Abstract
Rose, gladiolus and chrysanthemum flowers are the most
from Egypt.
and Beaure Gard
important commercial cut flowers exported
Mercedes Roses, Victor Borge gladiolus
chrysanthemum are the three varieties used in the present
work, they are selected varieties for exporation purposes.
This research was done at the Exp. Farm of the Faculty
of Agriculture Ain Shams University in Shoubra Al-Khemah,
the experiments were during seasons 1986-1987 and 1988.
Flowers were cut in the afternoon, then tested.
In Roses:
The average length of the cut flower was 45 ern
and the thickness of the stern was 0.08 ern and the
stem had 4 leaves. Two ems were cut from the stern
base every other day.
In Gladiolus:
The average length of the flowering stalk was 75
ern and the thickness was 0.09 to l ern and the stern
had 4 leaves, the average number of florets was 10 and
the cut of 2 ern from the stern was done every other day.
In Chrysanthemum:
The average length of the cut flower was 40 ern
and the thickness was 1 ern and the stern had 4 leaves.
Two ems were cut from the sern base every other day.
The investigation may be divided into three main points First: Export cutting stages:
l. Rose flowers:
The flowers of Mercedes Roses were harvested at the
export stage when the first two petals of the flowers started
to unfold and the buds are firm
2. Gladiois:
The flowers were cut at two stages:
1) The first stage was at the appearance of the first
sign of colour in flower at the base of the stalk.
2) In the second stage was after 2 days from the first one.
3. Chrysanthemum flowers:
The flowers were cut in 2 stages:
1. Full growth of bud and flower opening started.
2. Full growth of bud and flower opened 3 days ago,
Secondly: The Chemical Treatments:
The flowers were divided into two groups:
1. The first group was put in a refregertor for dry storage
S°C for 2 hours.
2. The second group was put in a refregerator for dry storage
S°C for 24 hours.
The flowers of each group were again divided and
exposed to the room temperature and the flowering rose stems
were placed in the following solutions:
l) The control was putting the flowers in distilled water.
2)
3)
Distilled water + 3% sucrose.
Distilled water + 3% sucrose* + 2SO ppm 8
hydroxyquinaline.
4) Distilled water + 3% sucrose + 200 ppm citric acid +
0.02% potassium chloride. 5) Distilled water + 3% sucrose + 250 ppm, 8 hydroxyquinoline
+ 200 ppm citric acid.
Gladiolus flowering stalks were placed in the following
solutions.
l. The control is tap water only.
2. Distilled water was used.
3. Distilled water + 4% sucrose.
4. Distilled water + 4% sucrose + 600 ppm, 8 hydroxyquinoline
5. Distilled water + 4% sucrose + 200 ppm citric acid.
6. Distilled water + 4% sucrose + 200 ppm citric acid +
600 ppm, 8 hydroxyquinoline.
Chrysanthemum flowering stems were placed in the following
solutions:
l. The control was putting the flowers in distilled water,
2. Distilled water + 5% sucrose.
3. Distilled water + 5% sucrose + 200 ppm, 8 hydroxyquinoline
4. Distilled water + 5% sucrose + 200 ppm, 8 hydroxyquinoline
+ 75 ppm citric acid.
Thirdly: The following data was recorded:
l. Vase life by transmitting flowers on the appearance of
the symptoms of decaying and vase life was recorded.
2. The percentage of bent neck flowers.
3. Circumference.
4. The number of the florets that opened every day.
5. The number of wilting flowers every day. 6. Mean total carbohydrate percentages. The results could
be summarized as follows:
In roses: The tested stage for roses showed a tend to flowish
and this stage can be considered the suitable
cutting stage.
In Gladiolis:
1. The proper cutting stage for Victor Borge
export
gladiolus
spikes may be the first developmental stage followed
by the second stage.
2. Total carbohydrate percentages decreased until 6 days
after cutting. Generally the first stage exhibited
higher values.
In chrysanthemum:
1. The proper cutting stage for Beaure Gard Chrysan.
themum flowers may be the first developmental stage
followed be the second stage.
2. Total carbhohydrate percentages decreased until 6
days after cutting.
3. The average circumference flower in the first stage
was bigger than the second stage.
Chemical treatments:
1. In roses:
1 . 8 hydroxyquinoline treated Mercedes roses at the
250 ppm had better marketability appearance than
the control. 2. The bent neck refflected the increased transpiration
due to high temperature during May, the percentages
of bent neck cause was 75%, while it was 10% for the
using of 250 ppm, 8 hydroxyquinoline.
3. Generally, cut flower roses lived along life in March
for about 2 weeks, then cut flower roses in April,
while the life of roses in December and May was less
than January and March.
4. As for total carbohydrate percentages treated flowers
with 250 ppm 8 hydroxyquinoline yielded higher
values followed by other treatments.
In Gladiolis:
l. The Flowers of gladiolus spikes treated with concentration
600 ppm 8 hydroxyquinoline + 4% sucrose + 200 ppm citric
acid + distilled water. These flowers gave the best
results for post harvest treatment. The average vase life
was 10 days compred with the control while was 6 days.
2. Generally, the amount of total carbohydrate percentages
during April is higher than the amount of total carbohydrate
percentages during May.
In chrysanthemum:
1. Cut flowers in bud stage and were put in solution contain:
distilled water + 5% sucrose + 250 ppm, 8 hydroxyquinoline
+ 75 ppm citric acid. resulted in flowering all the bud
flowers and last in good conditions. v
