In agriculture, post harvest handling is the stage of crop production immediately following harvest, including cooling, cleaning, sorting and packing. Post-harvest treatment largely determines final quality, whether a crop is sold for fresh consumption, or used as an ingredient in a processed food product.

The most important goals of post-harvest handling are to keep the product cool, to avoid moisture loss and slow down undesirable chemical changes, and avoiding physical damage such as bruising.

Initial post-harvest storage conditions are critical to maintain quality. Each crop has an optimum range for storage temperature and humidity. Also, certain crops cannot be effectively stored together, as unwanted chemical interactions can result.

Various methods of high-speed cooling, and sophisticated refrigerated and atmosphere-controlled environments, are employed to prolong freshness, particularly in large-scale operations. 

Vase Life of cut flowers:  

A fresh flower is still a living specimen even though it has been cut from the plant. The vase life of cut flowers decline due to the following reasons.

  • Inability of stems to absorb water due to blockage
  • Excessive water loss from the cut flower
  • A short supply of carbohydrate to support respiration
  • Diseases
  • Ethylene gas
  • Room temperature and humidity

Preservatives are used to extend the vase life of cut flowers. Floral preservatives are very effective in maintaining quality and extending longevity. We can have almost double vase life by using preservatives in water as compared with no preservatives.

Floral preservatives perform three functions:

  • Provide sugar (carbohydrate).
  • Supply a bactericide to prevent microbial growth and blockage of the water- conductive cells in the stem.
  • Acidify the solution

Some of the preservatives used in floriculture are:

  • Aluminium Sulphate (Also4)
  • T.S. (Silver Thio Sulphate) Solution
  • Chlorine: Chlorine it is added 20 mg/liter.
  • Rvb Chrysal : Rvb Chrysal preservative is used @ 2 ml/liter. Every bucket containing 5 to 7 liters water. We should add 10 to 15 ml of Rvb Chrysal.
  • Florissant: Florissant buffer stock solution of 8 liters is prepared by adding 1 liter of Florissant and 7 liter water. Later added to every bucket containing 5 to 7 liter water. Florissant is available in a convenient pack of 1 litre, 5 litres, 10 litres, 25 litres and 200 litres.

Water should be treated with any of the above mentioned preservatives and then flowers should be put into the bucket.

Vase life testing laboratoryVase life testing Procedure :

Testing vase life of flowers is nothing but checking the life of harvested flowers from the day of harvest to the final drooping after full open. Following steps are to be followed.

  1. Take two containers or glass bottles named containers A and container B.
  2. Container A container pure water with EC < 0.5 and pH – 5.5 to 7.
  3. Container B contains water and preservative in desired quality.
  4. The quantity of water should be half of the container size. Generally the height of the container should be 30 to 40 cm and diameter around 10 to 15 cm.
  5. Select two stems of same length, bud size, bud opening of the same variety. Cut the bottom of the stem 1 cm and keep in the containers.
  6. Keep the stems in containers.
  7. Everyday cut the bottom of the stems by 4 cm and keep it again in the same container.
  8. Every alternate day replace water and water with preservative.
  9. The experiment should be carried out at room temperature and normal humidity with enough light.
  10. Continue the procedure till both the stems are fully open and get dropped.
  11. Count the number of days since the start of experiment and that is the vase life of the flowers. Such experiment should be carried out for different varieties in different seasons.

1. Post Harvest Operations of Rose

Post harvest operations for rose

1. Harvesting :

Harvesting is the last but not least operation is the greenhouse. Harvesting should be done at right stage and right time. Harvesting should be done by skilled labour

2. Pre Cooling Chamber :

The Buckets contains 70 - 80 stems are shifted from greenhouse to pre cooling chamber at an earliest and kept at 8 – 120C for at least 2 hours. This is done to remove field heat and extend the storage life of flowers.

Roses cold storage

Cold storage for Rose

3. Deleafing :

The leaves from the lower portion of the stem are removed upto 15 cm to reduce the weight of the stem. All infected leaves are also removed. The disposal of the leaves from the Deleafing machine area should be done frequently. The rubber brushing should not be too hard as it may damage the stem.

4. Grading:

The grading of flowers should be done according to the stem length, bud size, stem thickness and opening of flowers. In manual grading, skilled workers are used for grading. Bent neck, thorn damage flowers, disease and pest affected and thick stem should be rejected.

5. Sorting and Bunching:

Criteria for sorting of flowers as follows -

  • Sorting should be done according to local and export market requirement.
  • Thickness of the stem should be uniform in a bunch.
  • All the buds in a bunch should have same opening stage.
  • Bunching is done according to buyers requirement viz staggered or level head bunching.

2 Japan 10 Level head
3 Europe 10 Level head

6. Cold Chain :

It is very important to maintain the same cut stage of flowers the post harvest operations right from harvesting in the field upto the flower reaching to the market. If the temperature is not maintained properly the flowers may open and the price is reduced to a great extent.

Hence the temperature in the post harvest chain is reduced to minimize the activities in the stem. The temperature is reduced during post harvest as follows:

Table: Cold chain temperatures at different stages

S.No. Location Temperature Minimum Holding Time
1 Green house at  the time of harvest 24°C Immediately
2 Packing room 18°C One Hour
3 Pre cooling 8°C to 12°C Two Hours
4 Cold storage  0°C to 2°C Two Hours
5 Reefer Van  0°C to 2°C  

7.  Packing

Step No. 1.

After bunching the flower heads are wrapped with white or brown coloured wrappers. The size of the wrappers depends upon the bud size and number of flowers per bunch.

1 40 3 20 X 35
2 50 3.5 20 X 40
3 60 4 20 X 45

Step No. 2.  

Two rubber bands (2” or 4”) are placed below the bud and at the bottom of stems to avoid loosing of stem or wrapper during transport. 

Step No. 3.

The size of the packing box varies with the stem length, number of stem and distance of the destination where the flowers are to be sold. Generally 3 ply corrugated paper box is used for domestic market and 5 ply corrugated paper box is used for export purposes.

 A printed corrugated box carries following information

  •  On top side of the lid “Fresh cut flower “is printed.
  • On width wise side of the lid “Variety, number of stems, stem length, box number is written on both sides.
  • On length wise side of the lid “Fresh cut flower and handle with care is written on both sides.”
  • Senders and buyers address with phone number.

Step No. 4.

Bunches are packed in 5-ply boxes in such a way that flower heads face in opposite direction. Bunches should be placed in a row along the length of box. The second layer is placed opposite to the first layer. 

Step No. 5.

Each layer of bunches is covered with soft paper.

Step No. 6.

Once bunches are placed properly in a box strapping is done, the box is closed with the lid and strapped properly. The stem should be tightly held in the boxes so that they are not subject to jerk movements during transport.

Step No. 7.

The boxes are kept in cold storage at 0 – 20C till dispatch.

Reefer Van fortransport of cut flowers8. Transport

A common rule should be followed “first in, first out” i.e. first arrived flowers from green houses should be processed and dispatched first.

Reefer van containers are generally used to transport cut flowers for export. These vans transport the produce from the production center to the airport and to the concerned market.

0°C to 2°C temperature is maintained inside the reefer van.
