To achieve this goal, five different net potassium levels: 0, 60, 90, 120, and 150 kg/Feddan were applied and potato tubers were harvested at two harvesting times: 90 and 105 days after planation. The results reported that both potassium application and harvesting time as well as their interaction significantly affected most of the studied traits. The highest values of plant height, plant fresh weight, plant dry matter, tuber dry matter, marketable yield/feddan, total yield/feddan, soluble solid content (SSC), nitrogen (N) content  and potassium (K) content  were obtained from the plants received 120 kg K and harvested at 105 days after planation. While, the potassium fertilized plant at 120 kg/feddan and harvested at 90 days achieved the maximum values of total yield per plant, total sugar and non-reducing sugars. However, the difference between these two treatments was not necessarily significant for some traits. In addition, the results of the current study interestingly clarified that potassium level (150 kg) negatively affected some yield attributes in both harvesting times compared to the other potassium levels. Consequently, the result of the current study indicates that high level of potassium (120 kg) can hasten the earliness of potato, which may achieve notable financial profits for potato growers.","PeriodicalId":395567,"journal":{"name":"Hortscience Journal of Suez Canal University","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121989388","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All studied mango genotypes (G) differed in dates of full bloom, maturity stage, bearing habit, floral malformation and fruit characteristics. All genotypes had commercially acceptable qualities and produced relatively high yield ranged from 298.7 - 394 Kg/tree. Generally, genotype No. 9 recorded the highest value (96.6%) in the general evaluation according to yield, Biennial bearing and fruit quality, followed by genotypes No. 7 and No. 5 which scored 94.0 and 91.8%, respectively. In general, these three genotypes possessed most of the desired commercial attributes of international standard. In addition, further understanding of the structure of genetic diversity was done using nine SSR markers based on their scorability, repeatability and capability to differentiate among studied genotypes. Also, analyze of DNA fingerprinting data to create molecular IDs was done to get an idea for the conservation and protection of studied genotypes. The nine SSR loci produced a total of 32 alleles with 97% polymorphism and observed alleles per locus diversified from 1 to 8 alleles with an average of 3.6 without zero alleles. The observed heterozygosity (Ho) within the loci ranged from 0.0 to 0.55 with an average value of 0.23, heterozygosity level within the genotypes varied from 0.11 to 0.44. The polymorphic information content (PIC) values ranged from 0.0 to 0.86 with an average value of 0.49, whereas the mean of discriminating power (DP) for all loci was 0.51. Regarding the probability of matching fingerprints, none of the genotypes were different or similar at all loci with any of the rest genotypes and this value ranged from low to medium with an average of 0.48. The similarity degree ranged from 0.18 to 0.90 with an average of 0.53, indicating that the genetic differences were moderate among mango genotypes under study. Whereas, seven of these genotypes produced 11 unique bands maybe accompanying to  number of novel functional alleles, which can be used in mango improvement.","PeriodicalId":395567,"journal":{"name":"Hortscience Journal of Suez Canal University","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127922135","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results showed that the concentration of total alkaloids was increased by 2.7 and 2.3 times after exposure to UV-C for 2 or 3 h, respectively more than unstressed callus. Also, data of HPTLC revealed that 2 h exposed-callus accumulated the highest amount of hyoscyamine which similar to the amount in wild leaves but it was more 3.1 times than control. Increment of alkaloids concentration was attributed with high accumulation of non-enzymatic antioxidants as free amino acids, free phenolics and glutathione and increased of peroxidase and superoxide dismutase activity as well as reduction of H2O2 concentration. Also, 2 h exposed-callus to UV-C showed high expression of electrophoretic protein bands with molecular weights 109, 42 and 29 KDa. All exposure times to UV-C increased both fresh and dry weight of callus compared to unstressed one. Short exposure time of UV-C enhanced the amount of Chl. a and b in callus than other treatments. All exposure periods of UV-C decreased the concentration of carotenoids, anthocyanine, proline and total carbohydrates than control. Long exposure period of UV-C modified the callus cells shape by induction large spherical cells and lysigenous intercellular spaces. It can be concluded that 2 h exposure time of UV-C is effective treatment for enhancement both alkaloids and hyoscyamine content in callus of Egyptian henbane.","PeriodicalId":395567,"journal":{"name":"Hortscience Journal of Suez Canal University","volume":"130 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127044273","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In vitro culture response was assessed in tomato (Solanum lycopersicum L. var. cerasiforme) cv. (Summer Cherry) for optimum callus induction and plantlet regeneration. Callus induction was achieved within eight to 12 days directly on the cut surfaces of hypocotyl, cotyledon and leaf disc explants cultured on Murashige and Skoog (MS) basal medium supplemented with various concentrations of Thidiazuron (TDZ)] and benzyl adenine (BA) alone, but not in hormone free-medium. The highest callusing index (3.9 and 3.7) was obtained on hypocotyl explants cultured on MS medium supplemented with TDZ(1.0 and 2.0 mgl) followed by an index of 3.5 obtained from the same explant by using 0.5mgl BA. However, for the leaf disc explants, the highest callusing index (3.1) was obtained on MS medium supplemented with BAat 2.0 mgl. After 8 weeks of culture, organogenesis was observed only on the explants cultured on medium containing different concentrations of TDZ and BA. The best shoot formation (93%) was obtained from leaf disc explant callus induced on MS medium containing TDZ. The highest number (13.4) of shootsexplant was found when cotyledon explant callus was sub cultured on MS medium supplemented with 2.0 mgl TDZ. Half strength of MS was found to be the best rooting medium, however, addition of IAA at 1.0 mgl and IBA at 2.0 mgl were found necessity to induce highest number of roots (22.5) and longer roots (11.0 cm), respectively. Acclimation of in vitro rooted plant is important for testing the post culture behavior of tissue culture regenerated plants. Cherry tomato derived from different explant sources under different concentration of TDZ and BA were not significantly different in their vegetative characters to those obtained from seed. However number of (raceme plant, flower raceme, fruit raceme, fruit plant ) which produced by seed-derived plants was significantly less than those derived from in vitro propagated plants. This protocol would be valuable to create somaclonal variation and develop transgenic approaches for varietal improvement of cherry tomato.","PeriodicalId":395567,"journal":{"name":"Hortscience Journal of Suez Canal University","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114074758","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To achieve this goal, two field experiments were performed during winter seasons of 2015/2016 and 2016/2017. Four concentrations of GABA (0, 1, 2 and 4 mM) were sprayed on two garlic's genotypes (Sids 40 and Egaseed). The results reported that exogenous supplementation of GABA notably improved vegetative growth (plant height and plant fresh weight), yield traits (bulb weight and total yield), and minerals content (N, P, K and Ca), as well as the content of organic compounds (total chlorophyll and total phenols) compared to non-treated plants (control) in both genotypes. It was clearly revealed that 1 mM GABA treatment had achieved the highest morphological traits, yield traits, chemical composition and organic compound content compared to the other GABA treatments. The findings indicate that GABA application has the ability to enhance growth and productivity of garlic through enhancing mineral composition and organic compounds.","PeriodicalId":395567,"journal":{"name":"Hortscience Journal of Suez Canal University","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127947430","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Grafted and un-grafted seedlings were grown in the field under low temperature during Jan.-Apr. to be compared to those growing under normal warm season conditions (Mar.-Jun.). Results indicated significant decrease in growth, yield, chlorophyll, and carotenoids in all grafted plants, in different degrees, depending on the graft combination. In this regards, plants of Aswan/Ferro recorded more than double the marketable yield of ungrafted ones under sub-optimal temperature, indicating the relative tolerance of Aswan/Ferro to cold stress. While, ungrafted plants exhibited the highest decline in all growth and yield parameters. Leaf proline content and the activities of anti-oxidant enzymes (SOD and CAT) were higher under cold stress than the control. It is concluded that grafted watermelon plants were relatively tolerant to sub-optimal temperature than un-grafted ones which could enable the production of out of season crop.","PeriodicalId":395567,"journal":{"name":"Hortscience Journal of Suez Canal University","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116235722","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
