Carbon isotope discrimination (D) and ash content (m a ) have been proposed as indirect selection criteria for grain yield in wheat. The associations between D, m a and grain yield were found, however, to depend highly on the environmental conditions, the organ sampled and the time of sampling. In this study, carried out in the warm conditions of the Peninsular Zone of India, the relationship between D, m a and yield was studied in 30 bread and durum wheat cultivars under residual soil moisture stress (RSMS), post-anthesis water stress (PAWS) and well-watered (WW) conditions. Both D and m a were analysed in young seedlings (four-leaf stage), leaves at anthesis and grain at maturity. Ash content was also evaluated in leaves at booting stage and maturity. Grain D was lower under PAWS and RSMS than under WW, while seedling and leaf D did not significantly differ among water regimes. Grain yield was positively correlated to grain D under PAWS and negatively correlated to grain m a under RSMS. A significant positive correlation was noted under RSMS and WW treatments between m a L m and grain yield. Ash content in leaf at maturity consequently appears to be a useful indirect selection criterion in environments where D does not show any correlation with yield. The results highlight the potential of D and m a as indirect selection criteria for wheat yield in the conditions of the Peninsular Zone of India.

“…The other three parameters i.e., internal CO 2 concentration, stomatal conductance and transpiration rate did not show any significant correlation with the leaf yield except that of water use efficiency, which had a very strong positive correlation with the leaf yield. Similar type of strong correlation between WUE and yield was observed in barley (Febrero et al, 1994). Likewise, photosynthetic rate was positively correlated with the shoot dry weight of cotton (Brugnoli and Lauteri, 1990).…”

Information on interrelationships among traits is important for varietal development. Under stress conditions the magnitude of character association is known to change significantly. In mulberry such information on such aspects is lacking. Hence, the interrelationships of leaf yield and its component morphological, physiological and biochemical traits were investigated under four different salinity conditions using 11 genotypes. Correlation coefficient between leaf yield and its component traits was found changing significantly under different salinity stresses. Under normal condition leaf yield was found significantly and positively correlated with leaf size, root length, shoot length, protein content, and water use efficiency. However, under severe salinity imposed by 1.00% NaCl, significant correlation was observed with plant height, leaf size, shoot weight, root weight, root length, protein, nitrogen reductase (NRase) activity and water use efficiency (WUE) of the plant. Similarly, relationship of plant height with other traits also changed with increasing salinity. These changes in the interrelationships among the traits point to the need of different selection strategy for breeding varieties under normal and abiotic stress conditions.

“…To reduce the high cost of Δ analysis, many previous studies have suggested that foliar ash content and K concentration could be used as cheap, putative surrogates of Δ (Febrero et al 1994, Merah et al 2001a, Misra et al 2006, Tsialtas et al 2002. In this study, the significantly positive relationships between Δ and ash content in both P. euphratica and T. ramosissima were revealed.…”

Grain in bread wheat and barley (Masle et al 1992, Febrero et al 1994 and in C. korshinskii (Zhao et al 2007) as well as seed cotton (Tsialtas et al 2008) were also found in the same negative correlation. Those show that a passive transport of K nutrients through the transpiration stream is not the only factor that determines mineral content in P. euphratica, and that K plays an important role in regulating stomatal functions as well as showing that K is an easily lapsed nutrient element.…”

Carbon isotope discrimination (Δ) has been proposed as an indirect estimation criterion for water use efficiency in C 3 plants. Because of the higher cost for Δ analysis, ash content or K concentration has been proposed as an alternative criterion for Δ in many species. In five typical habitats of the extreme arid Ejina desert oasis in northwest of China, the seasonal variations of foliar Δ, ash content, and potassium (K) concentration were researched in two constructive desert riparian plants (Populus euphratica Olivier, Tamarix ramosissima Ledeb). The correlations of foliar Δ with ash content and K concentration in both species were also examined to evaluate the feasibility of the foliar ash content and K concentration as surrogates of Δ in P. euphratica and T. ramosissima. Results showed that there were significant effects of plant species, habitats and growth season on foliar Δ, ash content, and K concentration. Foliar Δ and K concentration in P. euphratica were significantly higher than those in T. ramosissima, whereas, the ash content was reverse. Among habitats, the trends of Δ signatures in both P. euphratica and T. ramosissima were similar, Δ values and ash content in both species were the lowest in the dune. Both in the Gobi and dune sites, K concentration in P. euphratica and T. ramosissima was different. In the whole growth period, foliar Δ values and ash content in both species were gradually increased, but K concentration was decreased. Ash content was significantly and positively related to Δ in both P. euphratica and T. ramosissima. However, significantly negative correlations between foliar Δ and K concentration as well as between ash content and K in P. euphratica were found. In T. ramosissima, the relationship was positive but very weak.
