This study focuses on the evaluation of the effect of pre-germination seed treatment in Laburnum anagyroides Med. on sapling germination and status during the first growth stages. Seeds were moistened for 24 h with cold water (V1), hot water 90ºC (V2), stratification (V3) and scarification (V4). The best effects on medium germination was with scarification (98% germinated seeds), followed by stratification (87% germination), hot water (76%) and cold water (70%). The effect of the treatments was also in sapling status 37 days after sprouting, the proper age for transplanting. From the perspective of the biometric and physiological parameters, were studied collar diameter (D), sapling height (H), root number (Rn), root length (Rl), leaf number (Ln) and leaf area (LA), the best effects were generated by scarification, followed by stratification, with statistically ensured differences. Cluster analysis of results facilitated the grouping of experimental variants based on Euclidian distances into two clusters with statistic safety (Cophenetic coefficient = 0.887). |
