Effects of salt applications on growth and development of ornamental cabbage (Brassica oleracea var. acephala)

Abstract

This study was conducted during 2024 and 2025 to determine the effects of varying doses of salt application to the growing medium on the growth, and development of ornamental Cabbage (Brassica oleracea var. acephala) plants. Different salinity doses (EC 0 mM (Control), EC 25 mM, EC 50 mM, EC 100 mM and EC 200 mM) were applied to the growth medium (70% peat + 30% perlite). Data relating to plant height (cm), head diameter (mm), root length (cm), number of leaves (number), leaf length (cm), leaf width (cm), stem wet weight (g), stem diameter (mm), stem length (cm), root dry-wet weight (g), leaf wet-dry weight (g), chlorophyll index (Spad), proportional water (%), ion flow (%), and cell membrane damage rate (%) were collected. Results revealed that increasing salt concentrations raised relative water content, ion flow, and cell membrane damage rate compared to the control. However, control treatment gave better results for other analysed traits. It was observed that there were proportional decrease in the treatments in parallel with the increase in salinity doses.

Tuz uygulamalarının süs lahanası (Brassica oleracea var. acephala) bitkisinin büyüme ve gelişimine etkileri

Abstract

Bu çalışma, yetiştirme ortamına farklı dozlarda tuz uygulamasının Süs Lahanası (Brassica oleracea var. acephala) bitkisinin büyüme ve gelişimine etkilerini belirlemek amacıyla 2024-2025 yılları arasında yürütülmüştür. Çalışmada, yetiştirme ortamına (hacim esasına göre %70 torf + %30 perlit) farklı dozlarda tuz (EC 0 mM (Kontrol), EC 25 mM, EC 50 mM, EC 100 mM ve EC 200 mM) uygulanmıştır. Bu çalışmada, bitki boyu (cm), baş çapı (mm), kök uzunluğu (cm), yaprak sayısı (adet), yaprak boyu (cm), yaprak eni (cm), gövde yaş ağırlık (g), gövde çapı (mm), gövde uzunluğu (cm), kök yaş-kuru ağırlık (g), yaprak yaş-kuru ağırlık (g), klorofil indeksi (Spad), oransal su (%), iyon akışı (%) ve hücre zarı zarar oranı (%) gibi parametreler incelenmiştir. Çalışma sonunda, uygulamalar arasında, oransal su kapsamı, iyon akışı ve hücre zarı zarar oranı bakımından tuz konsantrasyonları arttıkça bu değerlerde kontrole kıyasla artmıştır. Ancak diğer incelenen parametreler açısından, kontrol uygulamalarının daha iyi sonuç verdiği; Tuz uygulama dozlarının artmasına paralel olarak uygulamalarda oransal olarak azalmalar olduğu gözlenmiştir.
