Abstract

Asmalarda tomurcuk dinlenmesi ve dinlenmeyi kesen maddeler incelenmiştir. Hidrojen siyanamid tomurcuklarda ve tohumlarda dinlenmeyi kesen yeni geliştirilmiş bir bitki büyüme düzenleyicisidir. Hidrojen siyanamidin bitkiler tarafından alınma metabolizması, kimyasal ue fiziksel özellikleri açıklanmıştır.
Hidrojen siyanamid, aşağıda belirtilen amaçlar için asma gözlerinin uyanmasında kullanılabilir:
1. Erken uyanma yoluyla üzümlerin olgunlaşmasını öne almak,
2. Uzun budanan çeşitlerde uyanmayan göz sayısını azaltmak,
3. Tropik e subtropik bölgelerde uyanmayı düzenleyerek yılda iki ürün almak.

Use of Hydrogen Cyanamidc in Budbreak of Grapevines

Abstract

Bud dormancy of grapevines and dormancy breakers were studied. Hydrogen cyanamide is a newly developed plant regulator which breaks dormancy in buds and seeds. Chemical and physical properties and uptake metabolism by plants of hydrogen cyanamide were explained.
Hydrogen cyanamide can be used in budbreak of grapevines for some purposes as follows:
1. To advance the maturity of grapes by early budbreak,
2. To decrease the ratio of blind buds in cane pruned cultivars,
3. To harvest two crops per year regulating budbreak in tropical and subtropical regions.

Keywords
