The formation of aerenchyma in adventitious roots is one the most crucial adaptive traits for waterlogging tolerance plants. Pasture grasses, like other crops, can be affected by waterlogging, and there scope to improve through breeding. In this study, two summer-active cocksfoot (Dactylis glomerata L.) cultivars, Lazuly Porto, tall fescue (Lolium arundinaceum Schreb., syn. Festuca arundinacea ...

Aphids feed on plant phloem sap, rich in sugars but poor in essential amino acids. However, sugars cause osmotic regulation problems for aphids, which they overcome by hydrolysing the sugars in their gut and polymerising the hydrolysis products into oligosaccharides, excreted with honeydew. Aphids harbour primary bacterial endosymbionts, which supply them with essential amino acids necessary fo...

The most important task for the further development of animal breeding is increase production feed, its quality and reduction costs. Important thing in these conditions parallel two areas - creation highly productive agrocenoses technologies capable saving obtained feed mass future use during winter period. A valuable component grass mixtures when creating hayfields North-West region cocksfoot ...
