Effect of Molybdenum Content on Physiological Quality of Bean Seeds: cultivars Novo Jalo and Meia Noite This work evaluated the effect of molybdenum content on the physiological quality of bean seeds, cultivars Novo Jalo and Meia Noite. The experiment was carried out at the Seed Laboratory /UFV, Vicosa-MG, in may-junho/2003. Six Mo contents were tested in seeds of the two cultivars (Novo Jalo: 0.072, 0.74, 1.56, 2.554, 3.892 and 6.767 μg of Mo, and Meia Noite: 0.097, 0.364, 0.761, 1.601, 2.645 and 3.158 μg of Mo), in different assays, complemented with germination and vigor tests, in a complete randomized design, with four repetitions. The effect of Mo content on the seed physiological quality was confirmed, with contents of 3.1 and 2.2 μg seed-1 the values giving maximum physiological quality for cvs. Novo Jalo and Meia Noite, respectively. Optimum Mo dose for production of bean seeds with high physiological quality is 600 and 1200 g ha-1, for the cvs. Meia Noite and Novo Jalo, respectively.
