Anne-Sürgün Yönteminin Kuşkonmaz Verimi ve Kalitesi Üzerine Etkileri

Bu çalışmada, ‘UC 157’ F1 çeşidine ait 5 yaşındaki kuşkonmaz(Asparagus officinalis L.) bitkileri materyal olarak kullanılmış ve2017 ve 2018 yıllarında hasat periyodunun farklı zamanlarındabırakılan anne sürgünlerin sürgün sayısı ve kalitesi üzerine etkileribelirlenmiştir. Kuşkonmaz bitkilerinin bir kısmı anne sürgünbırakılmaksızın 4 veya 6 hafta süreyle hasat edilmiştir. Ayrıca,bitkilerin bir kısmı da 3 farklı zamanda (hasadın başında, hasatbaşladıktan 2 hafta sonra ve hasat başladıktan 4 hafta sonra) annesürgün bırakılarak toplamda 6 hafta süreyle hasat edilmiştir.Sonuçlar incelendiğinde hasadın başlamasından 4 hafta sonra annesürgün bırakılan bitkilerden hiç anne sürgün bırakmadan 6 haftaboyunca hasat edilen bitkilere kıyasla %9-13 oranında daha fazlapazarlanabilir sürgün elde edilmiştir. Ayrıca her iki yılda da eldeedilen pazarlanabilir sürgünlerin kalite sınıflandırılması dikkatealındığında, yine aynı uygulamadan daha az oranda ince (8-12 mmçap) sürgün elde edildiği; buna karşılık piyasada en çok talep edilensürgün kalınlığı olan 12-16 mm ile 16-20 mm arasındaki sürgünlerinoranının ise yükseldiği görülmüştür. Bu sonuçlara göre, 4 hafta sürenhasadı takiben anne sürgün bırakma yönteminin Kahramanmaraşkoşullarında yapılacak olan kuşkonmaz yetiştiriciliğinde hempazarlanabilir sürgün sayısını hem de sürgün kalitesini arttırmadaetkili olduğu söylenebilir.
