susceptibility of 25 genotypes was evaluated by comparing yields and yield components in irrigated and non irrigated conditions in the field . A drought susceptibility index (DSI) was calculated based on yields from irrigated and dry treatments and compared with the results obtained using the two physiological criteria . Proline accumulation and chlorophyll fluorescence inhibition were found to be significantly and negatively correlated with DSI of grain yield, biological yield, and thousand kernel weight, and tiller index . The use of both criteria for breeding durum wheat in Mediterranean dryland is discussed .

SUMMARYChanges in sugar content during water stress and recovery were examined in leaves of two varieties of durum wheat {Triticum durum). The drought-resistant Mohamed Ben Bachir (MBB) from Algeria and the droughtsensitive European variety Capdur differed in the time and type of sugar increase during water stress. Glucose accumulated at a rate closely corresponding with decreasing water potential but more rapidly and to a higher concentration in MBB than in Capdur. Sucrose content correlated less well than that of monosaccharides with changes in water potential. Glucose and, to a lesser extent, fructose appeared to play an important role during water stress and to be more sensitive indicators of the degree of stress and of potential tolerance than proline which increased later and to the same extent in both varieties. After rewatering, the amounts of accumulated solutes in leaves of both types fell quickly to normal, coincident with relatively rapid growth.

The changes in the levels of proline, sugar and soluble protein during leaf rolling and its relationship to osmotic adjustment were studied in laboratory conditions. Upon irrigation of plants which have rolled leaves, many sugar crystals occurred on the abaxial surface of the leaves in Ctenanthe setosa (Rosc.) Eichler. The sugar crystals were determined to have sucrose, glucose and fructose. The levels of reducing sugars and proline are higher in rolled leaves while soluble protein levels in rolled leaves are lower than those of unrolled leaves. It was found 1-3, 9-13, 16-21 and 24-28 crystals at degree of leaf rolling 23, 28, 47 and 52 %, respectively. Finally, we found a significant correlation between the crystal number and degree of leaf rolling in Ctenanthe setosa. In addition, soluble sugars are found predominant accumulating solute in the plant and are of major importance as a contributor to osmotic adjustment during leaf rolling.
