The changes of yield and essential oil components of German Chamomile (Matricaria recutita L.) under application of phosphorus and zinc fertilizers and drought stress conditions.

摘要: Abstract In order to investigate the effect of drought stress and phosphorus zinc fertilizers on physiological traits, yield essence components German chamomile (Gural cultivar), a split plot factorial experiment was conducted based randomized complete block design with three replications at Research farm University Zabol in 2013. Drought consisted levels 75% (control), 50% (mild stress) 25% field capacity (severe as main plots, combinations triple superphosphate fertilizer (CaH 4 P 2 O 8 ) (0, 150, 300 kg ha −1 two sulfate (ZnSO H O) (0 30 kg ha subplots. Studied traits were included carbohydrate, prolin, carotenoid, essential oil percentage, yield, chamanzulene content, β-farenzn, bisabolo oxide A, B. The results showed significant all studied whereas application B, content. Also can note that high (300 kg ha had negative effects chamomile. general, suggest irrigation 150 kg ha 30 kg improve medicine oil.
