Capsicum baccatum var. pendulum (cv. MKÜ-19) TOHUMLARINDA ALLELOPATİK MATERYALLER İLE UYGULAMALARIN ÇIKIŞ VE FİDE KALİTESİNE ETKİSİ

Allelopatik kimyasalların tohum uygulamalarındaki uyarıcı etkileri, engelleyici etkileri kadar önemlidir. Bu nedenle ferula (çakşır) bitkisinden elde edilen sakız (FER, 0.2 g sakız/L, 25℃, 24saat), mine çalısı (LAN, 4 g kurutulmuş petal/L, 25℃, 24 saat) ve kadife çiçeği (TAG, 4 g kurutulmuş petal/L, 25℃, 24 saat) bitkilerinin çiçeklerinden elde edilen demleme çaylarının MKÜ-19 (Capsicum baccatum var. pendulum) biber genotipi tohumlarında priming materyali olarak etkisi araştırılmıştır. Allelopatik materyallerin ekim öncesi etkisini belirleyebilmek için, uygulama yapılmış ve uygulama yapılmamış tohumlarda çıkış oranı (%), ortalama çıkış süresi (gün), çıkış indeksi, çıkış hız katsayısı (%), fide boyu (cm), fide yaş ağırlığı (mg) ve fide kuru ağırlıkları (mg) belirlenmiştir. Sonuçlar allelopatik bitki ekstraktları ile yapılan tohum uygulamalarının fide kalitesini arttırdığını göstermektedir. Allelopatik TAG uygulamasının kontrole göre fide boyunu 1.74 cm arttırdığı, fide yaş ağırlığını 161 mg arttırdığı ve fide kuru ağırlığını 15.3 mg arttırdığı tespit edilmiştir. FER ve LAN uygulamaları da kontrol tohumlarına göre fide performansında önemli etkilere sebep olmuşlardır. Ancak tohumların başlangıç kalitesinin yüksek olması nedeniyle çıkış oranı, ortalama çıkış süresi ve çıkış indeksinde uygulamaların etkisi düşük kalmıştır. Yine de sonuç olarak allelopatik materyallerle yapılan tohum uygulamaları ucuz, organik, çevre dostu, etkili ve basit uygulanabilir olmaları nedeniyle farklı genotiplerde de etkinliğinin belirlenmesi önerilebilir. Ayrıca bu materyallerin tohum ekiminde antifungal ve anti bakteriyel etkilerinin araştırılması, kullanımlarını da arttırabilir.

THE EFFECTS OF ALLELOPATHIC MATERIALS TREATMENTS ON EMERGENCE AND SEEDLING QUALITY OF Capsicum baccatum var. pendulum (cv. MKÜ-19) SEEDS

Stimulating effects of allelopathic chemicals in seed applications are as important as inhibitory effects. Therefore, the effect of herbal teas obtained from the flowers of lantana shrub (LAN, 4 g dried petal/L, 25℃, 24h) and marigold plants (TAG, 4 g dried petal/L, 25℃, 24h) also gum obtained from ferula plant (FER, 0.2 g gum/L, 25℃, 24h) as priming material in MKU-19 (Capsicum baccatum var. pendulum) pepper genotype seeds was investigated. The pre-sowing influence of allelopathic material (TAG, LAN and FER) on the emergence percentage (%), mean emergence time (days), emergence index, coefficient of velocity of emergence (%), seedling length (cm), seedling fresh weight (mg) and seedling dry weight (mg) investigated in MKÜ-19 pepper seeds. The results showed that seed treatments with allelopathic plant extracts increased seedling quality. Allelopathic TAG treatment was found to increase seedling length by 1.74 cm, seedling fresh weight by 161 mg and seedling dry weight by 15.3 mg. FER and LAN treatments also caused significant effects on seedling performance compared to control seeds. However, due to the high initial quality of seeds, the effect of allelopathic treatments on emergence percentage, mean emergence time and emergence index remained low. However, as a result, seed treatments with allelopathic materials can be suggested to determine the effectiveness of different genotypes because they are cheap, organic, environment friendly, effective and simple applicable. In addition, investigating the antifungal and antibacterial effects of these materials in seed sowing may increase their use.
