“…Jaleel et al (2007) stated that salinity could be an inhibition of root development by altering the external water potential and increasing ion toxicity and instability in plants. As it can be seen in Tables 3 and 4 of this study, 50, 150 and 200 mM doses of NaCl were importantly hazardous to the root development of durum wheat plantlets statistically.…”

The effect of salt stress (NaCl) on shoot height (cm), root length (cm), dry and fresh weight (g), chlorophyll a and b, total chlorophyll (mg -1 ) and carotenoid amount was investigated in this study. In addition, the positive effects of Ca +2 (20 mM) were also investigated. Triticum durum Desf. Mirzabey, Kunduru-1149, and DH-6 and DH-8, derived from Kunduru-1149 using wide hybridization, were used as plant materials in this study. Arnon-Hoagland solution was used as food source for the plants and various NaCl concentrations (0, 50, 150 and 200 mM) and Ca +2 (as CaCl 2 ) were added to Arnon-Hoagland solution. The research was completed at the end of the fifth week and the effect of NaCl on the root length of genotypes was found to be significant (P<0.05). Ca +2 caused an increase in root length in all NaCl applications, except for the 200 mM NaCl, whereas shoot height decreased with increasing salt concentration, except for the 50 mM NaCl. This character also increased with Ca +2 application significantly. Dry and fresh weight of the plant decreased with increasing salt concentration. Ca +2 ameliorated dry and fresh weight of the plant at 50 mM NaCl in all the genoypes and NaCl doses, except for the Kunduru-1149 and DH-6. The highest increase in total chlorophyll amount was found in 50 mM NaCl + CaCl 2 in DH-8 (from 17.29 to 20.14 mg g -1 ). However, the rate of increase in the amount of carotenoid by the addition of Ca +2 was also determined for each genotype.

“…At such stage, plants are more sensitive to environmental stresses that may lead to injuries and, under extreme conditions, plant death (Ditommaso, 2004;Jaleel et al, 2007). Furthermore, according to El Rabey et al (2015), a high salinity affects the whole plant and may lead to water deficit stress, metabolic toxicity, nutritional deficiencies and, finally, a drastic yield reduction.…”

Desiccation-sensitive seeds lose water quickly, what is an important feature to determine their ability to tolerate periods of seasonal drought. Furthermore, excess of soluble salts on seed germination causes a reduction in the substrate water potential. The objective of this study was to assess the desiccation and salinity tolerance of seeds of four ornamental palm species. Different moisture contents were studied for seeds of Carpentaria acuminata, Dypsis decaryi, Phoenix canariensis, and Ptychosperma elegans, while five concentrations of NaCl were tested separately for C. acuminata and P. elegans. Seeds of C. acuminata and P. canariensis tolerated drying at 5% and 8% seed moisture, respectively. On the other hand, seeds of D. decaryi and P. elegans were sensitive to dehydration even at high moisture contents, 20% and 27% of seed moisture, respectively. Increase on salt concentration did not affect germination or germination rate of C. acuminata and P. elegans seeds.

“…Plant reactions exist to circumvent the potentially harmful effects caused by a wide range of both abiotic and biotic stresses, including light, drought, salinity and high temperatures (Chaves et al, 2002;Jaleel et al, 2008aJaleel et al, , 2008bJaleel et al, , 2008c. Drought is a major abiotic constraint limiting the chickpea yield up to a greater level.…”

In the present study pot culture experiment was conducted to estimate the ameliorating effect of triazoles, namely triadimefon (TDM), paclobutrazol (PBZ) and hexaconazole (HEX) on drought stress, pigment composition and biochemical constituents of Zea mays L. (Maize) belongs to the family poaceae. From 30 days after sowing (DAS), the plants were subjected to 4 days interval drought (DID) stress and drought stress with TDM at 15 mg l −1 , PBZ at 15 mg l −1 and HEX at 10 mg l −1 and one day interval irrigation was kept as control. The plant samples were collected on 40, 50 and 60 DAS, and separated into root, stem and leaf for estimating the photosynthetic pigments and biochemical constituents. Drought and drought with Triazole compounds treatment increased biochemical constituents like amino acid (AA), proline (PRO) content, whereas decreased the pigment contents like chlorophyll and carotenoid when compared to control. The triazole treatment mitigated the adverse effects of drought stress by increasing the biochemical potentials and thereby paved the way for overcoming drought stress in maize plants.
