A Study was carried out to evaluate the ability of the methanolic, hydro and oily
extractions of anise seeds (Pimpinella anisum L.) to inhibit the growth of the pathogenic
fungi Fusarium oxysporum and Aspergillus niger. The results showed a good in
hibition
ability of the alcoholic and hydro extractions on the growth of the studied fungi. The
inhibition ability differed due to the used concentrations. When the methanolic extraction
was used by concentrations (2, 4, and 6) mlg/ ml at the seventh day, the inhibition ability
was (42.5, 50.6 and 64.4)% of the fungus F. oxysporum, respectively. And was (23.6, 42.7
and 55.1)% of the fungus A. niger, respectively. Whereas when the hydro extraction was
used by the same concentrations, the inhibition ability was (59.2, 65.3 and 70)%
respectively for the fungus F. oxysporum, and (46.1, 58 and 61)% for the fungus A. niger,
respectively. The oily extraction showed high inhibition ability, where the inhibition rate
was 100% when the extraction was used by the two concentrations 50 and 75 μl for both
two studied fungi.
The study aimed to estimate water requirements for Anise, the crop
coefficient, and the effect of three water stress treatments out of full irrigation
amount respectively) on its yield
This research was carried out at the farm of Faculty of Agriculture,
Damascus University, during 2010-2011 growing season to determine the effect
of seedling rate on yield traits (plant number at harvesting, plant height,
number of umbels/plant, n
umber and weight of seeds/ umbel, plant dry weight,
seed yield and harvest index.) of four ecogenotypes of Anise plants, (Pimpinella
anisum L.) collected from different places of Syria: Damascus countryside
(Hena, Saasaa), Homs and Edlib. Sowing rates were 10, 15 and 20 Kg/ha.. Trial
was laid out using completely randomized block design with three replicates for
each treatment. Results showed that studied traits differed according to seeding
rate and the ecotype. There were significant differences for the treatment of
seeding rate of 15 kg/ha., on seed yield. Regardless the ecotype, increasing the
seeding rate up to 20 kg/ha. resulted in maintenance of highest number of
plants/unit area, but accompanied with reduction in fertile umbels and seed
weight. Statistical analysis showed that the ecotype of Edlib recorded the
highest seed weight/ plant and highest seed yield/ planted area, especially with
the seeding rate of 15 kg/ha. However, the results showed the seed components
of Anise (plant number at harvesting, weight of seeds/ plant) and seed yield
were affected by the ecotype and seeding rate.
Aniseed Crop, Pimpinella anisum L. is one of the important medicinal and
aromatic plants in Syria and the world. It has very important economic value,
appear in its medicinal and multi-uses. Weeds considered as the greatest
obstruct for aniseed pr
oduction and hand picking is commonly used for weed
control. So the investigation was carried out to evaluate the effect of the
herbicide, Afalon on the weeds of aniseed and its phytotoxicity. Afalon
treatment resulted in high efficacy for the broad leaves weeds (92.4 %, 97.1 %
and 96.1 %) for the half rate, field rate and double field rate, respectively and
(5.8 %, 23.9 % and 29.1 %) for the narrow weeds. The treatment of double
field rate gave a high yield (715.3 Kg/ha.) that was equal to weeded plots (777.8
Kg/ha.), and the field rate treatment (673.6 Kg/ha.) was significantly superior
to other treatment. This indicated the importance of spraying aniseed crop with
Afalon especially when hand picking not possible. Phytotoxicity effect were not
recorded on anise plants. Some other plants were not affected by the herbicide
like Ammi majus and coriander, those are belong to the same family, Apiaceae.
