Abstract

Pendimethalin herbicide is widely used for controlling weeds in agricultural applications. However, the side effect of pendimethalin on cultivated plants is unknown. In this study, oxidative stress induced by pendimethalin in safflower plant (Carthamus tinctorius L.) was investigated. In this study, oxidative stress induced by pendimethalin in Dinçer and Remzibey cultivars of safflower was investigated. The herbicide was applied after germination at the doses determined (0.004-0.01 M) following toxicity tests to the leaves of plants of suitable size (21 days). In application groups, carotenoids, total chlorophyll, total carbohydrate, total phenolic and malondialdehyde (MDA) content indicating lipid peroxidation were investigated. The content of carotenoid in Dinçer (42.7 %) and Remzibey (59 %) cultivars decreased compared to control. Total chlorophyll content was significantly higher in Remzibey cultivar (56.8 %) than Dinçer cultivar (41.4 %). In Dinçer cultivar (50 %), carbohydrate content was found to be higher than Remzibey cultivar (46.1 %). Total phenolic content decreased with increasing hours in Remzibey (48.3 %) and Dinçer (46.7 %) cultivars. MDA content was higher in Remzibey cultivar (72.4 %) than Dinçer cultivar (70.1 %). This study has shown that pendimethalin herbicide has a toxic effect on safflower, which is a cultural plant.

Özet

Pendimethalin herbisiti tarımsal uygulamalarda yabancı otların kontrolü için yaygın olarak kullanılmaktadır. Bununla birlikte, pendimethalinin kültür bitkileri üzerindeki yan etkisi tam olarak bilinmemektedir. Bu çalışmada, aspir (Carthamus tinctorius L.) bitkisine ait Dinçer ve Remzibey çeşitlerinde pendimethalin kaynaklı oksidatif stres araştırıldı. Herbisit uygun büyüklüğe (21 günlük) gelen bitkilerin yapraklarına toksisite denemeleri sonrasında belirlenen dozlarda (0.004-0.01 M) çimlenme sonrası olarak uygulandı. Uygulama gruplarında karotenoid, toplam klorofil, toplam karbohidrat, toplam fenolik ve lipid peroksidasyonunu gösteren malondialdehid (MDA) içeriğindeki değişimler saptandı. Dinçer (% 42.7) ve Remzibey (% 59) çeşitlerinde karotenoid içeriği kontrole kıyasla azalış gösterdi. Toplam klorofil içeriği Remzibey çeşidinde (% 56.8) Dinçer’e (% 41.4) göre daha yüksek bulundu. Toplam karbohidrat içeriği Dinçer çeşidinde (% 50) Remzibey çeşidine (% 46.1) kıyasla daha yüksek saptandı. Toplam fenolik içeriği Remzibey (% 48.3) ve Dinçer (% 46.7) çeşitlerinde artan saatlere bağlı olarak azalış gösterdi. MDA içeriği Remzibey çeşidinde (% 72) Dinçer çeşidine (% 70) göre daha yüksek saptandı. Bu çalışma, pendimethalinin kültür bitkisi olan aspire toksik etki oluşturduğunu göstermiştir.
