“…Exogenous GB application also significantly affected osmolytes accumulation in crops under DS (Zhang and Li 2004;Tables 3, 4, 5, 6). With decreasing soil moisture, foliar spray of GB significantly increased leaf concentration of free proline in wheat (Sun et al 2001), endogenous GB in soybean [Glycine max (L.) Merr] (Agboma et al 1997) and soluble sugar in apricot (P. armeniaca L.) (Liu et al 2004).…”

We investigated the effects of exogenous glycinebetaine (GB) and drought stress (DS) on grain yield (GY) and production of dry matter (DM) and osmolytes in two maize (Zea mays L.) cultivars i.e. Shaandan 9 (S 9 ) and Shaandan 911 (S 911 ) during the entire growing period. Drought stress substantially reduced DM and GY but increased free proline, endogenous GB, soluble sugar and K ? concentrations in leaves of both cultivars. The DM production, GY, drought index (DI) and concentrations of these osmolytes were greater for S 9 than those for S 911 under DS. The significant differences in these parameters suggested that S 9 was more drought-tolerant as compared to S 911 . Additionally, foliar application of GB increased the concentrations of all osmolytes measured, DM and GY of both cultivars under DS. These positive responses of exogenous GB spray were more pronounced in S 911 as compared to those in S 9 . Further correlation analysis involving a number of parameters indicated that maize production was tighterly correlated with accumulation of the osmolytes measured during DS rather than wellwatered controls. Accordingly, this study demonstrated the notion of an anti-drought role of exogenous GB by osmoregulation under DS, particularly in this drought sensitive cultivar. Thus, exogenous GB application might be firstly used with drought sensitive species/cultivars when exposed to DS.

“…The exogenous application of glycine betaine (20 ppm) also recorded significantly increase in dry weight of plant over unirrigated control while it remained significantly lower than irrigated control. Glycine betaine may act on an antitranspirant which allowed the plant to access water for a longer period and facilitates more photosynthesis as reported by Agboma et al (1997) in soybean above ground dry matter increment following foliar application of glycine betaine. All other exogenous applications were not promising.…”

“…Glycine betaine is a quaternary ammonium compound accumulated by many species (Wyn Jones and Storey, 1981). Results from recent field and/or greenhouse experiments have shown promising effect on drought tolerance and crop growth through exogenous glycine betaine in spring cereals and summer turnip rape (Makale et al1996), soybean (Agboma et al, 1997), tomato (Makela et al, 1998), cotton (Gorham and Jokinen, 1998) and kidney bean (Lopez et al, 2002). Other compound, the polymines also accumulated during stress and determined by the plant species affected and the nature of stress (Rabe, 1990).…”

“…Varieties V4 and V5 also produced considerable shoot dry biomass while maximum shoot dry weight was found in V9 and V10. Root and shoot characteristics of cotton genotypes were measured by [28] to sort out drought tolerant ones indicating that the varieties that produced more root and shoot dry weight under water stress conditions have genetic potential to tolerate water stress and it was found that these two traits enhance drought tolerance [29]. Some researchers [30] also worked on tomato under normal and water stress conditions and found no significant effect of application of 1/3 (T1) and 2/3 (T2) of full irrigation at seedling stage (as stage-I) on its water uptake efficiency, yield and tomato quality.…”

Tomato belongs to family solanaceae and is a source of many antioxidants important for human health like B-carotene, lycopene, ascorbic acid etc. Its production is challenged by many abiotic stresses including water stress on the top. Genetic potential of ten tomato genotypes was evaluated under normal and water stress conditions in Department of Plant Breeding & Genetics, Ghazi University, D. G. Khan. Nursery of these genotypes was raised in plastic pots. Seedlings were transplanted in the field under completely randomized block design (RCBD) after three to four weeks of germination. Data on various seedling traits were recorded. Highly significant results were found for analysis of variance in many plant traits. Correlation analysis indicated vegetative traits have mostly positive and significant association with each other like plant height and number of leaves have positive correlation with number of branches. GIACIER and DONA among all genotypes of tomato having best performance under normal and water stress conditions for plant traits like root length, fresh shoot weight, fresh root weigh, dry root weight, number of branches and plant height. So, these varieties are recommended for further breeding program and can be grown under water stress conditions for high yield.
