Abstract
The experiments were conducted in the Experimental
Farm of the Faculty of Agriculture at Moshtohor, Zagazig
University Benha Sector, during the Years 1982 - 1984. The
experimental design was in complete randomised block system
with four replicates.
The aim of this study was growing carnations out
doors by practicing some different horticultural treatments
(Planting date, Planting distance and Supporting). Also,
it was important to study the effects of some cytokinins
as PBA and NBA alone or combined with GA3 on the growth
and flowering qualities of cut flower carnations.
The first experiment involved the propagation critaria
and some horticultural practices as planting date - planting
distance and methods of supporting carnations.
The second experiment concerned studying the effects
of spraying different concentrations of two cytokinins namly
PBA and NBA alone or combined with GA3 on the growth and
flowering of carnations and the anatomical changes in caranations.
The most Important Results are Summerized in the Following:
1- Application of lBA at 300 ppm. followed y application
of PBA at 100 ppm. produced 100 % rooted cuttings.
2- lBA gave better results than IAA.
3- The results showed that September planting increased
the number of branches and flowers per plant and improved
flower quality, while June planting gave earlier and
longer period of flowering which is preferable for
local and forgein market supply of flowers during October
and November.
4- The results of spacing showed that the density of 30
plants/m2 was associated with the highest flower production
per unit area and the lowest number of flowers
per plant. Density did not affect flowers quality.
5- The density of 15 plants/m2 could be advised for the
best quality of Siro carnation in Egypt especially for
the exportation during winter.
6- The highest percentage of dry matter of leaves, stems
and flowers was attained from 7 and 10 plants/m2•
13- GA3 alone gave a promising effects on the number of
branches, flowers and length of internodes and flower
stems of carnation compared to control.
14- GA3 at 100 ppm. before or after PBA at 50 ppm. was
the best combination for both growth and flowering
of carnation plants and increased the fresh weights of
leaves and flower stems as well as stem length.
15- GA3 at 100 ppm. before PBA at 150 ppm. increased the
diameter of carnation flowers.
16- GA3 at 100 ppm. before or after NBA at 150 ppm. gave
the tallest flower stems.
17- GA3 increased the dry matter percentage but the cominbations
of GA3 with the cytokinin decreased it in the
leaves compared to GA3 alone.
18- GA3 slightly decreased the carbohydrate percentage.
19- GA3 applied before PBA at 100 and 150 increased the
carbohydrate percentages.
20- GA applied after PBA at all concentrations decreased
the carbohydrate percentage.
21- The anatomical studies showed that cytokinins as PBA
and NBA stimulated cell enlargement especially the
epidermal and cor1ex cells of the 4th node and increased
crystals formation and development in most tissues
For better production of cut flowers carnation
the base of cuttings are immersed in lBA 300 ppm. +
PBA at 100 ppm. for increasing the rooting of cuttings.
The plants should be transplanted in June with proper
methods of shadding. Fifteen pa1nts/m2 is a suitable
planting distance and the new method of supporting
carnation with wire mesh could be adviced and the
plants may be sprayed two times at month intervals
with GA3 at 100 ppm followed with 50 ppm of PBA for
the highest flower yield.
