Özet
Tuzluluk, dünyamızda verimli tarımı tehlikeye sokarak besin ürünlerinin üretimini önemli düzeyde kısıtlayan çevresel stres faktörlerinden birisidir. Dünya yüzeyinde bulunan alanların yaklaşık % 6'sı tuzluluk sorunu ile karşı karşıyadır. Ülkemizde yaklaşık 1,5 milyon hektar alanda tuzluluk ve alkalilik sorunu bulunmaktadır. Halofit bitkiler tuzlu topraklarda veya tuzlu sulama suyu kullanıldığında bile büyüme ve gelişme potansiyeline sahiptirler. Tuzlu topraklarda ekonomik tarım için, tuzlu alanlarda yetişebilen bitkilerin ürün desenlerine alınmaları, üreticiye ve ülkemize ekonomik yönden büyük yarar sağlayacaktır. Deniz börülcesi halofit olarak bilinen ve yüksek tuz koşullarında yaşayabilen bitkilerdendir. Bu çalışmanın amacı farklı kum-perlit karışım oranının ve tuz seviyesinin deniz börülcesinin büyüme ve gelişmesi üzerine etkisinin belirlenmesidir. Araştırma için 5 farklı kum-perlit karışım oranları (% 0, 25, 50, 75, 100) ve 4 farklı tuz (NaCl) seviyesi (0-200-400-600 mM) kullanılmıştır. Yaş ağırlıkları, gövde (sürgün) boyu, gövde çapı, nod uzunluğu, yan sürgün sayısı, kök uzunluğu belirlenerek, elde edilen verilerin varyans analizleri (ANOVA) üç tekerrürlü tesadüf parselleri deneme desenine göre değerlendirilmiştir. Araştırma sonuçları Sarcocornia perennis'in 600 mM tuz seviyesine kadar dayanıklı olduğunu, fakat 200 mM tuz seviyesinde optimum büyüme gösterdiğini ortaya koymuştur. 200 mM NaCl ve %100 perlit içeren yetiştirme ortamında S. perennis bitkisine ait en yüksek yaş ağırlıkları, gövde (sürgün) boyu, gövde çapı, nod uzunluğu, yan sürgün sayısı, kök uzunluğu değerleri elde edilmiştir. Elde edilen verilere göre, deniz börülcesi tarımında deniz suyunun, sulama suyu olarak kullanılabileceği ortaya çıkmıştır.
Salinity is one of the environmental stress factors that significantly limits the production of food products by endangering world' productive agriculture. Approximately 6% of the surface area of the world is faced with problems of soil salinity. Turkey has salinity and alkalinity problems in nearly 1.5 million hectares of its lands. The halophyte plants have the potential for growth and development even if the salty soil and salty irrigation water are used. For economic farming in saline soil, the production of plants grown in salty areas will provide high benefit to the producers and the economy of our country. Samphire is known as a halophyte plant that can survive in high salinity conditions. The main objective of this study sand-perlite mixture ratio and the salt level is to determine the impact on the growth and development of Sarcocornia. On different rate sand-perlite (0%, 25, 50, 75, 100) and four different salts (NaCl) level (0-200-400-600 mM) taken to experiment in the culture room. Fresh weight, stem height, stem diameter, nods length, number of lateral branches and root length were determined as a growth parameter in the plant. The data were subjected to analysis of variance (ANOVA) using factorial randomized complete plots designed with three replications. The research results revealed that tolerated salinity up to 600 mM NaCl; but the optimum growth was at 200mM NaCl. At 200 mM NaCl and 100% perlite growth medium, S. perennis plants were recorded the highest fresh weight (g/plant), the highest stem height, highest stem diameter, the tallest node, the highest number of lateral branches, and the tallest root. According to the data obtained, in the samphire cultivation has appeared that seawater can be used as irrigation water.
