Procurement of Chrysanthemum
Cut Flower

The Chrysanthemum (Dendranthema
grandiflorum L.) ”yellow” cut flowers were used in the
study. Flowers were harvested when the outer ray florets are completely
elongated and two rows of disc florets are completely developed. The flowers were
collected around 8.00 am prior after harvest at Busay, Cebu City flower
gallery. It was secured and packed with banana sheath, newspaper with
polyethylene to minimize weight loss and was transported to the experimental
location without any delay. This was based on DOST-PCARRD (1999).

Preparation of
Chrysanthemum Cut Flower

The chrysanthemum cut flowers were cut at an angle of 45
degrees with a sharp cutter/ scissor at 2 cm under tap water to avoid air
embolism. Flowers of the same size were selected for the experiment and the
stems were re-cut leaving about 20 cm from the flower head prior to placing
them in the treatment solutions. The foliage of the cut flowers that reached
below the waterline was removed. This is to avoid release of phenols into the
water which can block the vessels, hinder the development of the buds and accelerate
withering of the flowers. In order to achieve this, cotton was inserted to
cover the mouth of the bottles.

250mL of prepared treatment. The treatment solutions were prepared freshly and
dispensed into the bottles.
