Earlier this yr , the Post - Harvest Knowledge Centre of FloraHolland in Naaldwijk conducted a trial to investigate how the use of dissimilar substrates affects the ledge life of Phalaenopsis . For the intention of this trial , the shelf life sentence of Phalaenopsis in 12 cm pots fulfil with different Fibre - Neth coco peat substrates was compared with Phalaenopsis grown on a ceremonious Phalaenopsis substrate .
Propagation phaseThe plants on Fibre - Neth coco peat substrate were propagated by the R&D team of Van der Knaap Group in its own innovation centre ‘ de Kas ’ in Honselersdijk . The plants on the reference substrate were propagated at a commercial baby’s room . Several Fibre - Neth coco substrates were used . Six flora were examine at the Knowledge Centre for each treatment . A number of simulation were carry out in Holy Order to test the response of the plant at different stages of refinement : the transport , full stop of sale and consumer stages . The plants were assess at the start of each level and once a week during the final degree . The cosmetic economic value of the foliation and the number of unspoiled peak were determined at the second of judgment .
ResultsDuring the course of the trial , not one works was rejected due to deficient ornamental note value or due to the flora ceasing to flower . All plants therefore had a tenacious shelf life than the 56 - day test menses . However , clear dispute in inflorescence performance and therefore quality were observed .
Overall , the standard Fibre - Neth substrate accomplish the best performance . This substrate result in the high phone number of open flowers , with scarcely any bud blast and dehydrated bud . The plants on the various Fibre - Neth substrates drop nearly no buds during the eight - week duration of the run .
The plant on the reference substrate had the most difficultly coming into flower , with a high degree of bud fire and dehydrated bud . Although the number of bud at the start and end of the trial period was higher on the reference book substratum , a high share of buds ( 72 % ) conk out to open . The different substratum did not bear on the leaf character .
