The oil samples were analyzed immediately after pressing and then stored for3, 6 and 9 months. Significant differences were found for the type of packaging and storage duration on the degree of oil's acidity and the peroxide number and its content of some fatty acids, so that these properties were the least affected by glass containers, while plastic and metal containers were most affected, especially in oil stored for nine months. Acidity increased from 0.32% in fresh oil directly after pressing to 0.38 in glass containers and 0.44 in plastic packaging after 9 months. Peroxide number increased from 3.50 mmol / O2 / kg oil to 0.38 in glassstored oil and to 6.20 mmol / O2/ kg oil in oil stored in plastic containers for nine months. The percentage of oleic acid decreased from 70.75% in olive oil samples taken immediately after pressing to 68.48% in olive oil stored in plastic containers and 68.65% in plastic bottles after nine months. The percentage of linoleic acid in the oil stored in the plastic containers decreased after nine months (0.79%) compared to its value in the samples taken from plastic packaging after six months (0.84%) Therefore, the glass containers were the best in preserving the properties of the olive oil studied.

Research paper thumbnail of EFFECT OF SALINE STRESS ON GROWTH OF FRUIT PLANTS (REVIEW ARTICLE

Mesopotamia J. of Agric, 2020

Soil and irrigation water salinity are among the main problems hindering agricultural development... more Soil and irrigation water salinity are among the main problems hindering agricultural development, especially in arid and semi-arid regions, which depends on especially surface irrigation as the main means in agriculture. The salinity lead to low growth and production of plants, including fruit, as a result of the temporal, azalotic, or nutrients imbalance. Salinity of the soil or irrigation water greatly reduces the growth, productivity and quality of fruit crops by affecting their physiological, chemical and biological functions as they cause obstruction to the absorption of some elements by the plant and if it increased absorption of salts, it causes ion poisoning of the cell, as well as increased salts cause less absorption of water by the plant due to the high osmosis of soil water. There are many ways to reduce the salt stress in the growth of fruit plants, the most important of which is adding organic fertilizers such as humic acid or spraying with the amino acid proline.

The salinity lead to low growth and production of plants, including fruit, as a result of the temporal, azalotic, or nutrients imbalance. Salinity of the soil or irrigation water greatly reduces the growth, productivity and quality of fruit crops by affecting their physiological, chemical and biological functions as they cause obstruction to the absorption of some elements by the plant and if it increased absorption of salts, it causes ion poisoning of the cell, as well as increased salts cause less absorption of water by the plant due to the high osmosis of soil water. There are many ways to reduce the salt stress in the growth of fruit plants, the most important of which is adding organic fertilizers such as humic acid or spraying with the amino acid proline.

Dept. /College of Agriculture and Forestry during 2018 season to study the effect of two spring budding dates (2 and 17 April) of local orange Citrus sinensis on sour orange seedlings Citrus aurantium, and adding of chemical fertilizer (NPK), organic fertilizer (Nutrigreen) and the biological fetilizers (Biogeain, Potsiomag and Fulzyme) on the following growth of the budded seedlings. The studied factors were as follows:
1- Spring budding dates (2 and 17 April)
2- chemical fertilizer (0 and 30 gm.seedling-1).
3- Seven levels of biological and organic fertilizers:
a- Zero.
b- Biogeain (3 and 6 gm.pot-1).
c- Potsiomag (5 and 10 gm.pot-1).
d- Fulzyme (1 gm.pot-1).
e- Nutrigreen organic fertilizer (6 ml.seedling-1).
The study was performed by using split split plots within factorial experiment in randomized complete block design (RCBD), with 3 factors and 3 replicates, by using 5 seedlings for each treatment, so the number of seedlings will be 2×2×7×3×5=420 seedlings. Treatment means were compared by using Duncan multiple levels at 5% p. the more important results obtained were as follows:
1- 2nd April budding date was superior significantly on 17th April date budding in budding success percent (44.76% and 31.42%, respectively). Also 2nd April budding date was effective significantly in vegetative growth characteristics (budding length, leaves number, leaves area, leaves wet weight, leaves chlorophyll content, leaves protein, carbohydrates and nitrogen percent. In contrast no superiority were noticed of the second budding date except in leaves dry weight, where, no significant differences were noticed in the other characteristics.

2- NPK addition had no effects on all of studied traits, as control treatment was superior in budding success percent, budding length, leaves number, leaves area, growth number, leaves chlorophyll content, leaves protein and carbohydrates content, leaves nitrogen and phosphorus percent and the available nitrogen and phosphorus in the soil, as compared with 30 gm.seedlings-1 of NPK.

3- Addition of Potsiomag biofertilizer resulted in an increment in budding success percent and most of vegetative growth (budding length and diameter, leaves number, leaves area, leaves dry weight, leaves chlorophyll, protein and carbohydrates content), and root growth (dry weight and dry matter weight percent), leaves nitrogen and phosphorus percent and potassium content of the soil. Also biogeain biofertilizer addition resulted in an increase in leaf area, leaves wet weight and available nitrogen of the leaves as compared with control treatment. While, fulzyme biofertilizer treatment recorded a significant increase in phosphorus content of the leaves and soil as compared with control treatment, which resulted in a significant increase in leaves sodium and soil pH.

4- Interaction between the factors resulted in a significant superiority in the studied characteristics, as the interaction between 0 NPK + 5 and 10 gm.pot-1 of Potsiomag bio fertilizer for the first budding date seedling have the highest values of budding success percent, budding length and diameter, leaves number, leaves area, leaves wet and dry weight, leaves chlorophyll, protein and carbohydrates content, dry weight of the roots, leaves nitrogen and potassium content and available phosphorus and potassium content of the soil.
