Alex.0000-0003-1693-4775Journal Article20210127In this research, during the 2016 and 2017 summer seasons, two field experiments were performed at the Agricultural Experimental Station Farm (Abies region), Faculty of Agriculture, Alexandria University. The study investigated the possibility of lowering NPK levels to 75%, 50% and 25% below the recommended level for NPK fertilization; in addition to the recommended fertilizer level of NPK 100% as a control treatment, also, the application of a foliar spray of seaweed extract (SWC) at 0, 5, 10, and 15% concentrations, and their interaction between NPK fertilizer levels with various seaweed extract concentrations (SWC), on vegetative growth, yield and its components as well as on some chemical compositions characteristics of tuber roots. The results showed that the gradual increase in NPK fertilizer levels was accompanied by significant increases in the growth, yield and its components of sweet potato, as well as in the chemical composition of roots. In both growing seasons, the spraying of sweet potato with SWC at a concentration of 15 % resulted in a positive response to all characteristics. The application of NPK mineral fertilizer at 75% of the recommended, interacted with SWC at the concentration of 15%, was generally the most efficient treatment combination that gave the best sweet potato growth, yield and tuber root chemical compositions. In this respect, by using a foliar spray of 15 % SWC , the NPK fertilization can be decreased by 25 % without sacrificing the output value of the sweet potato concerning the amount and quality.https://sjas.journals.ekb.eg/article_158143_187b4aecb97bd0685daee8796fda6e05.pdfBeni-Suef University, Faculty of AgricultureScientific Journal of Agricultural Sciences2535-17963120210531Improving fenugreek plants growth and productivity via humic acid treatment152217346410.21608/sjas.2021.73626.1090ENMahmoudAbd ElhakemDepartment of Horticulture,Faculty of Agriculture, Minia University,EgyptEmadAhmedHort.

Humic acid (HA) at 0, 50, 100, 200, 300 and 400 ppm was applied as a seed priming, soil addition, foliar spray, seed priming + soil addition, soil addition + foliar spray. Both of HA concentrations and method of applications significantly improved plant growth and productivity. Moreover, there was a significant interaction between the two investigated factors. Plant height, plant dry weight, number of pods/plant and seed yield were generally increased by increasing HA concentrations regardless the method of applications. Soil addition had the highest significant values for all investigated traits regardless the concentration of HA. Overall, plants which treated with 400 ppm HA as soil addition and foliar spray had the highest significant number of pods/plant (257.77) and seed yield and (68.09 g/plant). Whereas, HA-untreated plants had the lowest values (71.27 pod/plant and 21.33 g/plant). Overall plant treated with 400 ppm HA as a soil addition and foliar spray had the highest yield 2587 kg/fad. however, control plants which developed from priming seeds had the lowest yield 746 kg/fad. Therefore, it is recommended to treated fenugreek plant with HA as a soil addition and foliar spry three times during the growth season to increase seed yield by about 3-fold compared with untreated plants.https://sjas.journals.ekb.eg/article_173464_65b5c17091cc17fa6a61b0e5a358e5e5.pdfBeni-Suef University, Faculty of AgricultureScientific Journal of Agricultural Sciences2535-17963120210531Studies the response of gladiolus plants to humic acid, potassium and water irrigation intervals.233717346510.21608/sjas.2021.73584.1089ENAmaniAdamAntoniadis Research Branch, Ornamental Plants Research and Landscape Gardening Res.

Accordingly, this study aimed to select some clones of garlic resistant to infestation with onion maggot through the implementation three cycles of clonal selection program within some improved garlic clones derived from Balady cultivar. Afterwards, the developed clones and their original population were evaluated in a randomized complete block design with three replicates. Thus, this study was conducted during four successive winter seasons of 2016/2017 to 2019/2020. The obtained results showed, clearly, significant differences among garlic selected clones, as well as their original population in their response to Delia antiqua M. and their bulb characteristics. Where, the selected clones varied between resistant and ability of infestation by onion maggot that was between 0.00% and 22.45%, with classification into five groups by cluster analysis: HR (highly resistant), R (resistant), MR (moderately resistant), MS (moderately susceptible) and S susceptible. Among the 16 selected clones three clones were HR; and six clones were R to onion maggot. Moreover, improvement percentage for the same character using clonal selection program was between 100% to 48.97%, which reflected that clonal selection could be an effective way to improve onion maggot resistance. Also, utilization of these improved clones will promise in minimize environmental pollution.https://sjas.journals.ekb.eg/article_173476_53975b6116e4fe0a6d4b955c0097e1f5.pdfBeni-Suef University, Faculty of AgricultureScientific Journal of Agricultural Sciences2535-17963120210531Effect of essential oils on vase life of cut flowers of Solidago canadensis L.

The five populations (P1, P2, F1, F2 and F3) of two crosses of bread wheat (Misr 3 x Shandaweel-1 and Giza 168 x Sakha 94) were evaluated in two locations during 2020/2021 growing season, at West West El-Minia and Sids Agricultural Research Station, Agricultural Research Center, Egypt, In order to determine the mode of gene action and the inheritance pattern of plant height, no. of spikes plant-1, no. of kernels spike-1, 100-kernel weight and grain yield plant-1. The t-test showed significant differences among parental genotypes of each cross for all studied characters. The mean effects (m) were highly significant for all characters under the study in the two crosses and locations, indicating the ability to enhance the performance of these characters by pedigree selection. Scaling test revealed the presence of nonallelic interactions (epistasis) in the most studied characters. Dominance gene effects were generally greater than additive ones in most characters. Gene effects varied among characters, whereas the dominance and duplicate dominance beside additive gene effects were found to play important role in the inheritance of most studied characters. The desired significant and highly significant positive heterotic effects to mid-parents for two crosses were detected in the two locations. Broad sense heritability estimates displayed moderate values in most characters. The highest expected genetic gain was found to be correlated with high heritability in narrow sense estimated in all studied characters.https://sjas.journals.ekb.eg/article_173602_f15562122e21d702158aedfdfe2783f1.pdfBeni-Suef University, Faculty of AgricultureScientific Journal of Agricultural Sciences2535-17963120210531Effect of Plant Growth Regulators on In Vitro Direct Organogenesis of Paulownia tomentosa plant11111817350110.21608/sjas.2021.71368.1084ENEngySeleemAgricultural Botany Department, Faculty of Agriculture, Cairo University, Giza, Egypt.Zeinab KassemTahaAgricultural Botany Department, Faculty of Agriculture, Cairo University, Giza, Egypt.Journal Article20210412In vitro propagation of P. tomentosa (Thunb.)

Bulked segregant analysis (BSA) was also used to identify simple sequence repeats (SSR) markers associated with the resistance to loose smut. The artificial inoculation was repeated twice through two successive seasons (2017/2018 and 2018/2019) under greenhouse conditions, and responses of tested genotypes against loose smut were evaluated in 2018/2019 and 2019/2020 seasons. Highly significant differences (<em>P</em><0.01) were observed for loose smut incidence among the tested RILs, indicating a considerable genetic variation. On average, loose smut incidence (LSI %) of the tested RILs ranged from 0% in RIL-64 to 97.5% in RIL-74 and RIL-93, with an average of 47.5%. Out of 100 RILs, the RIL-64 was considered as an immune genotype (no symptoms were observed on any plant), RIL-13, RIL-16, RIL-27 and RIL-37 were highly resistant (LSI= 5.0, 5.0, 2.5, 2.5%, respectively), and RIL-2, RIL-50 and RIL-96 were resistant to loose smut (LSI= 7.5, 7.5 and 10.0%, respectively), suggesting the usefulness of these genotypes for developing wheat varieties resistant to loose smut. BSA with forty two SSRs markers identified five positive alleles generated by Xgwm18-1B, Xgwm95-2A, Xgwm294-2A, Xgwm186-5A and Xgwm293-5A markers that were associated with loose smut resistance in the tested population, suggesting that several loci could be contributed to loose smut resistance in wheat.

These symptoms were suspected of being caused by Cucumber mosaic virus (CMV) and confirmed by indirect ELISA. Two samples obtained from wild tobacco and cucumber plants reacted positively with the CMV specific antiserum. Based on symptomology and disease severity on Nicotiana glutinosa and Chenopodium amaranticolor, two isolates of CMV were named CMV-wild tobacco (from Alexandria) and CMV-cucumber (from Kafr El-sheikh) and subjected to this study. Reaction of some diagnostic hosts of 11 plant species belonging to five families upon inoculation with the two isolates included different symptoms characteristic to CMV-infection, albeit those induced by CMV-wild tobacco being invariably more severe than those elicited by CMV-cucumber. Identification of virus isolates was confirmed using real time reverse transcription PCR (qRT-PCR). The test isolates demonstrated a single qRT-PCR amplification product of 500bp. The two isolates could be transmitted mechanically and easily transmitted by four aphid species in non-persistent manner. The most efficient vector was Myzus persicae followed by Aphis gossypii, Rhopalosiphum maidis and A. nerii with transmission rates of 90%, 70%, 60% and 50%, respectively, for CMV-wild tobacco and being 80%, 80%, 40% and 30%, respectively for CMV-cucumber.
