The soils of the plant taxa were medium textured, sand or sandy-loam, saltless or a little salty, neutral, limy, rich in potassium and with very little phosphorous, and with medium levels of nitrogen and organic matter. G. antari, which had the greatest lime content, had the lowest number of leaves. G. muralis and G. tubulosa had the lowest saturation values and lime content but the greatest number of leaves. | Turkish Journal of Botany Turk J Bot (2013) 37: 85-98 © TÜBİTAK doi: Research Article Soil-plant relations in the annual Gypsophila (Caryopyhllaceae) taxa of Turkey 1, 2 Mustafa KORKMAZ *, Hasan ÖZÇELİK Department of Biology, Science and Arts Faculty, Erzincan University, 24100 Erzincan, Turkey 2 Department of Biology, Science and Arts Faculty, Süleyman Demirel University, 32260 Isparta, Turkey 1 Received: Accepted: Published Online: Printed: Abstract: The soil properties of the annual Gypsophila L. taxa of Turkey and their effects on plant morphology were investigated. The taxa studied were Gypsophila heteropoda Freyn & Sint., G. parva Barkoudah, G. elegans ., G. bitlisensis Barkoudah, G. viscosa Murray, G. antari Post & Beauverd, G. muralis L., G. tubulosa (Jaub. & Spach) Boiss., G. confertifolia ., and G. pilosa Hudson. The soils of the plant taxa were medium textured, sand or sandy-loam, saltless or a little salty, neutral, limy, rich in potassium and with very little phosphorous, and with medium levels of nitrogen and organic matter. G. antari, which had the greatest lime content, had the lowest number of leaves. G. muralis and G. tubulosa had the lowest saturation values and lime content but the greatest number of leaves. If the lime content increased, the development of roots decreased, and when the rate of sand increased, the development of roots increased. For G. muralis, phosphorus concentration, seed size, and salt content were negatively related to number of leaves. For G. tubulosa and G. antari, potassium and organic matter concentrations were negatively related to number of leaves. In G. muralis, salt content was positively related to calyx diameter and seed size. In G. confertifolia, organic matter content was positively correlated with height of the calyx, petal, and bract. It was observed that G. pilosa, G. bitlisensis, and
