Anatomical Alteration in Response to Irrigation and Water Stress in Some Legume Crops

Abstract

Anatomical alteration of leaf tissues components were investigated in regards to adequate and inadequate watering in Mungbean, Vetch and three Lentil cultivars namely Baraka, Adlib and Nineveh. The possibility of mitigating the alteration of these adversities by the aid of GA 3 was also investigated. Lentil plants irrigated by 50% level appeared to be the most effective treatment. This treatment manifested the best results as it exceeded that of 75% level in terms of cuticle thickness (69.3%), epidermis thickness (12%), and spongy layer thickness (7%). Moreover, it also exceeded that of 25% level in epidermis thickness (22.6%), palisade thickness (2.8%), spongy layer thickness (21%), and thickness of lower epidermis (4.5%). Irrigation level of 75% exceeded that of 25% level in epidermis thickness (9.4%), palisade thickness (3.1%), spongy layer thickness (13.1%), and thickness of lower epidermis (13%). Common Vetch irrigated by 25% level was the paramount treatment. It exceeded that of 50% irrigation level in terms of cuticle thickness, epidermis thickness, palisade thickness, spongy layer thickness, thickness of lower epidermis, and thickness of lower epidermis cuticle by 54.9, 12, 13.3, 37.1, 37.9, and 71.9%, respectively. Mungbean irrigated every 2 days exceeded that of Mungbean irrigated every 8 days in cuticle thickness (42.9%), epidermis thickness (22.2%), thickness of lower epidermis (5.1%), and thickness of lower epidermis cuticle (25%). 200 mgl -1 GA 3 Common Vetch treated plants exceeded that of untreated in term of stomata aperture length (22.4%), and stomata population (29.9%). Mungbean irrigated results every six days and sprayed with 200 mgl -1 GA 3 gave the highest stomata length (5.4 µm). Finally Baraka lentil cultivar revealed significant increases in stomata aperture 5.6% and 6.7%, as compared to Nineveh and Adlib, respectively. Baraka was also superior over Adlib stomata length (4%).

Effect of nanoparticle on growth, biochemical and anatomical characteristics of moringa plant (Moringa oleifera L.) under salinity stress condition

“…In general, the above mentioned results clearly indicate that salinity stress level of irrigation water had opposite effect on those leaflet anatomical characteristics of Moringa oleifera L. plant. The obtained results are in harmony with those reported by Child et al (2003), Abdel and Al-Rawi (2011) and El-Afry et al (2012).…”

Adaptive components of tolerance to salinity in a saline desert grass Lasiurus scindicus Henrard

“…3). This was further supported by increased trichome density on leaf margins (Abdel and Al-Rawi 2011). Lasiurus scindicus is a salt excretory grass, which is capable of excreting excess of toxic ions.…”

Exogenously applied glycinebetaine induced alteration in some key physio-biochemical attributes and plant anatomical features in water stressed oat (Avena sativa L.) plants

“…Similar results were observed in the present study that drought stress increased leaf bulliform cell area and abaxial epidermis thickness by the exogenously applied GB in both oat cultivars. In view of an earlier report, increase in leaf thickness under drought stress could be due to parenchymatous cells, which are the most important storing cells of leaf, and therefore, are chiefly important under water deficit environments (Abdel and Al-Rawi, 2011).…”
