screening methods for aluminum tolerance in alfalfa

A rapid hydroponic screening for aluminium tolerance in

A hydroponic system was developed to screen for Al tolerance in barley (Hordeum vulgate L ) to overcome several problems encountered in previous screening methods Four levels of Al (5 10 20 and 40 μM) in 1 mM CaCl 2 solution at pH 4 5 were used to rank lines for Al-tolerance

4 3 Drought tolerance: Screening methods

In order to identify sources of drought resistance it is necessary to develop screening methods that are simple and reproducible under the target environment conditions Therefore managing drought-screening nurseries requires a careful analysis of likely sources of non-genetic variation among plots replications and repeated experiments and establishing procedures for minimizing these factors

Screening of grape genotypes for aluminum tolerance and

The coefficient for the tolerance to aluminum of each character was used as the index of aluminum tolerance The principal component analysis method was used to combine 13 individual indices into five independent comprehensive indices which could represent 85 341% of the original data on the tolerance of the plants to aluminum

Performance of tetraploid alfalfa genotypes as exposed to aluminum

ing USA cultivars [45] identified an alfalfa genotype with increased tolerance to aluminum and that was later confirmed by [46] using tissue culture approaches In addition [47] and [48] detected genetic variability for tolerance to aluminum in regional alfalfaIt is

A comparative study of screening methods for tolerance to aluminum

information regarding screening of genotypes for aluminum tolerance in pigeonpea is meagre The effects of five levels of aluminum concentrations (0 10 20 30 and 50 g ml -1 Al) on 32 pigeonpea genotypes were studied by four different methods: hydroponic and

Plant improvement for tolerance to aluminum in acid soils

Aluminum tolerance appears to be a complex multigenic trait Selection methodology remains a limiting factor in variety development as all methods have particular drawbacks Molecular markers have been associated with Al tolerance genes or quantitative trait loci in Arabidopsis and in several crops which should facilitate development of additional tolerant varieties
