“…These damaging membrane effects may possibly induce the increase of the injury index partly. These results are in a good agreement with the result of other studies which shows that low temperature and water stress had usually been considered as the major causes of increased cell membrane permeability, relative conductivity and injury index of plant tissue (Blum, 1983;Gadallah, 1995;Zhao et al, 2000;Guo et al, 2006;Wen et al, 2008;Sun and Jin, 2007).…”

Water deficiency and low temperature are two important ecological factors which affect the distribution and cultivation of oil palm. To find out how oil palm adapts to the environmental conditions, the dynamics of a series of important physiological components derived from the leaves of potted oil palm seedlings under drought stress (DS) (water with holding) and low temperature stress (LTS) (10°C) were studied. The results showed that low temperature and water stress inhibited the growth of oil palm seedlings. The relative conductivity, injury index, malondialdehyde (MDA) and proline content in the leaves increased to different degrees with the extension of low temperature and drought stress. Superoxide dismutase (SOD) and peroxidase (POD) activities increased and then decreased gradually with the duration of treatment time. The variations of the earlier mentioned parameters except proline content under low temperature stress were greater than that under drought stress. Thus, oil palm possibly showed different response mechanisms under low temperature and drought stress by mediations of these substances, in order to increase plant defense capability. These data provided the information that was utilized to initiate the breeding programme used to improve drought and cold tolerance in oil palm.

“…The physiological parameters such as Relative leaf water content (RLWC; Gadallah, 1995), Leaf proline accumulation (Yancey et al, 1982) and Chlorophyll stability index (CSI; El-Sharkawi and Salama, 1977) are some sensitive physiological indicators used to study the response of plants under moisture stress condition.…”

“…A possible clue of cross-talk also exists with the fact that ABA and Pro sprayed together in stressed cotton plants significantly enhanced chlorophyll content, chlorophyll stability index, leaf relative water content, and dry matter accumulation at low water potential (Gadallah, 1995). Induction of Pro synthesis by ABA and salt stress correlates with a striking activation of P5CS1 expression, whereas P5CS2 is weakly stimulated.…”

Proline (Pro) accumulation is a common response of several plant species to combat abiotic stresses. Under stress conditions, Pro acts as an excellent compatible solute in the plant system, participating in the alleviation of stress sensitivity. Though the metabolic pathways associated with Pro are well studied, parts of its regulatory cascades are still not properly known. It has also been conjectured that epigenetic modifications regulate Pro metabolism during abiotic stress. Apart from Pro, the plant abiotic stress responses are essentially mediated by multiple effectors. Hence, proper analysis of the cross-talks of Pro with the other components of the abiotic stress response has turned out to be mandatory in order to design multistress-tolerant transgenic lines. Highlighting the relation between Pro and seed germination is also essential to understand the notion behind plant susceptibility and survival during stress. Generally, Pro has a universal mechanism to generate abiotic stress tolerance through stabilization of structural components, enzyme structures, and regulation of osmotic adjustments. The success achieved through recent transgenic approaches leading to more accumulation of Pro in the sink has also been focused on in the present review.
