The purpose of the research was to study the effect of priming duration (6, 8 and 10 hours) and seed priming (hydro-priming, 50, 75 and 100 mgL<sup>-1</sup> of salicylic acid, 1, 2 and 3 % of KH<sub>2</sub>PO<sub>4 </sub>and 1, 2 and 3 % of ZnSO<sub>4</sub> ) and dry seed on improving germination of seed and seedling vigor of white hybrid teosinte<strong>. </strong>Results indicated that six hours priming duration gave the highest germination percentage, seedling vigor, speed germination index and seedling vigor index. Seed treatment with 2 % of KH<sub>2</sub>PO<sub>4 </sub>was the best treatment followed by salicylic acid 100 mgL<sup>-1</sup> and 3 % of ZnSO<sub>4</sub> recorded the highest seed germination%, seedling vigor, speed germination index and seedling vigor index. Hydro-priming produced the higher values of most traits such as plumule and radical length, seedling dry weight, speed germination index and the lowest in electrical conductivity. The interaction effect was significantly where six hours duration and seed priming with 2% KH<sub>2</sub>PO<sub>4,</sub> 3% of ZnSO<sub>4 </sub> and 100 mgL<sup>-1</sup> of salicylic acid were the highest germination% and seedling vigor and insignificant with hydro-priming.

Six parameters model was used in three wheat hybrids under optimum sown (25<sup>th</sup> Nov.) and late sown (25<sup>th</sup> Des.). The results cleared that the (P<sub>1</sub>, P<sub>2</sub>, F<sub>1</sub>, F<sub>2</sub>, Bc<sub>1</sub> and Bc<sub>2</sub>) mean values in late sown were less than the optimum sown for all the studied characters in all hybrids. Heterosis relative to mid-parent and better parent was found to be positive significant for most characters under optimum and late sowing dates. The relative consequence of additive and dominance effects differed for characters in all hybrids under two different sowing dates. Dominance effects were generally more important than additive for most the characters in all the studied hybrids under two different sowing dates. Indicating, dominant genes played a part in the inheritance of these characters. Dominance × dominance gene interaction was higher in extent than additive × additive and additive × dominance in most the studied traits under two different sowing dates. Indicating, these traits are greatly influenced by dominance and dominance x dominance interactions. Therefore, it is approved to lateness selection to late segregating generations to raise homozygosity. Heritability values in narrow sense were moderate to high for all the studied characters in all hybrids under two different sowing dates. Genetic advance was ranged from low to high for all characters in all hybrids under two different sowing dates.https://jpp.journals.ekb.eg/article_220181_d76b787a0969f8e07b6239247fb61e94.pdfMansoura University, Faculty of AgricultureJournal of Plant Production2090-3669121220211201Production of Tomato Lines Tolerating to Salinity Using In-Vitro Culture Technique1351135722018410.21608/jpp.2021.220184ENTahany R.El-sayedDepartment of Vegetable Breeding, Medicinal and Aromatic Plants, Horticultural Research Institute, Agricultural Research Center (ARC), Giza, EgyptJournal Article20220217Salinity is one of the major stress between the abiotic stresses for plants worldwide. This study aimed to investigate and evaluate variations in salt tolerance of four tomatoesgenotypes (Super strain B, Castle Rock, Edkawy and Advantage II) under laboratory conditions using different concentration of NaCl. The cotyledon explants were cultured in MS media containing 0.5 mg/l BA and 0.5 mg/l Kin under different concentration of NaCl (0.0, 3.0, 6.0, 8.0 and 11.0 gm/L). Cotyledon culturability traits such as the percentage of each callus induction, plant regeneration, rooting, number of shoots, shoot length, roots number, root length and the plantlets number were measured to evaluate the salinity tolerance. All growth traits decreased with increasing of NaCl concentration in the culture media. The results suggested that the Edkawy genotype was the best for the percentage of plant regeneration (79.33%), percentage of rooting (54.66%), length of the shoot (7.46 cm), length of the root (5.73 cm) and callus fresh weight (2.72 gm) compared with the other genotypes under different levels of NaCl. Super Strain B and Castel Rock genotypes gave the highest shoots number and plantlets number (13.00 ,13.06 and 4.66 ,4.00 respectively). Advantage II genotype gave the lowest values for almost traits except the percentage of callus induction which was the best value (90%). Super Strain B genotype appeared the best in the percentage for callus induction (53.33%), percentage of plant regeneration (36.66%) and length of the shoot (4.66 cm) under the highest salt concentration (11.0 gm/L).https://jpp.journals.ekb.eg/article_220184_5afc89f255e63f0b37f4657e4996cf92.pdfMansoura University, Faculty of AgricultureJournal of Plant Production2090-3669121220211201The Efficiency of Clonal Selection as A Breeding Program to Improve Chinese Garlic Cultivar (Allium sativum L.)1359136522338210.21608/jpp.2021.223382ENE.

Nine clones were reached by the end of the selectorial program, which were evaluated during the seventh season along with the original population. In general, the selected clones of the Chinese garlic cultivar showed significant superiority compared to the original population for all the selected traits. Among the most prominent clones that showed superiority for the characteristics of bulb weight, cloves weight per bulb, as well as the productivity; three clones C5, C4, and C3 compared to the rest of the selected clones as well the original population. While the two clones C1 and C8 showed the highest average clove weight and the lowest cloves number per bulb compared to all the tested entries. On the contrary, the original population gave the lowest bulb weight, the lowest cloves weight per bulb, the highest orbits number per bulb, and the highest cloves number per bulb with minimum clove weight also produced the lowest total yield per feddan.https://jpp.journals.ekb.eg/article_223382_e97a30980a7446eeaa14a68dfd954757.pdfMansoura University, Faculty of AgricultureJournal of Plant Production2090-3669121220211201Mitigation of Salinity Stress in Fenugreek Plants Using Zinc Oxide Nanoparticles and Zinc Sulfate1367137422019410.21608/jpp.2022.112376.1078ENHend M.SwaefyOrnamental Horticulture Department, Faculty of Agriculture, Cairo University, Giza, EgyptAmany M.AbdallhAgronomy Department, Faculty of Agriculture, Cairo University, Giza, EgyptZeinab K.TahaAgricultural Botany Department, Faculty of Agriculture, Cairo University, Giza, EgyptJournal Article20220217Salinization is increasing on a global scale, and improving the tolerance of plants to salinity is urgent to study, so this study was conducted at the Department of Ornamental Horticulture, Faculty of Agriculture, Cairo University, Giza, Egypt during two successive seasons 2019 and 2020 to evaluate the effect of zinc sulfate and ZnO nanoparticles treatments as a foliar application at the level of 0, 20, and 40 ppm on some morphological and chemical features of <em>Trigonella foenum-graecum</em> plants grown under three salinity levels (0,1500, and 3000 ppm) aiming to reduce the negative effect of salinity on plant growth. The present study revealed that salinity stress caused a decrease in morphological traits (shoot length, number of branches/ plant, number of leaves/ plant, shoot fresh weight, shoot dry weight, root length, root fresh weight, and root dry weight) and harvest traits (number of pods/plant, number of seeds /pod, and 100 seed weight), as well as total phenols, and K<sup>+</sup> /Na<sup>+</sup> ratio. While, using zinc sulfate and ZnO nanoparticles gave high results with all studied morphological traits, and also improved the harvest characteristics of the fenugreek plants. The highest 100-seed weight and total saponins were obtained by the interaction between the treatments of ZnO nanoparticles at 40 ppm and salinity at 1500 ppm.

The present study investigated the effect of naphthalene acetic acid (NAA) as plant growth regulator, applied as soaking on the yield, its components of yielded grains and quality of bread wheat cultivars under calcareous conditions. Moreover, the study aims to determine suitable concentration of NAA as exogenous treatment to enhance wheat cultivars tolerance to calcareous soils. Grain soaking with five levels of NAA, at (0, 5, 10, 15 and 20 ppm) on three wheat cultivars (Misr -1, Gemmiza- 11 and Giza- 169) and irrigated from artesian well water (1780 ppm). Obtained results showed that increasing of NAA from 5 up to 15 ppm, significantly increased all yield, yield components and protein contents in each growing seasons. Misr- 1 cultivar was superior to Gemmiza-11 and Giza-169, in both seasons. NAA at 20 ppm was recorded as superior than 15 ppm for all yield criteria with Misr-1, in the two seasons. It was observed that 20 ppm concentration of NAA showed better results in enhancing the straw and grain yields of the wheat cultivar, Misr-1 coinciding with producing high yield, yield attributes and protein content under Mariout Region, Egypt. Therefore, the application of NAA, at 20 ppm and Misr-1 on wheat under calcareous soils was more effective of yield, yield components and quality.https://jpp.journals.ekb.eg/article_220205_61a07e6d102e51204c3db2dc2ea8153d.pdfMansoura University, Faculty of AgricultureJournal of Plant Production2090-3669121220211201Effect of Magnetic Water Irrigation and Biochar on Fruiting and Fruit Characteristics of Hayany Date Palm Cultivar under North Sinai Conditions1389139822310510.21608/jpp.2021.223105ENS.
