1-Methylcyclopropene (1-MCP) is a new postharvest chemical application that attracting the attention of both scientists who studying upon agriculture and biology and people supported by agricultural industry world-wide. The scientific researches on this compound has shown it is a powerful inhibitor of ethylene action and capable of maintaining postharvest quality in many fresh horticultural products. According to numerous researchers, 1-MCP is interpreted that a universal ‘magic bullet’ that will cure many postharvest problems. 1-MCP is a tool that can help scientists make major advances in understanding the role of ethylene in plants. This plan growth regulator prevents ethylene effects in a broad range of fruits, vegetables and floriculture crops. Depending on the species being treated, 1-MCP may have a variety of effects on respiration, ethylene production, volatile production, chlorophyll degradation and other color changes, protein and membrane changes, softening, disorders and diseases, acidity and sugars.

YENİ BİR BİTKİ BÜYÜME DÜZENLEYİCİSİ: 1-METHYLCYCLOPROPENE (1-MCP)

Öz

1-Methylcyclopropene (1-MCP) tüm dünyada hem ziraat ve biyoloji ile çalışan bilim adamlarının
hem de ziraat ile geçimini sağlayan kişilerin dikkatini çeken yeni bir derim sonrası kimyasal uygulamadır.
Bilimsel çalışmalar 1-MCP’nin birçok bahçe ürünlerinde etilen hareketini engelleyerek derim sonrası
kalitenin korunmasında etkili olduğunu göstermektedir. Çok sayıda araştırmacıya göre 1-MCP birçok derim
sonrası problemlere deva olabilecek evrensel bir sihirli değnek olarak yorumlanmaktadır.1-MCP bitkilerdeki
etilen rolünü anlamada bilim adamlarına büyük gelişmeler kaydettirebilecek bir araçtır. Bu bitki büyüme
düzenleyicisi çok değişik meyvede, sebzede ve çiçekte etilen etkisini engellemektedir. Uygulanan türe göre,
1-MCP’nin etilen, solunum aroma miktarı, klorofil parçalanması ve diğer renk değişimleri, protein ve zar
değişimleri, meyve yumuşaması, hastalık ve bozukluklar, asitlik ve kuru madde üzerine değişik etkileri
vardır.
