Phosphorous Uptake of Gourds Species and Watermelon under Different Salt Stress

Veli Uygur and Halit Yetisir

Abstract:
Phosphorous uptake of 7 different gourd genotypes [Cucurbita maxima, C. moschata, Luffa cylindrica, Benincasa hispida, Lagenaria siceraria landraces (SKP and BR) and Lagenaria siceraria hybrid (FRGold)] and a watermelon [Citrullus lanatus (Thunb.) Matsum and Nakai] cultivar Crimson Tide grown under five different saline conditions for 30 days was investigated. Salinity stress was induced by continuous irrigation with saline water having EC of 0.5, 4, 8, 12 and 16 dS m-1. P uptake was affected by plant species and salinity levels. Salinity stress has resulted in an increase in P content of gourd leaves. For example, P content of BR at 16 dS m-1 was three times higher than that of control (0.5 dS m-1) whereas salt resistant genotypes such as C. moshata and maxima showed little increase. Results showed that smaller change in P content could be an indication of stronger resistance to salinity stress, since excessive P uptake under salinity stress may cause P toxicity.
