چکیده

We investigated the effect of wheat germ agglutinin (WGA) on plant resistance to salinity. We showed that treatment of wheat seedlings with exogenous WGA resulted in an increase in cell division and elongation. Incubation of 4-d-old seedlings in 2% NaCl solution for 24 h resulted in appreciable decrease in mitotic activity of meristem cells in roots and growth of whole seedlings. At the same time, pretreatment of seedlings with WGA during 24 h completely removed the detrimental effect of salinity on these parameters. Moreover, the treatment of seedlings, subjected to short-term (7 h) salt stress, with WGA for 24 h resulted in restoration of mitotic activity of root cells while the control plants did not restore. These data show the defense effect of WGA on growth processes of wheat plants.

Seed Priming With Plant Growth-Promoting Rhizobacteria Alleviate Salinity Stress In Wheat Plant

The objective of this paper was to study the effects of two strains of isolated plant growth-promoting rhizobacteria (PGPR) on physiological and biochemical changes of wheat leaves under salinity conditions. The sterilized seeds were soaked in distilled water (control) and Nutrient Broth liquid medium of Enterobacter cloacae and Bacillus cereus (inoculated treatment) for 2 hours. After 10 days ...

Salicylic Acid Prevents the Damaging Action of Stress Factors on Wheat Plants

We investigated the effect of salicylic acid (SA) on plant resistance to environmental stress factors. Treatment of wheat plants with 0.05 mM SA increased the level of cell division within the apical meristem of seedling roots which caused an increase in plant growth. Phytohormones are known to play a key role in plant growth regulation. It was found that the SA treatment caused accumulation of...

Kinematic Analysis of Leaf Growth in Grasses: A Comment on Spatial and Temporal Quantitative Analysis of Cell Division and Elongation Rate in Growing Wheat Leaves under Saline Conditions, by Yuncai Hu and Urs Schmidhalter in JIPB

Hu and Schmidhalter (2008) conducted a study with wheat seedlings growing in saline and non-stressed (control) conditions with the aim of identifying and quantifying the cellular basis for the reduction in leaf growth. We applaud their goals as salinity is an important issue for plant ecology and food production; however, we have concerns about the methodology used and the subsequent conclusion...
