Farklı Puccinellia ciliata Popülasyonlarının Tuzluluk Stresine Fizyolojik ve Tohum Verimi Tepkileri

Öz

Puccinellia ciliata B.’nın PSII (Fv/Fm)'nin maksimum fotokimyasal etkinliği, SPAD değeri ve stomatal iletkenlik gibi bazı fizyolojik özellikleri ve tohum verimi ve verim komponentleri üzerinde tuzluluğun etkisi araştırılmıştır. Bu amaçla 7 populasyon tuzluluk stresine maruz bırakılmıştır. Tuz uygulamaları, bitkiler ~ 4 haftalık iken başlamış ve denemenin sonuna kadar devam etmiştir. Fideler 30 g/l NaCl çözeltisi ile sulanmıştır. Bitkilerdeki fizyolojik gözlemler, gövde uzama döneminde gerçekleştirilmiştir. Popülasyonların tuzluluğa tepkisi Fv/Fm ve stoma iletkenliği için önemli farklılıklar gösterirken SPAD değerleri etkilenmemiştir. III numaralı populasyon tuzlu koşullarda daha uzun bitki boyu, salkım başına daha fazla tane sayısı ve daha fazla başakçık sayısı ve tane verimi vermiştir. Bu nedenle, puccinellia yetiştiriciliğinde ana ebeveyn olarak kullanılması önerilmektedir.

Physiologic and Seed Yield Responses of Different Alkali Grass (Puccinellia ciliata) Populations to Salinity Stress

Öz

It was investigated the effects of salinity on some physiological characters such as maximal photochemical efficiency of PSII (Fv/Fm), SPAD value and stomatal conductance and seed yield and yield components in Puccinellia ciliata B. For this purpose, 7 populations were subjected to salinity stress. Salinity applications to plants started when plants were at the ~4 week old, and continued until the end of the experiment. Seedlings were watered with 30 g/l NaCl solution. Physiological observations in plants were carried out at stem elongation stage. The response of populations to salinity shown significant differences for Fv/Fm and stomatal conductance, whereas SPAD values not affected. Population III exhibited longer plant height, higher number of grains per panicle, spikelet number per panicle, grain yield per plant in salinity conditions. Therefore, it was suggested to be used as a female parent in puccinellia breeding.
