  Picto médicinalThis species is listed in the French Pharmacopoea

Harvest is done on the ground or directly on the tree.

Maturity signs of the fruit : From green, it turns blackish and swells.

Protocol : None in particular.

Harvest period: April to May.

Harvesting in natural environment : Quite delicate because of the relative scarcity of the species and of their location which renders difficult serene harvesting (individuals usually found on the edge of rocky cliff). However, the seed-growers generally produce many seeds. 12 trees were harvested during the LIFE+ COREXERUN project.

Post-harvest Handling : Avoid letting the fruit get dry and do removing its pulp.

Number of seeds per fruit : Most often 4.

Germination Rate : 9 % (rate between 0 and 83% depending on the lots).

Duration before the first day of germination : 45 to 90 days

Age before transplanting  : 60 to 80 days..

Problems / Observations during culture :

  •  germinations very spread out over time ;

  •  Mineral deficiency rapidly visible (foliage turns yellow) ;

  •  Be cautious during weaning as the plants dry out easily  ;

  •  Rapid growth : 8 to 10 months

Mortality rate after transplanting  : 29 %.

 

Dynamic Stage : unknown.

Number of plants reintroduced : 787.

Mortality rate after planting : High – the first season (42 %) to low the second season (10 %). The high mortality recorded in the first season is probably due to excess water since there were heavy rainfall, especially during the time when the species were planted.

Mortaliy rate 1 year after planting : Very high, 57 to 69 % depending on the season.

Average growth 1 year after planting : 22 cm in height and 10 cm at the level of the ring.
