What is post harvest handling of cut flowers?
POST HARVEST HANDLING In agriculture postharvest handling is the stage of crop production immediately following harvest including cooling, cleaning, sorting and packing. The instant a crop is removed from the ground or separated from its parent plant it begins to deteriorate.
Why post harvest management is essential for cut flowers?
Proper harvesting and care of flowers after harvest are important to maximize the vase life and ensure a high quality product. Long before harvest, plant cultivar selection should be considered for postharvest longevity to provide the best possible cultivars for cutting.
How do you post harvest stem treatment of floral materials?
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.
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 is post-harvest practices?
Post-harvest management is a system of handling, storing, and transporting agricultural commodities after harvest. For some commodities such as coffee and cocoa, post-harvest activities may include drying and fermenting as well.
How are cut flowers harvested?
Cut flower harvesting is best done when temperatures are cool. For many gardeners, this means early in the morning. When harvesting cut flowers, place the blooms into the water bucket directly after cutting. At this time, remove all leaves from the stem that will sit below the water level of the bucket.
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.
How do you handle cut flowers?
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.
What is in cut flower preservative?
Flower preservatives use biocides like chlorine or bromine to control the growth of bacteria on the cut flowers. All flower stems have bacteria, fungi and other organisms on them. These feed on the sugar which is in the flower and then they multiply.

What is the importance of postharvest handling or operations?
The aim of the postharvest handling of locally grown produce is to deliver quality produce to the consumer. Quality cannot be improved after harvesting; therefore it is important to harvest fruits and vegetables at the proper stage, size, and at optimal quality.
How do you harvest fresh flowers?
A Peony should be cut before it opens at all, when the bud feels like a marshmallow. After harvesting, bring the buckets into a cool holding area and remove any leftover lower leaves. The stems can be recut at an angle underwater.
What is the postharvest handling of cut flowers?
This includes the postharvest handling of cut flowers. There is a short shelf-life period in which flowers stay fresh, and therefore, flowers need to be stored and transported under proper temperature levels and not around certain produce (those that emit ethylene ), as ethylene has the same effect on flowers as it does on climacteric produce.
What is the best way to harvest and care for plants?
Plants should be healthy and properly watered before cutting flowers so that the cell walls are turgid. It is important to know the optimum stage of harvesting for each plant species to ensure the quality of flowers after harvest. For maximum vase life of cut flowers, harvest flowers daily at their proper stage of development.
What are the postharvesting factors?
Postharvest factors like method of harvest, time of harvest, maturity stage, ethylene management, vase life enhancement, packaging ,storage and transportation has to be taken into account with almost care.
What happens when flowers are harvested after the optimum stage?
If harvested after the optimum stage, the developing flowers use the carbohydrates that will be used for the development of smaller flower buds, thus, slowing down the growth of other flowers. Each plant species has a minimum harvest maturity stage in which flowers can be harvested without affecting their postharvest quality.
