Bu çalışmada, katı matriks priming uygulamalarının yaşlandırılmış 25 lahana tohum partisinde çimlenme, çıkış, ortalama çimlenme ve çıkış hızı ile birlikte elektiriksel iletkenlik testine olan etkisi incelenmiştir. Katı matriks priming koşullarında 1:2:2.5 tohum, vermikülit ve su karışımı ortamında olmak üzere tohumlar 16 saat karanlık ve 25 °C’de uygulanmıştır. Matriks priming uygulamasının çimlenme ve çıkışı artırdığı, ortalama çimlenme, çıkış hızı ile akıntıyı azalttığı tespit edilmiştir. Matriks priming’in etkisinin yaşlanmamış tohumlara oranla yaşlı tohumlarda daha avantajlı olduğu belirlenmiştir. SMP’nin yaşlı lahana tohumlarında tohum kalitesini artırdığı sonucuna varılmıştır

Solid Matrix Priming of Cabbage Seed Lots: Repair of Ageing and Increasing Seed Quality

Öz

This study was conducted to determine the effect of solid matrix priming treatment on 25 cabbage seed lots of various ages in terms of enhanced germination, emergence, mean germination and emergence time, and electrical conductivity. Solid matrix priming at a seed: vermiculite: water rate of 1:2:2.5 w:w:w was applied at 25 °C for 16 hours in the dark. Matrix priming was found to increase germination and emergence, reduced mean germination, emergence times and solute leakage. The advantages of solid matrix priming were observed more in aged than fresh seeds. The results indicated that SMP may enhance aged cabbage seed quality
