Evaluation of Salt Tolerance in Lettuce Landraces from Korea
Image
Fig. 1. Dendrogram of the relative tolerance to salinity of 32 lettuce landraces from Korea (A : 100mM salt, B : 200mM salt). On the left side of figure (A), the cluster analysis allowed for grouping the genotypes into four groups: very tolerant (Group 1), tolerant (Group 2), intermediate (Group 3) and sensitive (Group 4). On the right side of figure (B), 32 lettuce landraces from Korea were separated into six groups: very tolerant (Group 1), tolerant (Group 2), upper-intermediate (Group 3), lower-intermediate (Group 4), sensitive (Group 5) and very sensitive (Group 6).
Evaluation of Salt Tolerance in Lettuce Landraces from Korea

Effect of different salt concentration on electrolyte leakage, chlorophyll index and fresh weight in lettuce landraces from Korea.

Effect of different salt concentration on dry weight, number of leaves and leaf area in lettuce landraces from Korea.

Changes of photosynthetic and growth response according to groups segregated by cluster analysis under different salt concentration.

Percent increase or reduction was calculated based on value observed in plants grown under control condition.

Means followed by different letters in the same column are significantly different (LSD, P≤0.05).
