A field experiment was conducted in the open field during the
autumn season in year 2015 to study the effect of spraying with two
organic fertilizers (Crop + Extra, Cremalga) on flowering and yield
parameters of cultivars cucumber Maximus F1.
The investigation was conducted during 2013-2014 in Al-Moroj - Baniyas - Tartous.
The effect of grafting cucumber (Hybrid Amir F1 and Potenza F1) on (TZ 148 F1)
rootstock on growth and production was studied. The experiment contained 4 treatments
(ungrafted Amir F1 and Potenza F1, and grafted ones on Cucurbita hybrid).
The results showed that grafted cucumber (Amir F1) on (TZ 148 F1) was significantly
superior to other treatments in leaf area (15368.79 cm2.plant-1) and total production (21.58
kg .m-2). Grafting cucumber (Potenza F1) on (TZ148 F1) leaded to a significant decrease in
each of plant height (113.25 cm), number of secondary branches (7.5 branch . plant-1),
number of female flowers (94.13 flower . plant-1), number of fruits (38.13 fruit . plant-1)
and total production (14.61 kg .m-2). The earliness in grafted cucumber (Amir F1 and
Potenza F1) on (TZ 148 F1) (0.19 and 0.28 kg .m-2 respectively) was significantly
decreased compared to ungrafted plants (0.43 and 0.54 kg .m-2 respectively). Grafting on
(TZ 148 F1) didn't affected the fruit qualitative characteristics.
The research was conducted in plastic green house for the 2013-2014, in Alqangerh
village, about 5 Km from the city of latakia, in order to study the effect of spraying the
leaves with some humic compounds and amino acids on growth and production o
f hybrids
of cucumber (Novo,Dorruk).
Spraying leaves with three organic fertilizers are (Huzone, Mol mixs), and two boats
Dbalin and Amino vega (an amino acid).
The results showed that all treatments of leaves spraying with organic fertilizer geve
better resultus with significant differences than the control treatment in all the studied traits
of both hybrids: (stem length, number of branches/plant, number of leaves/plant, leave area
cm2, the number of flowers on the stem, number of fruits on the stem, number of floral
branches, number of fruits on the branches).The treatment of spraying achieved with
mixture of humic compounds and amino acids increase with significant differences in both
the number of leaves/plant, number of branches/plant, the plant's stem length and number
of fruit on the stem in the hybrid Novo. while the treatment of spraying achieved of hiozon
increase with significant differences the number of branches/plant, the number flowers on
the branches and number of fruits on the branches was in the hybrid Dorok. As for the
early production and total production, the treatment of spraying with mixture of humic
compounds and amino acids with significant differences on other transaction when both
hybrids Novo and Dorruk amounted, respectivety (5 ، 4,1 kg/m2 ; 16 ، 14,8 kg/m2 ).
We studied in this research the systemic activity of fungicide carbendazim in
cucumber plants (Hybrid F1 Milton). The soil was treated with fungicide with
concentrations of 0.25 - 0.5 - 1.0 - 2.5 g active ingredient per kg of soil and the month-old
plants was sprayed (three true leaves) with the recommended concentration 0.25 active
ingredient per liter of water, half and double of concentration. Bioassay method was used
to detection the systemic activity of fungicide by putting the plant parts in direct contact
with sensitive fungus spores within petri dishes that containing PDA.
It has been detected the presence of carbendazim in the root , cotyledonary leaves
and first real leaf after 20 days from treatment the soil for all concentrations, as it was
observed the fungicide persistence in plants after forty days. In the spraying treatment, It
has been detected the presence of carbendazim after one day for all concentrations and for
the recommended and double concentration only after five, ten and twenty days of
spraying.
This study was conducted in the village of Almetrkyah located in the southern
coastal plain of Lattakia city during 2014. In order to study the effect of Cucumber mosaic
virus on growth and development of two varieties of peppers, hybrid ESTAR F1 H
(sweet
pepper) and Demer(spicy pepper). This study included eight treatments, four treatments
for each variety. Plants were mechanically inoculated in three different stages, preflowering
bloom, flowering andpost-flowering stages each beside its non-inoculated
control. The result should that, the appearance of Cucumber mosaic virus symptoms on
infected sweet hybrid, was within four days before its appearance on inoculated spicy
variety,symptoms were leaf crinkle, leaf deformation, yellow patches and plant stunting.
Inoculated plants showed reduction in number of leaves, number of branches and yield.
Plants in pre flowering bloom stage were more effected by virus infection in both
varieties. Meannumber of leaves per plant of ESTAR F1 H hybrid were 130 in pre
flowering bloom stage compared with 170 leaf/plant in the control treatment. Mean
number of branches per plant of ESTAR F1 H hybrid were 43,4 branch/plant in pre
flowering bloom stage compared with 56,7branch/plant in the control treatment. Total
pepper production per plant was 700,8g in infected plants in preflowering bloom stage
compared with 1267,5g/plant in ESTAR F1 H hybrid control. Results of Demer variety
take the same results of ESTAR F1 H hybrid. The effect of virus infection on pepper plants
were reduced when inoculation were done during flowering stage and post-flowering stage,
differences were significant between inoculated plants in both varieties.
The research aims to Identify some species of aphids on plant families, and test the
possibility of transfer to the local isolate of Cucumber mosaic virus. Two species of aphids
in bean fields and citrus orchards have been defined, namely: Black be
an aphid Aphis
fabae and Cotton aphid Aphis gossypii, respectively, depending on the specialized
classification keys. The infection proved vital feedback and testing the function using
plants: Nicotiana tabacum and Chenopodium quinoa transfer each of the A. fabae and A.
gossypii local isolate of Cucumber mosaic virus.
The study was conducted on six varieties of cucumber: Napleon, Ampres,
Sendian, Prence, Samara and Baladi. To study the responses of these varieties
to drought stress, on the seed germination and seedling growth under different
Polyethylen glycol
concentrations (0 control, 10 mM, 20 mM and 40 mM PEG).
The results of this research showed a some varieties to its tolerance to drought
stress. The varieties Ampres, Prence and samara showed more resistance to
drought stress. It s indicated with increasing seed germination and growth of
seedlings with the higher concentration of PEG in compared to another
varieties.
The cucumber plants grown in field were sprayed with methomyl at dose
(60-g a.i./100 liter water).The objectives of this work were to study role of
somehome Preparation (washing and peeling) in elimination of methomyl
residues from contaminated cu
cumber fruits. The washing processes caused
removal of residues methomyl from contaminated cucumber fruits that
collected at intervals: 1,3 days after one application by percent loss reached:
72,60 %, respectively.
The percent loss reached: 37.7, 45.8 % in cucumber fruits that collected at
intervals: 0, 2 days, respectively after two applications. The peeling processes
caused removal of residues methomyl from cucumber fruits that collected at
intervals: 0, 3 days after one application by percent loss reached: 58.75, 57.14
%, respectively. and in cucumber fruits that collected at intervals : 0, 2 and 3
days after two applications ,the percent loss was: 55, 62.7 and 34.6 %,
respectively.
Three identical gable-even-span greenhouses were designed, constructed
and installed at the Agricultural and Veterinary Research Station of King
Faisal University in order to produce cucumbers during the winter season.
These experimental greenhous
es were covered by ٠,٨mm thick fiberglass
reinforced plastic. Two different solar heating systems were designed, built and
employed to heat the ambient air temperature inside the greenhouses. The
design of the first one was a surface heating system suspended and fixed on the
southern side of the gable roof of one greenhouse. The second solar heating
system was a solar panel, which was designed, built and situated outside of the
other greenhouse.
