“…The development of succulence in response to salinity is a common observation in dicotyledonous halophytes (Flowers, Hajibagheri & Clipson, 1986). Such an increase in the water content of a plant might mitigate against excessive ion concentrations.…”

SUMMARYAttempts to enhance the salt-tolerance of the cultivated tomato using the tolerance of related wild species of Lycopersicon Mill, have been unsuccessful commercially. An alternative approach is to attempt to accumulate physiological characters that contribute to tolerance within a genotype. We have investigated the relationships between tolerance and certain physiological characteristics in accessions of L. esculentum Mill., L. cheesmanii) Mill, and L. pimpinellifolium Mill, with this aim in view.At a salinity equivalent to 40 % of that in an artificial seawater, the growth of young plants was ranked both in absolute terms (fresh weight, dry weight or the growth in area of a leaf that developed during the salt treatment) and relative to growth in a salinity 2 % of that of seawater. In absolute terms, two cultivars of L. esculentum ('Moneymaker' and 'Edkawy') performed about as well as L. pimpinellifolium and better than L. pennellii and L. cheesmanit : L. peruvtanum showed the poorest tolerance. In relative terms, L. pimpinellifolium remained the most tolerant of the species, and L. peruvianum the most sensitive, L, cheesmanii was little more tolerant than L. peruvianum.The five species differed in their succulence and the Na: K ratio in leaves that developed during the treatment with salinity. Succulence was higher at low salinity in L. pennellii and L, cheesmanii than in the other species, but increased less on salinization, L. pimpinellifolium showed the greatest increase in succulence on salinization, a consequence of its low water content in 2 % seawater. Sodium concentrations increased dramatically in all five species on salinization: L. pimpinellifolium had the highest and L. esculentum the lowest values. L. peruvianum was notable for maintaining a Na: K ratio of less than 3 throughout the period of the experiment.

The authors regret that elements of Appendix 1 were incorrect in the original publication. The correct version of Appendix 1 is given below. Appendix 1. Summary of plant traits Summary of plant traits included in the handbookThe range of values corresponds to those generally reported for field-grown plants. Ranges of values are based on the literature and the authors' datasets and do not always necessarily correspond to the widest ranges that exist in nature or are theoretically possible. Recommended sample size indicates the minimum and preferred number of individuals to be sampled, so as to obtain an appropriate indication of the values for the trait of interest; when only one value is given, it corresponds to the number of individuals ( = replicates); when two values are given, the first one corresponds to the number of individuals and the second one to the number of organs to be measured per individual. Note that one replicate can be compounded from several individuals (for smaller species), whereas one individual cannot be used for different replicates. The expected coefficient of variation (CV) range gives the 20th and the 80th percentile of the CV ( = s.d. scaled to the mean) as observed in several datasets obtained for a range of field plants for different biomes. Numbering of plant traits corresponds with the numbering of the chapters in the handbook Abstract. Plant functional traits are the features (morphological, physiological, phenological) that represent ecological strategies and determine how plants respond to environmental factors, affect other trophic levels and influence ecosystem properties. Variation in plant functional traits, and trait syndromes, has proven useful for tackling many important ecological questions at a range of scales, giving rise to a demand for standardised ways to measure ecologically meaningful plant traits. This line of research has been among the most fruitful avenues for understanding ecological and evolutionary patterns and processes. It also has the potential both to build a predictive set of local, regional and global relationships between plants and environment and to quantify a wide range of natural and human-driven processes, including changes in biodiversity, the impacts of species invasions, alterations in biogeochemical processes and vegetation-atmosphere interactions. The importance of these topics dictates the urgent need for more and better data, and increases the value of standardised protocols for quantifying trait variation of different species, in particular for traits with power to predict plant-and ecosystemlevel processes, and for traits that can be measured relatively easily. Updated and expanded from the widely used previous version, this handbook retains the focus on clearly presented, widely applicable, step-by-step recipes, with a minimum of text on theory, and not only includes updated methods for the traits previously covered, but also introduces many new protocols for further traits. This new handbook has a better balance between whole-plant ...

“…It minimizes the effects of drought caused by salt (Flowers, 1986), temperature (Kluge & Ting, 1978) and water (Fahn & Cutler, 1992) stresses. As transpiration is reduced through a smaller leaf area (Smith, 1978;Hopkins, 1995) and a larger volume (Gates 1968;Kluge & Ting, 1978), both structural components should be also accounted for in succulence measurements, which can be done through the formula proposed here.…”
