What are the steps to be followed after harvesting the cut flowers to enhance their keeping quality?
Precooling is a treatment given to flowers to remove the field heat immediately after harvest. It can be done with ice cold water, cold water or forced air. Conditioning/ hardening: It restores the turgor of flowers wilted after harvest, storage or transport.
How do you post harvest stem treatment?
Place cut stems into cold, well or treated water, not irrigation water which may contain bacteria. Water uptake by stems is higher with acidic water. Use an acidifying floral preservative or citric acid if your water has a high mineral content.
How do you increase the shelf life of a flower?
Change the water, clean the vase, and re-trim the stems every few days. Avoid heat, direct sunlight, windows, and even fruit: Flowers will last longer in a cooler room and if you keep them out of direct sunlight.
Why post harvest management is very much essential for cut flower and cut foliage?
Cut flower and foliage quality is at its optimum at harvest and quickly deteriorates thereafter unless product is handled correctly. It is therefore important to manage the rate of product deterioration and preserve quality for as long as possible after harvesting.
What is the most important factor in postharvest flower care and handling?
Importance of Cool Temperatures and High Relative Humidity Proper temperature management is an important factor for maintaining the quality and vase life of cut flowers. As storage temperatures increase, respiration and water loss increases and wilting occurs.
What are the different factors affecting post harvest life of cut flowers?
Cut flowers are living actively metabolizing organs and therefore, highly perishable. Four major factors during both production and postharvest stages that influence vase life are water relations, carbohydrate status, ethylene and pathogens.
Why should stems be cut at a 45 degree angle?
On an angle The first step in extending the life of your flowers is to individually cut each stem on a 45-degree angle. The reason for the angled cut is to increase the surface area, allowing the flowers to absorb more water.
What is the benefit of a slanted cut versus a straight cut?
Importance of Angled Cuts Cutting the stems at this angle, rather than straight across, allows for greater surface area and a corresponding increased water uptake. Without adequate water uptake through the stems, the cut flowers in the arrangement can lose their rigidity and droop or drop their petals prematurely.
