Özet
Bu çalışmada, domatesin önemli sorunlarından olan canavarotu (O.mmosa L.)'na karşı bazı bitki parçalarının allelopatik etkileri araştırılmıştır. Toprakta 1 ay bekletilen bitkilerden, cevizin % 1'lik dozunda O.ramosa çıkışının en yüksek (3.8 adet), karnabaharın % 5'lik dozunda ise çıkışın en az (0.4 adet) olduğu görülmüştür. Toprakta 2 ay bekletilen bitkilerden ceviz, lahana, karnabahar ve tespih ağacı bitkilerinde çıkışlar 1. aya göre daha yüksek bulunmuştur. En fazla çıkış 67.2 adet ile lahananın % l'lik dozunda, en az çıkış ise 1.8 adet ile zakkumun % 5'lik dozunda görülmüştür. Kontroldeki ort. çıkış ise 12.5 adettir. Toprakta 3 ay bekletilen bitkilerden, karnabaharın % l'lik dozunda çıkış en yüksek (21.4 adet) bulunurken, zakkumun hiçbir dozunda çıkış görülmemiştir. Kontroldeki ort.çıkış 9.7 adettir. Denemeye alman bitkilerin toprakta 2 aylık bekletilmeleri sonucunda, canavarotu çıkışları daha yüksek bulunmuştur. Testlenen bitkilerin 1 ve 3 ay bekletilmelerinin, O.ramosa gelişimini azaltabileceği kanısına varılmıştır.
In this study, allelopathic effects of some plant materials on the growth of branched broomrape {Orobanche ramosa) was investigated. in case of plant material incorporated to and kept in soil for one month, maximum emergence (3.8 no.) in walnut and minimum emergence (0.4 no.) in cabbage treatments was observed at doses of 1 % and 5 % respectively. the number of emergenced branches of O.ramosa was 6.5 innontreated control. in treatments with plant material (walnut, cabbage, cauliflower and beads tree) kept in soil for two months the branched broomrape emergence was higher as compared to that kept for one month. Maximum number of emergenced O.ramosa branches (67.2 no.) in cabbage treatment at dose of 1 % and minimum (1.8 no.) in oleander treatment at dose of 5 % was observed. in control, the average of number of emergenced branches of O.ramosa was 12.5. in the treatment with cauliflower material kept in soil for 3 months at a dose of 1 %, maximum branched broomrape emergence (21.4 no.) was observed, wheras in oleander treatment no branched broomrape emergence was observed at any dose. in control an average of 9.7 no. branched broomrape was recorded. the emergence of branched broomrape was found to be higher in treatments with plant materials kept in soil for 2 months. the plant material kept in soil for 1 and 3 months has been found to reduce the growth of O.ramosa effectively.
