PHYSIOLOGICAL CHARACTERISTICS OF NARBON VETCH (VICIA NORBONENSIS L.) PLANTS
MetadataShow full item record
Physiological characteristics should be defined for better assessment of plant growth and development. Such characteristics play a significant role in finding out optimum intervention time. Vetch is commonly used in animal feeding. Therefore, it is quite significant to work on vetch yield and quality. Vetch constitutes about 10% of feed crop production of Turkey. Therefore, vetch cultivars and lines were used and physiological characteristics of Narbon vetch (Vicia norbonensis L.) plants were determined. Leaf area index, leaf area ratio, relative leaf growth ratio, relative growth ratio, net assimilation ratio and plant growth ratio were determined. Present findings revealed that leaf area index was a significant parameter for growth and development of all genotypes. Leaf area ratio and net assimilation ratio were also identified as the other effective physiological factors. Leaf growth ratio did not have significant effects. Correlations of dry matter yield with physiological characteristics revealed that leaf area index was significant in all parameters and it was followed by leaf growth ratio. Present findings revealed that Narbon vetch genotypes had significant differences in their physiological characteristics.
