Schreurs' New 2016 Rose Mutation Variety Introductions
Schreurs are proud to introduce to the market new rose varieties for 2016. The following four mutations are among the additions made to the larger Schreurs assortment. This detailed infomartion on the four new mutations is vital for rose growers in Africa.
Marry Haiko!
It’s characterized by a medium head size with unique Bi- color (orange/Red) & nice deep green leaves. To achieve this characteristics, the variety should be grown under clear plastic. It belongs to one family with Marie Claire! and Mariyo! We prefer to start with proper bending (double bending) for more production. Blossoming cycle (Flush to flush) of Marry Haiko! is 57-55 days’. Stem length of 50-70 cm can be achieved.
Once harvested in the field, short & long stems should be separated in different buckets to avoid damages while transporting it to the pack house. The variety opens very well with a vase life of between 10 – 14days. Presentation on vase life as well as in the bucket is very attractive.
Pests & Diseases
We have experienced no issues with pests or diseases. The variety doesn’t appear to be susceptible to either downy mildew or botrytis even though our pesticide sprays have been minimal. It all depends on who the grower is.
Cut stage
The cut stage adopted will be partially dependent upon the market being supplied & the buyer’s preference. We believe that our best cut stage for the auction is about the size of 5 Kenyan shilling coin, for the direct market is about the size of 10 Kenyan shilling coin and for bouquet (a bit open) is about the size of 20 Kenyan shilling coin. However, Marry Haiko! opens & performs well in the vase from any cut stage 10-14 days.
Marry Haiko! Post-harvest
Post harvest is important and we have taken great care in trying-out several post-harvest solutions. Our solution is made up of Calcium Hypochlorite and Aluminum Sulphate. Calcium Hypochlorite provides Chlorine which acts as a disinfectant and acidifier. Disinfection is the treatment of the water to inactivate or destroy pathogenic bacteria, fungi, viruses, cysts, and other microorganisms. The aluminium sulphate acts as a flocculant. Flocculation is a process where colloids come out of suspension in the form of flocs or flake thus purifying the water. The water purification process starts first prior to disinfection and acidification. In a tank of+- 200 liters of water we add+- 144g of the aluminium sulphate stir it well and let it sit. The flakes are then decanted out, then we add 5g of calcium hypochlorite stir the solution well and measure the pH which should be about 4.5-4.8.
GRADING
From the field, the product is well monitored in terms of time harvested the quality and the time taken from the greenhouse to the intake. Here the product is then held in the cooler for atleast 4hrs and ready to be graded. At the grading hall Marry Haiko! is distributed to the measuring tables, then sorted in terms of length, ready to be supplied to the graders who then grade the best quality. Immeditely after this the product is taken to the dispatch house and held overnight ready to be packed in the morning.
PACKING
After grading the Marry Haiko! crop is packed per length (40, 50, 60, and 70) using different pack rates as follows:
Length pack rate
- 40 cm 350 stems
