“…The first plant part interacts with salt is the roots and it is almost inevitable that the crops are affected by salt concentration. Therefore the results obtained in present study are in agrement with previous studies reporting increase on salt concentration negatively affects root and shoot development (Ashraf and Tufail, 1995;Dash and Panda, 2001;Delgado and Sanchez-Raya, 2007;Munns, 2002;Reinhardt and Rost, 1995). The reason that the root and shoot length are affected negatively by salt stress is due to toxic effect of salts as well as inhibition of cytokinesis and cell expansion.…”

“…Salinity negatively affects plant growth when salts accumulate in the root zone. High levels of salinity affect seed germination and plant growth by water deficit (osmotic stress), ion toxity and ion imbalance (ionic stress) or a combination of these factors (Läuchli and Grattan, 2007;McNeil et al, 1999;Reinhardt and Rost, 1995). The osmotic effect initially reduces the ability of the plant to absorb water.…”

In this study, the effects of different salinity levels (0, "control", 2, 4, 8, and 12 dS m -1 ) on seedling growth of Obez, RS 841 and Ferro F 1 pumpkin varieties, widely used around the world as rootstock, were investigated. Seedlings grown under saline conditions were investigated for plant main stem length, plant length, root length, shoot length, root fresh weight, root dry weight, shoot fresh weight, shoot dry weights and ion concentrations (Ca ++ , K + , Na + ) in the leaves of pumpkin varieties. The results revealed that root length, shoot length, root fresh weight, root dry weight, shoot fresh weight and shoot dry weights tend to decrease when the electrical conductivity of the solution is increased. Results indicated that these varieties responded different to some investigated parameters under saline conditions.

“…Reducing effects of salt stress on stem diameter (Pimmongkol et al 2002), epidermis cell width and length (Curtis and Lauchli 1987), cortex zone thickness (Casenave et al 1999), vascular bundle width (Pimmongkol et al 2002), xylem width (Baum et al 2000) and trachea diameter (Bass et al 1983, Reinhardt andRost 1995) were reported previously. Moreover, some researchers (Liphschitz andWaisel 1970, Shannon et al 1994) determined that salinity increased cuticle thickness and decreased cambium thickness.…”

“…The effect of salinity on root (Valenti et al 1991, Reinhardt and Rost 1995, An et al 2003 and leaf anatomy (Hu and Schmidhalter 2001) of plants had already been reported in previous works. Unfortunately, there are fewer studies on the effect of salinity on stems than on leaves and roots.…”

In this work, effects of gibberellic acid, 2-chloroethylphosphonic acid (ethephon), triacontanol, 24-epibrassinolide and polyamine (cadaverine, putrescine, spermidine, spermine) pretreatments on the stem anatomy of radish seedlings grown under saline conditions were studied. Salt stress decreased the stem diameter, epidermis cell size, cortex zone thickness, vascular bundle width, cambium thickness, xylem width, trachea diameter and phloem width in the seedlings non-pretreated with the growth regulators, in comparison with the control seedlings grown in distilled water medium. In addition, it slightly increased the cuticle thickness. On the other hand, many of the growth regulator pretreatments more or less stimulated the stem diameter, epidermis cell width, cortex zone thickness, vascular bundle width, xylem width, trachea diameter and phloem width in comparison with the control seedlings grown on saline medium. Moreover, they generally reduced the cuticle thickness, epidermis cell length and cambium thickness.

“…In addition fluoranthene exposure triggers changes in the cell morphology of other organs and tissues including the root tip, root cap, apical meristem and elongation zone (Kummerova et al, 2013). Similar abnormal development patterns of xylem have been also described in cotton grown in presence of high salinity (Reinhardt and Rost, 1995). Thus the xylem tissue seems to be particularly sensitive to external abiotic pollutant.…”

Abstract. Exposure to persistent organic hydrocarbon pollutants can have deleterious effects on the growth, physiology and anatomy of plants. Sand collected at an oil-drilling quagmire in southern Algeria was analyzed by GC-FID and found to contain 18mg.Kg -1 hydrocarbons. Pisum sativum L. (pea) plants were grown in laboratory conditions in sandy soil from the site. Plants growing in hydrocarbon polluted sandy soil had shorter primary roots and fewer lateral roots than control plants growing in non-polluted sandy soil. However lateral root dry weight was 35% higher than control. Pollutant-induced oxidative stress on pea roots resulted in lipid peroxidation and accumulation of MDA, H 2 O 2 and O 2 -in root tips. Enzymatic detox activities of superoxide dismutase and peroxidase were also over 40% higher in plants growing on polluted soil than in controls. The anatomy of pea roots was also affected by hydrocarbonpolluted soil, because xylem vessel differentiation was delayed and an unusual supplementary cell layer was formed in the endoderm. These data suggest pea plants adapt morphologically and anatomically to polluted soil.
