Incorrect planting depth is another primary cause of poor seedling survival. For bareroot seedlings the root collar (soil surface line when the seedling was in the nursery beds) must be located at the soil surface when finished.

The experiment was monitored for twelve months, and then harvested. The following parameters were evaluated: height (H), ROOT COLLAR diameter (D), dry matter of aerial part (MSPA) and root (MSR), total dry matter (MST) and seedling quality indexes H/D, H/MSPA, MSPA/MSR and IQD were calculated.

The response of lodgepole pine (Pinus contorta Dougl. var. latifolia Engelman.) seedlings to three levels of soil compaction and water content was evaluated in raised beds filled with a sandy clay loam soil. In compacted soils, seedling survival, height, ROOT COLLAR DIAMETER and root growth were reduced. Soil water regime was adjusted with irrigation to levels associated with plant moisture stress (near wilting point) and limiting soil aeration (near 0.10 m3 m–3 air-filled porosity). Soil water regime affected SEEDLING performance, with higher survival, ROOT COLLAR diameter and root growth observed on treatments with higher water content.

Les auteurs ont évalué la réaction des plantules de pin tordu (Pinus contorta var. latifolia Engelman) à trois degrés de compactage et teneurs en eau du sol sur des planches de semis surélevées remplies de loam d’argile sablonneuse. Le taux de survie, la hauteur de la plante, le DIAMÈTRE DU COLLET et la croissance des racines diminuent avec le compactage. On a ajusté le régime hydrique par irrigation afin d’obtenir la teneur en eau qui correspondait au stress hydrique pour l’espèce (près du stade de flétrissement) et on a réduit l’aération du sol (porosité de près de 0,10 m3 d’air par mètre cube de sol). Le régime hydrique affecte le rendement des PLANTULES avec une hausse du taux de survie, du diamètre du COLLET et de la croissance des racines quand l’apport d’eau est plus élevé.
