Seed Water Absorption, Germination, Emergence and Seedling Phenotypic Characterization of the Common Bean Landraces Differing in Seed Size and Color

Common bean (Phaseolus vulgaris L.) is the most widespread legume in Croatia and its production based on landraces of great morphological diversity. Landraces morphologically differ seed coat color size. Because plant emergence crop establishment represent sensitive stage development, aim this study was to determine whether size Croatian common affect water absorption rate, germination, phenotypic characteristics seedlings. In seeds four with different size, ‘Biser’ (white-colored, small-seeded), ‘Bijeli’ large-seeded), ‘Kornja?a’ (dark-colored, small-seeded) ‘Trešnjevac’ large-seeded) were evaluated three experiments: (i) uptake, (ii) germination (iii) seedling characterization. The results show that white-colored have a higher rate release more electrolytes compared dark-colored similar (and weight). smaller germinate faster large seeds. On other hand, landrace took longest time emerge, probably due cell damage occurred during fast initial absorption. Using multispectral imaging, chlorophyll fluorescence imaging stomatal conductance analysis, seedlings large-seeded found contain photosynthetic pigments light contrast, lower transpiration photochemical efficiency (despite possible germination). Results suggest could survive better under unfavorable soil conditions without absorbing water, swelling, or molding than Despite all this, remain popular human diets are often grown small-scale farms.
