Morphological Developments of Orchis purpurea Huds. Salep Orchids

Abstract

Abstract This article aims to monitor the development of Orchis purpurea Huds., salep orchids, of different sizes over a period of two years, and to investigate the relationship between the parameters studied. In the first step, the measurements taken at the time of planting and harvesting of tubers divided into eight different groups according to their size were subjected to variance and Duncan's test. In the second step, the relationship between the parameters was investigated by ignoring seedling groups. The relationship between the two variables was determined by correlation analysis. The significance of the relationships between planting and harvest data sets, and variable contributions were determined by canonical correlation analysis. Finally, leaf area prediction modeling was performed by applying multiple regression analysis. In variance analysis all parameters were significant. The canonical correlation between the first pair of canonical variables was 0.988 (p<0.01). The data obtained from the tubers made the greatest contribution to the explanatory power of the canonical variables. The leaf area model was formulized as LA (mm2) = -1237.0204 + 57.7912 × LW + 16.6211 × LL where LA is leaf area, LW is leaf width, LL is leaf length and a, b, and c are coefficients.
