Abstract

In order to study the effects of drought stress and seed pretreatment of two maize varieties with Cycocel anexperiment was carried out with the aim to reduce the stress on the yield of this crop during their critical growthstages.Field trials were arranged in split-split plot design and randomized complete block design with threereplications. For statistical evaluation, irrigation as the main factor at four levels (complete irrigation as the controland eliminating one stage of irrigation at the beginning of stalking, tasseling and dough stages), maize var. KSC704and KSC666 as the sub factor at two levels and application of Cycocel as the sub-sub factor at three levels (0,0.4, and 0.8 g L-1 concentration) were created.Eliminating one stage of irrigation in stalking and tasseling stagesaffected the ear length, ear diameter, grain number per ear, grain number per row and ultimately the grain yield,while the drought stress at dough stage had no significant difference in the results of the experiment comparedto the control group. Apart from enhancing 1000-grain weight, the use of Cycocel pretreatment affected the testresults slightly and comparison of these findings with similar studies, which applied Cycocel as foliar, indicatesthe higher ability of foliar than the pretreatment.

Özet

Bu deneme iki farklı mısır varyetesinde, bitkinin en hassas büyüme ve gelişme dönemlerinde kuraklık stresi vetohumlara bitki büyüme düzenleyici olarak Cycocel muamelesinin verim üzerine etkilerinin en aza indirmekamacıyla kurulmuştur. Deneme Split-split Plot Deneme Desenine göre 3 tekrarlamalı olarak yürütülmüştür.İstatistiksel değerlendirmede, sulama ana parselleri dört düzeyde (düzenli sulama kontrol ve sapa kalkma dönemi,çiçeklenme dönemi ve danelerin hamurlaşma döneminin başında bir nöbet sulama kesintisi), mısır varyetesi altparselleri iki düzeyde (KSC704 ve KSC666) ve Cycocel uygulaması alt-alt parsellerini üç düzeyde (0, 0.4, and 0.8g L-1 concentration) oluşturmuştur. Kontrol bitkilerle karşılaştırıldığında sapa kalkma ve çiçeklenme dönemlerininbaşında bir nöbet su kesimi koçan uzunluğu, koçan çapı, koçanda dane sayısı, her sırada dane sayısı ve daneverimini olumsuz etkileyerek, dane hamurlaşma dönemi kuraklık stresinden etkilenmemiştir. Mısır tohumlarındaCycosel uygulaması 1000 dane ağırlığı yükselişi hariç, deneme sonuçlarını çok az etkilemiştir. Bu bulgular diğerbenzeri araştırma sonuçlarıyla karşılaştırıldığında yapraktan uygulama Cycocel yöntemi, tohum uygulamasındandaha etkilidir.
