Salt tolerance classification of crops according to soil salinity and to water stress day index

Effects of Different Irrigation Strategies on Soil Water, Salt, and Nitrate Nitrogen Transport

“…The most widespread crop in our study site is sunflower, which is defined as moderate salt tolerance sensitive crop [25]. Based on the researches for sunflower growth characteristic in our study site [26], the threshold value of soil salt content for sunflower's root zone (0-40 cm depth) was around 0.3% (168 mg·cm -2 ).…”

Growth and Uptake of Sodium and Potassium in Broad Bean (Vicia fabaL.) under Salinity Stress

“…The available studies also record decreases in chlorophyll content, number and length of internodes and nodes, and, related to this, number of flowers and reduction in weight of plant organs such as leaves, shoots, and roots. The development of roots has been decreased, and inhibition of lateral root development also occurred (Parida, Das, and Mittra 2004;Kaya et al 2003;Singh et al 2003;Ramoliya and Pandey 2002;Sairam, Rao, and Srivastava 2002;Bolarin et al 2001;Katerji et al 2000;Carvajal et al 1998;Rodriguez et al 2005;Turan et al 2009). However, not all of our results were consistent with the existing literature.…”

“…(4) Inhibition of water transportation to the stem because of reduction of water-transport capacity of the roots. (5) Decrease in synthesis of DNA, RNA, and protein, increase of ABA, followed by decreasing of gibberellic acid and cytokinin (Lorenzen, Aberle, and Plieth 2004;Kaya et al 2003;Adiku et al 2001;Katerji et al 2000;Khan, Ungar, and Showalter 2000;Rodriguez et al 1997;Marschner 1995;Botella, Cerda, and Lips 1994;Kuchenbuch, Claassen, and Jungk 1986;Kafkafi, Valoras, and Letey 1982;Tal 1977;Helal, Koach, and Mengel 1975).…”

“…The available literature records that salt stress in various plants leads to reductions in growth parameters such as inhibition of plant height; reduction in number of leaves; inhibition of leaf extension and development (assimilation surface); thinner epidermal and mesophyll layers in leaves; decreased rate of CO 2 uptake; difficulties of stomatal regulation; reduction of transpiration rate, chlorophyll content, and cell division and development; reduction of internode numbers and internodal length; reduction of dry weights of plant organs, leaves, stems, and roots; and inhibition of lateral roots (Parida, Das, and Mittra 2004;Kaya, Erol, and David 2003;Singh et al 2003;Ramoliya and Pandey 2002;Sairam, Rao, and Srivastava 2002;Bolarin et al 2001;Katerji et al 2000;Carvajal et al 1998;Rodriguez et al 1997;Katerji et al 1994;Matsuda and Riazi 1981;Rizk and Normand 1969).…”

“…While in Turkey 47,000 tonnes of dry broad bean has been produced, total world production is up to 4 438 510 tonnes (Anonymous 2005). The broad bean (Vicia faba L.) is a member of the Leguminosae family (Fabaceae) whose growth shows mild sensitivity to salt stress (Katerji et al 2000). Since there appears to have been no study on ion uptake by this plant species, grown in perlite under controlled greenhouse conditions, the following investigation has been carried out on two selected cultivars grown in perlite-filled pots.…”
