Abstract

This study was conducted to determine the effects of squares and flowers removal on flower distribution on plant, flowering pattern, square and flower shedding rates and boll retention rate of cotton plant (Gossypium hirsutum L.). Field experiments were conducted at research field of the Harran University Faculty of Agriculture, Department of Field Crops in years of 1998 and 1999 at southeastern of Turkey. Experiments were arranged in completely randomized block design with four replications. The Sayar 314 cotton (G. hirsutum L.) variety was used as plant material.  Squares were removed through first two weeks of squaring (SR1-2), and flowers were removed with two weeks intervals from flowering initiation to the end of the tenth week of flowering (FR1-2, FR3-4, FR5-6, FR7-8, FR9-10) and control. Effects of removal treatments on investigated traits were different. In general, effects of FR7-8 and FR9-10 were similar to control on most of the investigated traits. SR1-2, FR1-2 and FR3-4, have changed the flowering pattern and plants reached peak flowering later than control and addition to these treatments FR5-6 has lightened or perevented cut-out, too. Square and flower removals increased the numbers of square and flower in both years. Square numbers were increased from 78.6 to 84.9 and 79.0 to 86.1  per plant by SR1-2 in 1998 and 1999, respectively. Flower numbers increased from 58.38 to 65.00 and 59.53 to 65.30 per plant in FR3-4, in 1998 and 1999, respectively. Square shedding rate was reduced by removal treatments. Boll retention rate was increased by removal treatments. Also, percentage of flower and shedding square, and boll retention rate on positions of fruiting branches were affected by removal treatments.

Abstract

Bu çalışma, 1998 ve 1999 yıllarında, pamukta (Gossypium hirsutum L.) tarak ve çiçek uzaklaştırmanın
çiçeklenme düzeni, tarak ve çiçek silkme oranı ve koza tutma oranı üzerine etkisinin saptanması
amacıyla, HR.Ü. Ziraat Fakültesi Tarla Bitkileri Bölümü araştırma alanında, tesadüf blokları deneme
deseninde dört tekrarlamalı olarak yürütülmüştür. Bitki materyali olarak, Sayar 314 pamuk çeşidi
kullanılmıştır. Çalışmada, taraklanma başlangıcından itibaren iki hafta boyunca oluşan tarakların (SR1-2),
çiçeklenme dönemi başlangıcından başlayarak 10 hafta boyunca, ikişer hafta süreyle oluşan çiçeklerin
(FR1-2, FR3-4, FR5-6, FR7-8, FR9-10) uzaklaştırılması ve Kontrol olmak üzere 7 konu uygulanmıştır.
Generatif organ uzaklaştırmanın incelenen özelliklere etkisi farklı olmuştur. Genel olarak, FR7-8 ve FR9-
10’un etkileri diğer uygulamalara göre kontrola benzer olmuştur. SR1-2, FR1-2 ve FR3-4 çiçeklenme
düzenini değiştirmiş ve kontrolden daha geç çiçeklenme pik yapmıştır, ayrıca bu uygulamalara ek olarak
FR5-6 uygulamalarında cut-out dönemi hafif olmuş veya önlenmiştir. Tarak ve çiçek uzaklaştırmalar her
iki yılda da tarak ve çiçek sayısını artırmıştır. Tarak sayısı, SR1-2 uygulamasında 1998 ve 1999 yıllarında,
sırasıyla bitki başına 78.6’den 84.9’a ve 79.0’dan 86.1’a artmıştır. Çiçek sayısı, FR3-4 uygulamasında, 1998 ve 1999 yıllarında, sırasıyla bitki başına 58.38’den 65.00’a ve 59.53’den 65.30’a yükselmiştir. Tarak
silkme oranı, uzaklaştırma uygulamalarına bağlı olarak azalmıştır. Koza tutma oranı ise, uzaklaştırma
uygulamalarına bağlı olarak artmıştır. Aynı zamanda, tarak ve çiçek silkme oranı ve meyve dallarına göre
koza tutma oranı uzaklaştırma uygulamalarından etkilenmiştir.
