The Cananvalle rose farm in Ecuador uses ReduFlex Blue against darkening of the petal . This make unnecessary a set of labour . moreover , they harvest longer stems and the glasshouse climate is more pleasant to work in .
In many countries , red roses have a deeply symbolical value . For this rationality , perfect looks are more authoritative for them than for other species of flowers . After all , you would n’t give someone a present that was less than stark . This is why blacken of the petals on crimson cultivar form a major obstruction to sales , even if the prime is otherwise unblemished .
In the eighties Israeli research worker delved into this take . Their studies unwrap that UV radiation was behind it and that down in the mouth temperature made the trouble worse . However , if you contend to block out the UV radiation therapy in effect , any temporary dusty temperatures no longer touch the heyday .
ultraviolet illumination in plastic greenhousesIt is therefore unsurprising that the trouble occurs peculiarly in plastic greenhouses . This is because , unlike trash , plastic allows UV to pass through it . For this understanding , young films that feature a ultraviolet radiation blocking agent are now available , although they run to degrade over sentence . This means the nursery cover permit more and more ultraviolet radiation light in and the blackening issue exasperate .
The Cananvalle come up farm in Ecuador was suffering this trouble with the Freedom variety . ‘ Although we usually only regard blackening to the edge of the petals , it occasionally affect the whole flower . In decree to preclude this happening , we enveloped each rosebud with a minor charge plate net to protect it from UV radiation . This signify a raft of extra work , ’ explains Arturo Salazar .
block UV effectivelyMardenkro recommended trying out ReduFlex Blue to tackle the subject . The coating was primitively developed for the role of reducing the portion of blue air in the PAR light . However , readings in Mardenkro ’s own laboratories showed that ReduFlex Blue also barricade out about the whole ultraviolet light spectrum ( 250 - 400 nm ) .
‘ From July 2017 onwards we tested ReduFlex Blue on 2500 m2 . Since we have the same climate all year round , the coat stay intact . We took care to guarantee the layer was applied very uniformly , ’ says Salazar .
‘ We are really enthusiastic about the results . Not only has the issue of darkening been powerfully boil down , but we are also seeing longer stems . Together these effects are improving output . The semblance of the peak is also good , ’ he conclude .
Better working conditionsAn additional benefit is that the staff discover work in the coated greenhouse more pleasant . It is a short cooler in there than it used to be . The cause for this is that ReduFlex Blue also blocks heat ( near - infrared ) radiation . ‘ We are very felicitous with the results and so far we have n’t escort any drawbacks . For this reason we are going to apply ReduFlex Blue to a larger area and with other diverseness , ’ says the manager of the endeavor .
Another arise farm in Ecuador has since been enjoying similar experiences with ReduFlex Blue as well .
