T WENTY species that belong to 13 genera under six families, two belonging to order Asparagales and four to order Liliales, are subjected in this recent work. Micro-morphological leaf characters using both Light and Scanning Electron microscopes have been studied. The pavement cells, hairs, prickles and stomatal characters beside stomatal density and index have been calculated. The data obtained has been subjected to clustering analyses using Paleontological Statistics (PAST) program. The results which were obtained from this study do not give clear separations between the two orders or even the families and considered the studied six families have common leaf characters. Meanwhile, characters of epidermal cells, hairs, papillae, prickles, and stomata can give clear features in the identification of some species. Hence, we can conclude that the separation of these orders and families and their taxonomic ranking need further investigation to clarify the perfect relation between them.

I N THIS work, cultivated pea ( Pisum sativum L. cv. Master B) is used as a legume model crop plant to investigate the effect of abscisic acid (ABA) treatment on seed filling during embryogenesis. This was evaluated by using two exogenously applied concentrations (10& 20 µM) during three stages of seed developments (early, intermediate and late). Phenotypic characterization of the treated plants included measurement of seed / legume length and diameter at full maturation stages after treatment. The expression of major proteins of the treated plants was detected using SDS-PAGE electrophoresis technique. Our data showed a positive effect of ABA when applied at the late stage of seed development. ABA significantly increased legume size and elevated the expression of some major proteins such as convicilin (70-75kDa), vicilin (50, 34kDa) and legumin (40kDa). The impact of these results is further discussed.

T HE NILE Delta is one of the oldest and largest deltas in the world covers 4 % of Egypt’s area and occupies 63 % of the Egyptian cultivated land. The present study focuses on the goods and services offered by Delta’s natural ecosystem. Thirty field trips were conducted to different locations to cover the study area from spring 2020 to summer 2022. Based on field observation and information gathered from residents and herbalists (60 people from the study area were interviewed, ranging in age from 30 to 60 years old) the goods, services and threats of the recorded species were assessed. Forty-nine were recorded and their roles in goods and services; identified threats that cover the gradual change in the study area were recorded. Recorded species offer many goods such as grazing (36 species), medicinal (26) and human food (15). Also, they provide environmental benefits that ruderal and segetal weeds are the most commonly offered service, followed by bank retainer (16 species) and weed controller (6 species). Thirty-six species (73% of recorded species) suffer from at least one type of threat; over-collecting and over-cutting were the most common threat (46.9%), then habitat loss (40.8%), browsing and over-grazing (34.7%), clearance for agriculture (24.5%) species) and disturbance by cars or trampling (10%). Authors recommended that Nile Delta natural flora need continuous monitoring and conservation, as this region faces deteriorating habitat loss and even extinction of plants; which offer many goods and services for humans and the environment.

O NE of the major factors significantly modifying plant physiology and ultimately causing a loss in crop productivity is water deficiency stress. Plant-based pigments are highly effective in enhancing growth and reducing the consequences of water stress. The present study aimed to identify the effects of copper chlorophyllin (Cu-Chl) at rates of 0, 1, and 2% on the growth, yield, and physiological traits of spinach plants of the variety Viroflay grown under three irrigation levels of 100%, 75%, and 50% crop evapotranspiration rates (ETc) in the 2020 and 2021 growing seasons. In comparison with full irrigation (100% ETc), deficit irrigation with 50% ETc drastically reduced plant growth parameters (height, leaf number, leaf area, and fresh and dry weight), yield, relative water content (RWC), leaf membrane stability index (MSI), electrolyte leakage (EL), chlorophyll a, chlorophyll b, carotenoids, Fe, and Cu content. However, the nitrate and oxalate content increased in the plants. All studied values were significantly higher except nitrate and oxalate content which were lower with Cu-Chl application, in comparison with those without Cu-Chl application. The present work demonstrated that the adverse effects of water deficit on growth, yield, plant water status, and photosynthetic pigments of spinach plants could be alleviated when using Cu-Chl application.
