Étude morphologique et physiologique du rhizome du bleuet nain : une contribution à l'amélioration de la régie de culture
|Abstract:||There have been very few studies on the rhizome of the lowbush blueberry, and as such, the effects of cultural practices on that specific rhizome are unknown. Three experiments have been conducted. The first one dealt with the effects of fertilization on the rhizome and its development depending on the age of the blueberry field and the cultural cycle phase (vegetation or harvest) at four different times during the season. The second and the third experiments dealt with the impact of rhizome severing and stem pruning at different heights in newly planned blueberry fields and their density. Fertilization fostered the development of new rhizomes with a higher number of buds, but did not change their sugar content. The severing stimulated a lot of buds, and it was noticed that the segments’ regeneration potential was linked to their diameter and length. Pruning at less than 1 cm from the ground boosted stemming from the rhizome.|
