“…These families are among the most common families in Mediterranean North African flora [75]. In addition, these plant families were the most frequent in many ecological studies dealing with the floristic composition of different regions in Egypt, such as [76], [77], [78], [79], [80] and [81] .…”

Euphorbia peplus (Family Euphorbiaceae) is a medicinal annual weed found in many habitats in Egypt. The main goal of this study was to assess the diversity of E. peplus accessions growing in Egypt and to measure the levels of genetic characters of six selected accessions collected from different habitats in Egypt, by using Inter-Simple Sequence Repeat (ISSR), SDS-PAGE, and isozymes. Extracting, measuring, and identifying the bioactive compounds were also taken in our consideration. A total of 45 plant species were recorded as associates with E. peplus in various habitats. Poaceae and Asteraceae were the most common plant families. Therophytes were the most abundant life forms. Cosmopolitan species were the most common floristic category. Cynodon dactylon, E. peplus, and Sisymbrium irio had the highest importance values, of 58.3, 47.6, and 46.8, respectively. A total of six primers were evaluated for ISSR-PCR analysis, and the polymorphism percentages varied from 20-66.66%. Primer HB-9 produced the maximum number of polymorphic products (four bands), while primer HB-12 produced the lowest number of polymorphic products (one band). SDS-PAGE analysis revealed some variations among the studied accessions in the banding pattern and 50 % polymorphism. Two isozymes (peroxidase and polyphenol oxidase) were used to distinguish among the six accessions of E. peplus. The obtained data showed genetic and phytochemical compounds content variation among the six studied samples.

“…Several studies have investigated the effects of agricultural practices on the biotic and abiotic components of agroecosystems and consequently on the weed flora. Weed composition in response to these changes has also changed in adaptation to these new conditions [35]. They also mentioned that more resistive species may have replaced sensitive weeds in response to the excessive use of chemicals and the inappropriate methods implemented to eliminate weeds.…”

Sharkia Governorate was the subject of a floristic survey and phytogeographical investigation. In the 169 sectors, 124 species belonging to 80 genera and 29 families were recorded. Twenty five percent of the recorded family belonged to Poaceae (Gramineae). According to these findings, therophytes, which comprised 87 species and accounted for 70.61% of the recorded species, were the dominant life form. Additionally, chorology showed that the monoregional area, where these elements make up cosmopolitan species accounted for 31 species in total (25% of all species). In this investigation, 84 new species that had not been recorded before in the same area were illustrated.

“…Several studies investigated the weed flora of some agroecosystems in many countries as in Chine (36). As well as in Egypt, El-Saied et al, El-Saied and Bedair (34,32), studied the weed flora in a different area of Egypt. Soliman et al, (58), studied the flora and weed-crop interaction in Egypt.…”

This study was aimed to investigate weeds kind in palm plantations. Date palm is the most chief economic crop in most countries of the Arabian Peninsula. Many factors, such as the presence of weeds, may cause a huge loss in the production of dates. Despite the severe damage caused by the presence of some weeds in agroecosystems, many weeds have many medicinal and economic uses. A total of 62 species were listed in palm Plantations in Tabuk and Al-Qassim Regions. A total of 51 species were listed in Tabuk Region (The number of unique species in the Tabuk Region reached 32 that not recorded in Al-Qassim Region. Also, 19 species were recorded in both of Tabuk and Al-Qassim Regions). A total of 30 weeds were listed in Al-Qassim Region (The number of unique species in the Al-Qassim Region reached 11 that not recorded in the Tabuk Region. In addition to, 19 species were recorded in both of Tabuk and Al-Qassim Regions). Zygophyllaceae was the most common family, the majority life span was annuals and the most common life form was therophyte in both Tabuk and Al-Qassim Regions. Data management and classification were achieved using PCORD (TWINSPAN and DCA analyses).
