Reproductive ability of Poa pratensis L. and P. angustifolia L. in conditions of Kazakhstan and Western Siberia

The article presents the seed productivity of five cultivars of Poa pratensis L. for lawn purposes and three wild-growing specimens of Poa pratensis L. and Poa angustifolia L. from natural populations in the south-east of Kazakhstan and in the south-west of Siberia, summarized over three years. The...
