The study evaluated the interdependence between foliar parameters and physiological indices in the composed leaves of Robinia pseudoacacia L. The length (L) and width (w) of eight leaflets (Ll1 to Ll8) on the left side (L) and on the right side (R) of the compound leaves petiole were measured. The perimeter (Per), leaf area by scanning (SLA), chlorophyll content (Chl) and carotenoid content (Car) of each leaflet were determined. Correlations of different levels of intensity were identified between parameter and physiological indices, in conditions of statistical safety (p <.05; p <.01; p <.001). The SLA variation in relation to foliar parameters (L, w, Per) was described by linear and polynomial equations in statistical safety conditions (R2 = 0.972 to R2 = 0.998 for leaflets on left side; R2 = 0.913 to R2 = 0.996 for leaflets on right side). The variation of Car in relation to Chl was described by a linear equation in the case of leaflets on left side (R2 = 0.923, p < 0.001) and by a polynomial equation in the case of leaflets on right side (R2 = 0.941, p <0.001). The results also indicated a certain asymmetry at the level of the pair leaflets on the petiole. [ABSTRACT FROM AUTHOR] |
