Abstract

The present study was conducted to investigate the effects of different irrigation water salinity levels [prepared as to have final Sodium Absorption Ratio (SAR) of below 3 with different salt sources (NaCO3, MgCl2, CaCl2) and different electrical conductivity (ECi) values (0, 4, 8, 12, 16, 20, 30, 40 dS] on germination of different guar lines mainly used as feed and food (125-1, 1-1, 40-1, 57-1, 62-4, 94, 98, 114 ), / m) under laboratory conditions. According to the results of the variance analysis, it was determined that the irrigation water salinity on the germination rate and germination power of guar seeds were statistically significant (p <0.05). As the salinity of the irrigation water increased, the germination rate and germination efficiency decreased. When the germination rate is considered, germination occurs at the recommended level (80%) by the World Seed Association at the application level of 8 dS m-1. It has been determined that germination power is affected from 12 dS m-1 application. In genotypes, the germination rate and germination power were generally close to each other while the lowest rates were determined in genotypes 1 and 2. Within the scope of the study, the influence of increasing salinity of the irrigation water was determined for all parameters examined.

Özet

Araştırma, 8 adet sakız fasulyesi (125-1, 1-1, 40-1, 57-1, 62-4, 94, 98, 114) hattında, SAR değeri 3’den küçük olacak şekilde farklı tuz kaynaklarından (NaCO3, MgCl2, CaCl2), farklı seviyelerde sulama suyu elektriksel iletkenlik (ECi) değerlerine (0, 4, 8, 12, 16, 20, 30, 40 dS m-1) sahip sulama sularının çimlenme üzerine etkilerini belirlemek amacıyla laboratuvar koşullarında yürütülmüştür. Yapılan varyans analizleri sonucuna göre, sakız fasulyesi tohumlarının çimlenme hızı ve çimlenme gücü üzerine sulama suyu tuzluluğunun istatistiki açıdan önemli (p< 0.05) etkileri olduğu belirlenmiştir. Sulama suyu tuzluluğu arttıkça çimlenme hızı ve çimlenme gücü azalma göstermiştir. Çimlenme hızı dikkate alındığında 8 dS m-1’lik uygulama seviyesinde, Dünya Tohumcular Birliği tarafından önerilen oranda (%80) çimlenme meydana gelmektedir. Çimlenme gücünde ise 12 dS m-1 uygulamasından itibaren etkilenmenin olduğu belirlenmiştir. Genotipler de ise çimlenme hızı ve çimlenme gücü açısından genel olarak birbirine yakın oranlar belirlenirken en düşük oranlar 1 ve 2 nolu genotiplerde belirlenmiştir. Çalışma kapsamında, artan sulama suyu tuzluluk seviyesine bağlı olarak incelenen tüm parametrelerde etkilenme belirlenmiştir.
