Anther Culture Potential Of Linseed ( Linum Usitatissimuml.):Effects Of Genotypes And Pretreatment On Callusformation And Differentiation, Orhan Kurt, Gareth. M. Evans

Turkish Journal of Agriculture and Forestry

This study is concerned with the production of haploids of linseed. Anthers of eight genotypes were cultured both on solid and in liquid medium. It was found that callus induction rate was low in both media and also the cultivars significantly affected callus induction rate both on solid and in liquid medium. The cultivar Blue-Chip gave, on average, the maximum (3.67%) callus induction rate on solid medium and the cultivar Antares gave, on average, the maximum (3.35%) callus induction rate in liquid medium. The cultivar Norman produced callus on solid medium but did not produce any callus in liquid medium. …

Influence Of Natural Zeolite On Performance Of Laying Hens And Egg Quality, Ergin Öztürk, Güray Erener, Musa Sarica

Turkish Journal of Agriculture and Forestry

This experiment was conducted to study the effects of natural zeolite on the performance of laying hens. One hundred and eighty 37-week-old Babcock B-300 hens were fed with a diet containing 0, 20, 40, 60 and 80 g clinoptilolite/kg in an experiment consisting of 36 hens per treatment during a 4x28 days experimental period. All feeding programs were isocaloric and isonitrogenous. Hens were put at random into 5 treatment groups (12 replicates and 36 hens per treatment). No significant dietary effects were observed in terms of body weight, feed consumption, feed efficiency ratio, the number of eggs laid per hen, …
