Ölümcül sıcaklıklar ve soğuğa dayanımdaki farklılıklar farklı geliĢim evrelerinde gözlenmiĢtir. Gözlenen hasar çiçek tomurcuğu geliĢim evrelerine yüksek oranda bağlıdır. Tomurcukların düĢük sıcaklıklara karĢı artan bir hassasiyeti olduğu gözlenmiĢtir. Çiçek toleransı erken çiçek tomurcuğu evresi ve çiçeklenme boyunca sıcaklık dalgalanmasından etkilenir, sıcak Ģartlar çiçek hassasiyetini artırırken, düĢük sıcaklık bu Ģartı azaltır. Maksimum dayanıklılığın belirlenmesi genetik olarak elde edilebilmesine rağmen, iklimsel etkinin bir sonucu olarak daha fazla yıllar içerisinde süren gözlemlere ihtiyaç vardır. Dinlenme halindeki viĢne çiçek tomurcukları için öldürücü sıcaklık -16°C iken, açılmamıĢ çiçek tomurcuğu evresinde -11°C’ye doğru hızlı bir Ģekilde yükselmiĢtir.
Konya il merkezinde ekonomik viĢne yetiĢtiriciliğinde özellikle dinlenme döneminde meydana gelebilecek extrem düĢük sıcaklıklar bazı yıllarda viĢne çiçek tomurcuklarına zarar verebilir. Bu itibarla kapama bahçeler kurulurken mümkün olduğu kadar soğuk havanın biriktiği çukur alanlardan kaçınmak, mümkün olduğu kadar korunaklı alanların tercih edilmesi önerilebilir.
