• Subiect: THE LEVEL OF ANNUAL PRIMARY PRODUCTIVITY OF THE LAYER OF HERBS IN CERTAIN ZONAL FOREST OF SOUTHERN CARPATHIANS AND THE GETIC PLATFORM The article presents the primary production of entire herbaceous layer in ·different forests and the role of principal herbaceous populations in its formation too. It was established that the herbaceous layer production is generally low in the analysed phytocoenosis and in inverse ratio with the density of little ageing seedlings layer and of shrubs ; in oak forest Cobia there are 94 kg/ha of dry matter in evergreen oak forests, 26 kg/ha at Cobia and 66 kg/ha at Ţiţeşti and in mixed beech and fir forests, 120 kg-152 kg/ha at Sinaia, according to wood production.
