Rooting Of Cuttings

Cuttings from older pines rooted more abundantly and rapidly in a growth chamber than in a greenhouse. Numerous rooting powder formulations were tested, and those containing auxins, sucrose, a fungicide, and a growth retardant outperformed those lacking one or more of these components. Best treatment combinations gave 83% rooting of cuttings from 13-year-old shortleaf pine (Pinusechinata Mill.) in 12 weeks, 100% rooting of cuttings from 12-year-old Japanese black pine (P. thunbergiana Franco) in 8 weeks, and 100% rooting of cuttings from 1-year-old slash pine (P. elliottii var. elliottii Engelm.) in 6 weeks. The most effective powder contained 1% each of indolebutyric acid, 1-phenyl-3-methyl-5-pyrazolone, and N-dimethylaminosuccinamic acid, plus 10% each of powdered sucrose and captan.

Growth of Japanese black pine (Pinus thunbergi Parl.) seedlings in containers was enhanced by incorporating a slow-release fertilizer (Osmocote) and micronutrient source in the growth medium while dolomite was detrimental. Seedlings transplanted into the field showed excellent survival, regardless of propagation treatment, however, plants grown with Osmocote and micronutrients in the container medium were significantly larger after 1 growing season. Root-to-shoot ratio was not related to survival or growth. Container-grown seedlings were larger after 3 months than 2-year-old conventional bed-grown plants and continued to outgrow the bed-grown seedlings after one year in the field.
