Wzrastający popyt na piwa niszowe w Polsce spowodował zapotrzebowanie na słody pszeniczne, czego następstwem jest poszukiwanie rodzimych surowców do ich produkcji. Podjęte badania miały na celu określenie przydatności ziarna wybranych rodów pszenicy zwyczajnej do słodowania, ustalenie najważniejszych parametrów jakościowych ziarna, a także wskazanie kryteriów selekcyjnych dla hodowli. Zastosowano...
The biomass productivity of individual trees at age 14 years was investigated in the experiment with 8 provenances and 186 half−sib families of pedunculate oak (Quercus robur L.). The aim of the study was to develop allometric equations and estimate heritability of tree biomass. We sampled 28 model trees and measured dry mass of their components, including roots (on 14 trees). A decreasing share of...
Celem badań było określenie zawartości składników odżywczych i ocena właściwości przeciwutleniających całego ziarna, bielma, otrąb i łuski różnych odmian i rodów owsa. Materiałem badawczym było ziarno owsa o brązowej barwie łuski odmiany ‘Gniady’ i dwóch rodów: CHD 2875/01, CHD 2833/02, a także owies żółtoziarnowy odmian: ‘Bohun’, ‘Deresz’ i ‘Cwał’. Analizowano zawartość: suchej masy, białka, tłuszczu,...
Douglas−fir is the most important introduced forest tree species in Poland. It is included into the frame of the breeding program that needs to test the selected objects. In the described trial the families of 14 plus trees are being tested. They are half−sib families from the open pollination. The significant differences between the families were stated in case of the diameter at the breast height...
