Orchardgrass (Dactylis glomerata L.) is one of the essential foraging species which used as a cool-season persistent and perennial forage grass. This research was carried out during 2019 growing season in Eastern Anatolia region Turkey. The aim our to study morphologic characteristics natural assess genetic diversity collected genotypes determine best available for future breeding programs. In ...

Copper is a microelement involved in the metabolism of nitrogen compounds plants. Good utilization from soil and fertilizers by plants requires an adequate supply copper. The aim study was to determine effect increasing levels copper (100, 200, 300 mg Cu·kg−1 soil) applied together with various organic (cattle manure, chicken spent mushroom substrate) on content uptake cocksfoot (Dactylis glome...

Yaylacılık ülkemizde önemli bir gelenek olup, bu araştırma, 2014-2015 vejetasyon döneminde, Trabzon İli Düzköy İlçesi Yaylası (Kamema)’nın yaş ot ve botanik kompozisyonları ile birlikte florası incelenmiştir. Yayla (Kamena) çayırlarının verimleri 2.450-3.275 kg da-1 arasında değişmiş ağırlık esasına göre ise % 73 buğdaygiller + 12 baklagiller 15 diğer familyalardan oluşmuştur. Yapılan floristik...

Biochemically based models of C(3) photosynthesis can be used to predict that when photosynthesis is limited by the amount of Rubisco, increasing atmospheric CO(2) partial pressure (pCO(2)) will increase light-saturated linear electron flow through photosystem II (J(t)). This is because the stimulation of electron flow to the photosynthetic carbon reduction cycle (J(c)) will be greater than the...

1 We established monocultures and 16 unique mixed communities of 12 native grasses, legumes and non-N 2 -fixing forbs. We identified species having a greater or lesser yield in the mixed communities than expected from monoculture data as winners and losers, respectively. To test our hypothesis that performance of the subordinate species (losers) is mainly controlled by light availability, where...
