So, in the 2016/2017 and 2017/2018 seasons a field experiment was carried out on a private orchard in Kafr El-Sheik governorate, Egypt. Trees were treated with Benzyladenin (BA) at 50ppm, Sytofix (CPPU) at 10ppm, GA3 at 50ppm, and GA3 combined with BA or CPPU. Plant growth regulators (PGRs) were applied three times after the full bloom stage by 15, 30 and 45 days as foliar application. Results revealed that PGRs increased quality parameters, productivity, and chlorophyll content, as well as reduced fruit splitting % and carotene content. GA3 plus CPPU gave the highest fruit fresh weight, fruit length, fruit yield, and SSC%. However, GA3+BA registered the greatest fruit diameter, chlorophyll content, TA%, vitamin C, as well as decreased fruit splitting % and carotene content. Regarding the marketing period, GA3 plus BA obtained the highest reduction % in weight loss, decayed fruit percentage, however, recorded the greatest vitamin C and chlorophyll contents. ABA results clarified that application of PGRs tended to decrease significantly its content in peel fruit, in particular, GA3 alone or combined with BA showed the lowest content of ABA in both seasons. These results will not only help researchers to understand the roles of PGRs in navel orange fruit growth, development, and productivity but can also be applied to large-scale fruit production and prolong the marketing period.https://ejoh.journals.ekb.eg/article_160138_a7e76e4d390340805aa0f718e8e1761b.pdfNational Information and Documentation Center (NIDOC), Academy of Scientific Research and Technology (ASRT)Egyptian Journal of Horticulture1110-020648220210801Influence of Leaf/ Bunch Ratio on Yield and Fruit Quality of “Zaghloul” Dates15716317058110.21608/ejoh.2021.63533.1165ENMohamed MahmoudIbrahimHort.

Three levels of leaf/bunch ratios at 6:1, 8:1, and 10:1 plus the control treatment (only dead leaves were cut) were investigated. The tested physical characteristics were yield, weight of bunch, fruit and fruit flesh, as well as fruit length and diameter, and dry weight of flesh of date fruits. In addition, the total soluble solids content and Tannins as chemical characteristics of date fruits were measured. All pruning treatments increased the yield/palm in comparison with the control. The leaf/bunch ratio at 10:1 achieved the highest yield (182.06 and184.50 kg/palm) in the two seasons, respectively. The palm yield of check treatment was lower with results of 135.22 and 136.00 kg/palm in the studied seasons, respectively. Palms in all levels of leaf/bunch ratios recorded the highest of the bunch weight and fruit weight of dates in comparison with those in palms had no pruning. Generally, all applied leaf/bunch ratios had a positive effect on other measured physical properties of ‘Zaghloul’ date palm fruits. The total soluble solids content was higher in pruned palms, however, the tannins percentage was lower in the same palms. The leaf/bunch 10:1 ratio gave the best results regarding the tested characteristics of ‘Zaghloul’ date palms under the studied region.<br /><br />https://ejoh.journals.ekb.eg/article_170581_56ace904a1492ef8f28376e00471d7f7.pdfNational Information and Documentation Center (NIDOC), Academy of Scientific Research and Technology (ASRT)Egyptian Journal of Horticulture1110-020648220210801Efficiency of Potassium Solubilizing Bacteria Inoculants to Improve Yield of Carrot and Their Potential Cytotoxicity on Root Tip Cells16518017162010.21608/ejoh.2021.67147.1168ENHassan AhmedSoltanCentral lab. of organic agriculture, Agriculture research center, Giza, EgyptSayedOsmanGenetics Department, Faculty of agriculture, Minia universityJournal Article20210313Studying the ability of potassium solubilizing bacteria (KSB) inoculants to partially replace the convential potassium mineral fertilizer (KMF) in carrot fertilizing program, in addition to, clarifying their potential cytotoxicity on mitotic chromosomes division of carrot were conducted in the present investigation. According to field and laboratory experiment results, using the potassium solubilizing bacteria (KSB) as biofertilizer positively affected yield and quality of carrot especially, KSB3 inoculate. On the same direction, KSB and KMF combinations were more efficient than those of KSB and KMF alone. Regarding to the cytotoxic studies, data reveled that carrot root tips treated with KSB and their combinations improved cell division and exhibited low cytotoxicity on mitotic division than those treated with KMF alone. So, it could be concluded that potassium solubilizing bacteria (KSB) inoculants could be used alone or mixed with low doses of KMF as alternative of potassium mineral fertilizer (KMF) in carrot fertilizing programs. In addition, it had less cytotoxicity and ecologically safer than KMF.<br /><br />https://ejoh.journals.ekb.eg/article_171620_46257d627b960a7c8016222b346c7ed8.pdfNational Information and Documentation Center (NIDOC), Academy of Scientific Research and Technology (ASRT)Egyptian Journal of Horticulture1110-020648220210801The Effect of Grafting on Squash Plants Grown Under Low Plastic Tunnel in Winter Season18119217236510.21608/ejoh.2021.60786.1164ENYasmineAbd ElmohsenVegetable Research Dept., National Research Center, Cairo, Egypt.S.

The chosen plants are radish (Raphanus sativus), rocket (Eruca sativa) and turnip (Brassica rapifera.). The treated plants were exposed separately to cadmium levels of 5, 25 and 50 ppm, and salinity levels of 1000, 1500 and 3000 ppm, through irrigation, in addition to the control treatments (0 ppm Cd or salinity). <br /> Cadmium stress on the three vegetable plants caused clear reduction in plant height, root length, biomass, chlorophyll pigments and overall growth parameters over time. Radish, rocket and turnip plants were found to accumulate Cd in their leaves when exposed to different Cd concentrations. Accumulated Cd was increased in leaves tissue with the increase of Cd concentration level. A general decrease in chlorophyll, with the increase of Cd concentration was also detected. The growth of radish, rocket and turnip plants exposed to salinity has been affected and main reductions in plant height and root length with salinity level were observed on the last growth stage (120 days). The results indicated that cadmium treatments had a greatest impact than salinity treatment. Moreover, percentage levels of nitrogen, phosphorus and potassium in leaves of treated different plant species have been affected by cadmium and salinity treatments. In conclusion, radish, rocket and turnip exposed cultivars showed variation in response to these stresses and confirms that species and genotypes crops are differ in their sensitivities to abiotic stresses.https://ejoh.journals.ekb.eg/article_172542_d93244bde26034ba4735305f05dd077c.pdfNational Information and Documentation Center (NIDOC), Academy of Scientific Research and Technology (ASRT)Egyptian Journal of Horticulture1110-020648220210801Enhancement of Vegetative Growth Criteria and Accumulation of Secondary Metabolites by Using Compost Tea and Paclobutrazol on Henna (Lawsonia inermis L.)

The experiment was arranged in a spilt plot design, the main plots were represented by four levels of foliar application of Amphora coffeaeformis algae extract (AC1= 0, AC2= 250, AC3= 500 and AC4= 1000 ppm) and the sub plot were split by Natural Elements Mixture included three levels (NEM1= 0, NEM2 = 2.0 and NEM3 =4.0 kg/tree /year). Data revealed that, NEM2 (2.0 kg/tree/year) gave more or less similar values as those of level NEM3 (4.0 kg/tree/year) especially for yield, TSS, TSS/acid ratio, total sugars, N, K, Fe, zn and Mn leaf content. Meanwhile, yield, fruit chemical properties, macro & micronutrients and proline content were significantly increased gradually by increasing algae extract level up to 500 ppm. In the most cases the difference between AC (500 and 1000 ppm) was insignificant. Concerning the interaction, treatments (NEM2x AC3), (NEM2x AC4), (NEM3x AC3) and (NEM3x AC4) gave more stimulating effects on most characters. So, treatments (NEM2x AC3) or (NEM2x AC4) were sufficient for helping to alleviate salinity stress and gave the highest values of yield, fruit quality and nutritional status.https://ejoh.journals.ekb.eg/article_178768_ec9a6397488b2a718396824cd5d8610e.pdfNational Information and Documentation Center (NIDOC), Academy of Scientific Research and Technology (ASRT)Egyptian Journal of Horticulture1110-020648220210801A Comparison of Some Traditional and Nontraditional Organic Fertilizers for Murcott Tangerine Trees Production and Fruit Quality24125518237110.21608/ejoh.2021.80073.1176ENNoha IbrahimMansourDepartment of horticulture faculty of Agricultur Ain Shams University0000-0002-3727-9303Mohamed Abd ElhamedNasserDepartment of Horticulture, Faculty of Agriculture, Ain Shams University, Cairo, Egypt.0000-0002-0328-2969Journal Article20210610This study was conducted during 2017/2018 and 2018/2019 seasons to assess the efficacy of some types and levels of nitrogen on vegetative growth, mineral content, yield and fruit quality of 5 years old Murcott tangerine trees (Citrus reticulate, Blanco.) budded on Volkamer lemon rootstock and cultivated in “Hegazi orchard” located in Cairo to Alexandria desert road, Egypt at 2.5 × 5m apart.

In the study, an incubation room (with an average of 20.33°C and 88.2% relative humidity) belonging to Yalova Atatürk Horticultural Central Research Institute and a warehouse with uncontrolled conditions were used. In this study, it was aimed to reproduce Fritillaria imperialis L. by different methods in different regions outside its natural distribution area and to monitor the development course of bulb groups under export size (10/12, 12/14, and 14/16 cm) in these locations. The best result in the reproduction of Fritillaria imperialis L. was obtained from the practice of incubating, cross-cutting application in the Küçükdeliller ecology, and the chipping application after the incubation process in the same ecology. Although there were losses in the number of bulb planted in both regions in the bulb groups under export size, increases in weight and circumference of the bulbs have been found over the years, especially in Küçükdeliller ecology. As a result of the research, it was determined that the ecology of Küçükdeliller is significantly better than the ecology of Yalova regarding the growth of bulb under export size.https://ejoh.journals.ekb.eg/article_189958_d7e3cf26a04da18cadf15a290c2119ca.pdfNational Information and Documentation Center (NIDOC), Academy of Scientific Research and Technology (ASRT)Egyptian Journal of Horticulture1110-020648220210801Antioxidant Procedure Improve Olive Cuttings Rooting During The Cool Season26727519106710.21608/ejoh.2021.74149.1172ENAhmedRashedyPomology Department, Faculty of Agriculture, Cairo University, Egypt.

This is due to the limited cultivated area, intensive cultivation, and increasing stress leading to problems that negatively affect production. While the investigations for determining the accurate fertilization amount of the grafted plants are still scarce. Therefore, this experiment was conducted in a private farm located in Badr city, El-Behera governorate, Egypt, to evaluate the performance of non-grafted (control) and grafted cantaloupe plants (Cucumis melo var. cantaloupenses, cv. Marella F1 hybrid) onto four rootstock cultivars (Cobalt, Ferro, Star, and 6001) then fertilized with nitrogen (N), phosphorus (P), and potassium (K) at rates of 60, 80, 100, 120, and 140% of these nutrients recommendations for cantaloupe fertilization during the two successive growing seasons of 2018 and 2019. The results indicated that grafting cantaloupe plants onto the tested rootstocks had promoted a higher vegetative growth manifested as plant length, leaves number, shoot fresh and dry weight, stem diameter, and root dry weight, as well as raising leaves content of nitrogen, phosphorus, potassium, and the greenness index (chlorophyll readings, SPAD) along with boosting the average fruit weight, and early and total yield than the control when all were fertilized by any of the applied fertilization rates.
