| Résumé : | Two experiments were carried out for hybrid larch in 1993, indoors in a glass-house, outdoors under a shading tunnel, to compare the effect of different environmental conditions and facilities on the growth of stock plant and later on multiplication rate. Indoors, photosynthetic light increases the growth in height (+ 37 %) and the number of cuttings collected compared with natural light (+24 % NS). Outdoors under climatic cloth, the best results are with stock plants raised in containers and photoperiodic light (54 cuttings/stock plants). In the second year with stock plants transplanted into the nursery after the 1st collection, the differences due to the lighting applied in first year disappear both as regards growth in diameter and the number of cuttings collected at the 2 nd time (on average 187 cuttings/stock plant). |
