Paclobutrazolun Bougainvillea glabra 'Sanderiana'nın Büyüme ve Çiçeklenmesi Üzerine Etkileri

Year 2002, Volume: 15 Issue: 1, 79 - 84, 01.06.2002

Abstract

Bu çalışmada paclobutrazolun sabit gündüz/gece sıcaklıkları (25/15°C) ve iki farklı yetiştirme döneminin doğal fotoperiyot koşullarında Bougainvillea glabra ‘Sanderiana’nın büyüme ve çiçeklenme özelliklerine etkisi araştırılmıştır. Yaz ortası-geç sonbahar ve geç sonbahar-erken ilkbahar yetiştirme dönemleri için, budamalardan 31 ve 33 gün sonra, 14 Temmuz ve 16 Kasım tarihlerinde bitkilere 0 (kontrol), 5, 10, 20, 30 ve 40 mg/bitki dozunda paclobutrazol yapraktan ve topraktan olmak üzere iki farklı yöntemle uygulanmıştır. Paclobutrazol uygulamalarının çiçeklenmeye kadar geçen süre üzerine etkisi sadece yaz ortası-geç sonbahar yetiştirme döneminin doğal fotoperiyot koşullarında ortaya çıkmış ve toprak uygulamalarında 20 mg/bitki, yaprak uygulamalarında ise 20 ve 30 mg/bitki paclobutrazol dozları çiçeklenmeye kadar geçen süreleri sınırlı biçimde kısaltmış, buna karşın geç sonbahar-erken ilkbahar döneminde yetiştirilen bitkilerin uygulamalardan etkilenmeksizin çiçeklenmek için daha kısa sürelere ihtiyaç duydukları gözlenmiştir. Paclobutrazolun doz artışına paralel olarak artan bir etkiyle sürgün uzunluklarını kısalttığı ve toprak uygulamalarının boğum arası ve sürgün uzunlukları üzerinde daha uzun süreli ve güçlü bir kısaltıcı etkiye sahip olduğu saptanmıştır. Bitki başına sürgün sayıları yaprak uygulamalarıyla artmış, toprak uygulamaları ise sürgün sayılarının azalmasına neden olmuştur. 5 ve 10 mg/bitki dozlarındaki paclobutrazol uygulamalarının her iki yetiştirme döneminde de bitki başına çiçek sayılarını artırdığı, ayrıca daha küçük boyutlu olmalarına karşın geç sonbahar-erken ilkbahar döneminde yetiştirilen bitkilerin daha fazla çiçek oluşturduğu belirlenmiştir.

Influence of Paclobutrazol on The Growth and Flowering of Bougainvillea glabra 'Sanderiana'

Year 2002, Volume: 15 Issue: 1, 79 - 84, 01.06.2002

Abstract

In this study, effects of paclobutrazol on the growth and flowering of Bougainvillea glabra 'Sanderiana' under constant day/night (25/15°C) temperatures and natural photoperiods of two growing periods were investigated. For mid summer to late autumn and late autumn to early spring growing periods, 31 and 33 days after pruning, paclobutrazol at 0 (control), 5, 10, 20, 30 and 40 mg/plant were applied as soil drench and foliar spray on 14 July and 16 November, respectively. Slight shortening effects on the time to flowering were observed with 20 mg/plant dose in the soil drench, and 20 and 30 mg/plant doses in foliar spray treatments in only mid summer to late autumn period. Plants grown in late autumn to early spring period needed shorter time to flower with out any effect of treatments. Paclobutrazol reduced branch length with greater effect at increasing doses and soil drench treatments had stronger effect and longer suppressing duration on internodes and branch lengths. The branch numbers increased with foliar sprays, and decreased with soil drench treatments. 5 and 10 mg/plant paclobutrazol increased the flower numbers per plant in each growing period. Also flower numbers was higher in plants grown in late autumn to early spring period, although they had smaller canopy.
