| TEST # 4 with CHITOSAN on FRUIT PLANTS | ||
| We are now testing our transpiration reducing
solution of CHITOSAN and plastic bags on the most fragile hence the
most difficult to ship tropical plants : the tropical fruit
plants.
( of the size that we ship them )
|
A week before staying in cartons all the plants
were sprayed with CHITOSAN and the roots were dipped in a gel
containing beneficial organisms ( several fungi types, some lactic
acid bacteria and an hormone-like acid). They stayed 6 days bare
roots in cartons at tropical temperature in large closed plastic
bags that maintained a high level of humidity. ( the leaves were cut
off to reduce transpiration further )

On day 7 when opening the plastic bags, while
almost all these fruit plant species have lost their leaves,
they are potted in a moist soil and entirely closed with plastic
bags. We let them stay in their individual closed bags 3
weeks ( so without watering ) the outside temperature being from
27 to 34 Celsius, we are in the rainy season although rains have now
stopped the air is still very humid.

The results are shown by the pictures, they are quite surprising : we were not expecting they would be so good as such fruit plants are known to die so easily !
|
After these 3 weeks in pots + 6 days bare roots
= 27 days in individual closed plastic bags all plants
are alive, with new buds and small leaves on all, even if parts of some
plants show attacks, sometimes hard, by adverse fungi and rot.
