Bor uygulamasının şeker pancarında çimlenme ve erken gelişim dönemindeki etkilerinin araştırılması

Şeker pancarı (Beta vulgaris L.), küresel ölçekte önemli ve stratejik bir üründür. Pancar bitkisinin bor (B) ihtiyacının yüksek olmasına rağmen, B uygulamalarının çimlenme ve fide gelişimine etkisi hakkında fazla bir veri bulunmamaktadır. Bu araştırma, B elementinin şeker pancarı tohumlarının çimlenme ve fide gelişmesine etkilerini incelemek için laboratuar koşullarında yürütülmüştür. Deneme tesadüf parselleri deneme desenine göre üç tekerrürlü olarak kurulmuştur. Çalışmada 'BR1' şeker pancarı çeşidine beş farklı dozda B (0, 0.2, 0.4, 0.8, 1.6 ppm) uygulanmıştır. Varyans analizine (ANOVA) göre çalışmada incelenen kök uzunluğu, fide yüksekliği, fide kuru ağırlığı ile sürme hızı ve sürme gücü bor uygulamalarından önemli ölçüde etkilenmiştir. Çalışma sonunda 0.2 ppm B uygulamasının BR1 şeker pancarı çeşidinin kök uzunluğu, fide uzunluğu, fide kuru ağırlığı, sürme hızı ve sürme gücü özellikleri üzerine olumlu etkisi olduğu belirlenmiştir. Bununla birlikte, 1.6 ppm B uygulamasının ise incelenen parametrelerin tamamında şeker pancarı fidelerinde olumsuz etki oluşturduğu tespit edilmiştir.

Investigation of the effects of boron application on germination and early seedling development of sugar beet

Sugar beet (Beta vulgaris L.) is a major source of sugar on a global scale. Despite the fact that the sugar beet crop has a high need for boron (B), there is little data on the effect of B applications on germination and seedling growth. A laboratory experiment was conducted to examine the effects of boron application on sugar beet germination, and seedling stage. The experiment was arranged in completely randomized design with three replications. Cultivar ‘BR1’ was treated with five levels of boron (0, 0.2, 0.4, 0.8, 1.6 ppm) for the experiment. According to analysis of variance (ANOVA). It was found that the root length, seedling height, seedling dry weight as well as seedling emergence rate and seedling emergence vigour were considerably affected by boron administrations. As a result, 0.2 ppm boron application had a positive effect on the root length, seedling height, seedling dry weight, seedling emergence rate and seedling emergence vigour. However, 1.6 ppm boron application had a negative effect on investigated traits.
