The Investigation of Effects of Pre-Harvest Rainfall on Lint Color Grade and Seed Germination Rate in Cotton (Gossypium hirsutum L.)
Abstract
Unexpected rainfall in harvest season has a detrimental effect on cotton lint color grade and germination rate and cause economic losses for farmers, seed producers and manufacturers. This study was conducted to elucidate the effects of different rainfall amounts on cotton technological characteristics and to evaluate the response of different cultivars in the harvest season of 2014 and 2015. Cotton bolls were exposed to 0 (control), 20, 35, 65, 95 and 125 mm of precipitation. The effects of rainfall were determined in GSN-24, Claudia, Gloria, ST-373, Flash, Carisma and ST-468 cotton cultivars (Gossypium hirsutum L.). The responses of cultivars to different cumulative rainfall were significant for lint color grade and seed germination rate. The linear curve in the decreasing direction according to the highest R2 value was evaluated for germination rate (%), reflectance (Rd), trash count and trash area (%) whereas the polynomial curve was more likely for yellowness (+b). The effects of increased rainfall amounts on all observed characters were unfavorable. The different responses of cultivars indicated that the cultivars with the least loss for lint color grade and germination rate in seed production could be recommended in terms of being highly profitable.

Pamukta (Gossypium hirsutum L.) Hasat Öncesi Yağışların Çimlenme ve Elyaf Renk Değerleri Üzerine Etkisi
Abstract
Hasat döneminde gerçekleşen yağışlar pamukta elyaf renk derecesi ve tohum çimlenme oranını olumsuz etkilemekte ve çiftçi, tohumluk üreticisi ve tekstilci için ekonomik kayıplara neden olmaktadır. Bu çalışma hasat öncesi farklı miktarlarda oluşan yağışların pamukta lif teknolojik özelliklerine olan etkisini ve farklı çeşitlerin yağışlara olan tepkilerinin belirlenmesi amacıyla 2014 ve 2015 yıllarında yürütülmüştür. Kozalar kontrol (0 mm) ile birlikte 20, 35, 65, 95 ve 125 mm yağışa maruz bırakılmıştır. Yağışın GSN-24, Claudia, Gloria, ST-373, Flash, Carisma ve ST-468 çeşitlerine etkisi belirlenmiştir. Çeşitlerin elyaf renk değeri ve çimlenme oranı bakımından toplam yağışa olan tepkileri önemli bulunmuştur. En yüksek belirleme katsayısına (R2) göre çimlenme oranı (%), yansıma (Rd), yabancı madde miktarı ve alanı (%) yönünden azalan düzeyde doğrusal regresyon eğrisi, buna karşın sarılık (+b) için polinomiyal eğri bulunmuştur. Çalışmanın sonucunda yüksek kazanç için lif kalite değerleri yağış miktarından olumsuz yönde daha az etkilenen ve çimlenme oranı kaybı en az olan çeşitlerin önerilebileceği sonucuna varılmıştır.
