2. Dependent variables determined. The vase life of gladiolus cut flowers was determined by containing the number of
florets open, length of stem, diameters inflorescence, number of stems whit the
physiological disorder bent neck after 5and 10days., was also recorded change carbohydrate
in leaf and petal flower although instrument content chlorophyll in leaf Soluble
carbohydrate were extracted from leaf an petal (days 1, 5, 10) 0/25 gr chopped material of
periapt tissue was fixed in the ethanol, the material was macerated and centrifuged
(3500x,10min) the supernatants were pooled and use for the estimation of carbohydrate.
Carbohydrate were estimated by the method of paving and leachier (1979) using
Anton as standard soluble proteins were extracted from leaves(1, 5, 10 days) and petal in an
extraction buffer (0.01Mtris-HCL) and protein assay was carried out according to method of
Bradford, content chlorophyll in leaf: At each stage (1, 5,10 d) 0/5 gr chopped material of
periapt tissue was fixed in water ionize, the tissue was homogenized in 10 ml acetone the
material was macerated and centrifuged (3500x,10min) the supernatants were pooled and
use for the estimation of, Absorbance of extracts were measured using a WAPS 105
spectrophotometer according to (ausati1980) the leaf chlorophyll content was determined as
absorbance of these extracts at 663 and 645 nm (ausati1980). The following equation was
used to calculate the relative total chlorophyll content (ausati1980).
