Creasing incidence, its possible relationship with the role of protein and enzyme activities were approached. A research study was conducted for two consecutive seasons to monitor and evaluate the protein and enzyme activities in creased and non-creased fruits of Washington navel orange in Delta, Egypt. Further parameters such as fruit physical and chemical characteristics were measured as well as the percentage of creased fruits as affected in three dates i.e. mid Jan., first of Feb. and first of March and two tree geographical directions, i.e. north and south. The obtained data revealed that creasing percentage was increased progressively with fruit aging, and creasing incidence was relatively influenced by geographical direction (more pronounced in fruits of northern tree periphery). Meanwhile, the protein banding patterns of albedo and flavedo total proteins exhibit the association between some particular protein types and the changing in citrus peel tissue from healthy to crease. Moreover, the higher amount of PG-ase release was tended to be closely related to albedo taken of creased fruits compared to non creased ones.}, keywords = {Washington Navel orange,creasing,PG-ase activity,Protein banding patterns}, url = {https://ejoh.journals.ekb.eg/article_1064.html}, eprint = {https://ejoh.journals.ekb.eg/article_1064_f244e3cea51df8b1b19731054c83132b.pdf} } @article { author = {}, title = {Evaluation of Three Peach Cultivars (Prunus persica L.)

Seventeen mono-embryonic Indian mango varieties grafted on local Omani rootstock were studied with respect to growth, yield and quality attributes. The results revealed that there was a variation between varieties with respect to their vegetative growth parameters which had large variation viz. 3.10- 7.5 cm for tree height, 3-7 m vegetative growth spreading, 45-98 cm for trunk girth and 15.09-195.06 m3 tree vegetative canopy volume.

On the other hand, weight of fresh root was significantly higher when saddle grafting was done in the first season, while in the second the superior values were recorded with grafting by tongue method on 15th January. As for the  union zone, it showed the highest values on 15th January, when the plants were grafted by saddle grafting in the first season and by cleft grafting in the second one.

Also, when the grafting was done on 15th Jan. in the first season and 15th Feb. in the second season, using saddle grafting method, the maximum length of sprouted shoots was produced.

Morphological characteristics of both apple rootstocks Balady and MM106, negatively responded to the raising of NaCl concentrations in vitro such as callus survival and regeneration percentages, plantlets length (cm), number of multiple shoots, number of leaves/plant, number of roots/plant and root length (cm).

The mean of regeneration percentage reached the maximum number with control (38.67 %), and decreased gradually with higher NaCl concentrations until it was (23.67%) with 3000 mg/l. It was feasible that salinity did not reduce the average length of shoots. Number of multiple shoots was affected by raising salinity level into medium. The highest significant value was obtained with control (0.00 NaCl) (14.00) while, the lowest significant Value was (8.50) with 3000 mg/l.

The present study investigates additional treatments that may improve productivity and fruit quality of Superior grapevine. In this respect, the vines were subjected to: root pruning (RP), foliar application with either ethephon (ET) or mepequat chloride (MC). The vines were root-pruned along both sides of vine to a depth of 50 cm and 30, 45 or 60 cm from the trunk. Whereas ET and MC were sprayed at the concentration of 100, 200 or 300 ppm and at 100, 150 or 200 ppm, respectively. All treatments were carried out at two weeks before bloom. The obtained results clearly showed that RP at 30 or 45 cm as well as all MC and ET treatments reduced shoot length, which in turn increased the intensity of light reaching the center of the vine. RP at 30 cm was significantly the highest in this respect followed by MC at 150 and 200 ppm. As a general trend all mepiquat treatments induced increment in the total carbohydrates stored in shoot tissues of treated vines compared with untreated ones. In addition, plant content of N, P and K showed different fluctuations. However, MC treatment seemed to enhance shoot content of N and K. In general, these effects were associated with an enhanced in vine productivity during following treatments season. RP mainly at 30 cm as well as MC application at 150 and 200 ppm resulted in significantly increased fruitfulness, whereas both ET applications (200 and 300 ppm) significantly decreased it. However, all MC treatments produced the heaviest bunch. Therefore MC gave the highest yield / vine while the lowest yield was recorded for ET followed by control treatment. In conclusion, treating Superior vines with MC at medium (150 ppm) or high (200 ppm) concentrations could be recommended to an increase light density inside vine canopy as well increasing fruitfulness, number of cluster / vine, average berry or brunch weight and in turn vine yield.}, keywords = {grapevine,Superior,Root Pruning,Mepiquat chloride,Ethephon,productivity,yield,fruit quality}, url = {https://ejoh.journals.ekb.eg/article_1306.html}, eprint = {https://ejoh.journals.ekb.eg/article_1306_24aaa6b950ec433f42845da8096a3324.pdf} } @article { author = {}, title = {Effects of Some Edible Coating on the Quality and Shelf-Life of Pioneer Plum Fruits (Prunus salicina L.) at Room Temperature}, journal = {Egyptian Journal of Horticulture}, volume = {42}, number = {Issue 1 The 2nd International Conference on Horticultural Crops, 15-18 March ( ICHC- Egypt 2015)}, pages = {419-426}, year = {2015}, publisher = {National Information and Documentation Center (NIDOC), Academy of Scientific Research and Technology (ASRT)}, issn = {1110-0206}, eissn = {2357-0903}, doi = {10.21608/ejoh.2015.1307}, abstract = { THE INVESTIGATION was carried out during 2013 and 2014 …… seasons from selected 4 years old plum cv.

The use of fungicides is restricted in most countries, and there are problems due to the negative effects they may have on the human and environmental health, and on the selection of fungicide-resistant strains of the pathogen. The use of naturally occurring antagonists to control storage decay and increase product quality represents a practicable alternative to chemical fungicides. However, the mechanisms of action for most of the antagonists investigated have not yet been fully elucidated, because of the difficulties due to the complex interactions between host, pathogen, antagonist, and others microorganisms occurring in the site of interaction. Among the desirable characteristics of microbial antagonists is included the ability for siderophores production. Several phyllosphere yeasts species are known to produce hydroxamate-type siderophores, iron-binding compounds in response to Fe-stress conditions. In this research, more than 100 red yeasts were isolated from the surface of organically and conventionally trained grape berries and leaves, orange fruits, and olive drupes. The ability to produce siderophores was scored qualitatively, and the most active isolates were selected for further biocontrol activity tests against Botrytis storage rot on apple fruits.

In this investigation, the complemented effect of putrescine amine (put), biofertilizers and mycorhiza on date palm zaghloul genotype irrigated with salinized water and grown in reclaimed salinized soil was studied. The data indicated that the selected plant growth promoting rhizobacteria in the presence of putrescine amine make and/or enable date palm zaghloul genotype to increase its tolerance and adaptation to grow in the reclaimed-salinized soil. The treatments reduced salt-induced oxidative damage, increased productivity of date palm and improved its fruit quality. These results may be due to the increase in the photosynthetic pigments, organic solutes, promoting growth substances (GA, IAA and cytokinins), and activities of oxidant enzymes. Moreover, a decrease in the levels of lipid peroxidation and inhibitor substances (ABA) may be related. The most effective interaction treatments were pronounced at 2.5 mM putresine due to more increase in the activities of ascorbate peroxidase (APOX) glutathione reductase (GR) and superoxide dismutase (SOD) and more decrease in lipid peroxidation. The interaction treatments with put at 5 mM increased disamine oxidase (DAO) and polyamine oxidase (PAO) activities compared to the other interaction treatments. The activates of these two enzymes produce hydrogen peroxide H2O2 which may act in structural defense as a signal molecule and decreasing the production of polyamines against salt-induced oxidative damage in date palm.
