Abstract

The study was devoted to evaluate the effect of storage periods, storage methods of wheat grains and fumigation with (phosphine, neem oil, citronella oil, and malathion) on storage efficacy, seed germination, seedlings parameters and quality of wheat seeds. The following major results were achieved:
1- Storage periods of wheat seeds exerted a significant effect on power of germination percentages which showed regular decrease from 95.68%, 91.97%, 81.81% as a result of increasing storage periods from 0 to 6 and 9 months respectively.
2- Storage periods of wheat seeds exerted a significant effect on germination percentages which showed regular decrease from 95.39%, 85.55%, 82.27% as a result of increasing storage periods from 0 to 6 and 9 months respectively.
3- Fumigation of wheat seeds with phosphine at the rate of 0.018 g/2kg exerted a significant effect on viability and quality traits (the best treatment).
4- Storage methods of wheat seeds significantly effect on viability and quality traits (the best package glass jars).
5- Power of germination was significantly affected by the interaction between storage periods, storage of methods, and fumigation. The highest percentage of power of germination (96.67%) was observed at the beginning of storage period for 6 months in sealed stored (glass jars) wheat seeds fumigated with ,018 g/2kg of phosphine.
6- Germination percentage was significantly affected by the interaction between storage periods, storage methods, and fumigation. The highest value (94%) was detected at the beginning of storage period for 6 months in sealed stored (glass jars) wheat seeds fumigated with 0.018 g/2kg of phosphine. The minimum power of germination percentage (82.67%) was obtained from samples of wheat grains stored in twisting plastic packages and fumigation with malathion at the rate of 2 g/2kg for 9 months.
7- The interaction among storage periods, storage methods, and grains treatment had a significant effect on abnormal seedlings. The highest value (7.333) was detected when wheat seeds were stored for 9 months, fumigated with malathion and stored in polyethylene package.On the other hand, the lowest value (3) occurred insealed stored (glass jars) wheat seeds fumigated with0.018 g/2kg of phosphine in wheat seeds stored for 6 months.
8- The interaction among storage periods, storage methods, and grains treatment had non-significant on root and shoot lengths of wheat seedlings.
9- Seedling dry weight of wheat not significantly responded to the interaction among storage periods, and grains treatment.
10- Test weight (kg/ha) of wheat seeds significantly responded to the interactions among storage periods, storage methods, and grains treatments. Maximum value of test weight (67.33 kg/ha) was recorded from wheat samples stored in polyeth0 months.
11- Seed index (1000 K. W.) of wheat was significantly affected by storage periods, storage methods, and grains treatments. Maximum value of seed index (58) was recorded from wheat samples stored in polyethylene bags and treated with neem oil at the rate of 10 ml/2kg for 0 months.
12- Gluten content of wheat flour was not significantly affected by interaction among storage periods, storage methods, and grains treatments.
13- Fermentation time test of wheat dough was not significantly affected by interaction among storage periods, storage methods, and grains treatments.
14- Flour percentage of wheat was significantly affected by interaction among storage periods, storage methods, and grains treatments. Maximum value of flour percentage (81) was recorded from wheat samples stored in gunny bags and treated with phosphine at the rate of 0.018 g/2kg for 0 months.
15- Coarse bran percentage was significantly affected by interaction among storage periods, storage methods, and grains treatments. Maximum value of coarse bran (21) was recorded from wheat samples stored in polyethylene bags and treated with citronella oil at the rate of 4.5 ml/2kg for 9months.
16- Maximum value of fine bran percentage (2.667) was produced from fumigated with phosphine stored for 0 months
