Strawberry plants of Oso Grande variety has been treated with three types
of foliar fertilizers containing (Nitrogen, Boron, Manganese) individually and
combined, in addition to treating some of them using urea as soil fertilizer.
Some plants were untreated to be used as a control. Three concentrations were
used.

This research aims to study the effect of Gebbrilin compounds, specially
GA٣, on the percentage of germination of seeds in different concentrations and
duration, Also the effect of this compound on the growth of the root cells and so
on the cellul
ar division.
It was observed from the results that these compounds had an evident effect
on the degree of germination within the low concentration, but it has an
opposition effect in the high concentrations. The results concerning the growth
of the roots are analogous to those of the germination results. An obvious
difference was in the reaction of wheat and barley to the different
concentrations of GA٣.
For the mitotic index no differences were observed compared to the control.
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.
