Characterization of Hybrid Poplar Clones for Resistance to the Forest Tent Caterpillar
Forest Science, 1994Abstract Forest tent caterpillar, Malacosoma disstria Hbn., behavioral and developmental interactions with 15 hybrid Populus spp. clones were studied in laboratory and glasshouse trials. Significant differences in larval preference and performance among the clones were found. Larval development time ranged from 30 to 52 days.

Length of cuttings in juvenile development of a hybrid poplar clone
New Forests, 1991The influence of length of cuttings on establishment of a short rotation plantation was investigated over a period of two years using direct field planting of unrooted Populus “Rasumowskiana” cuttings. The longer the cuttings, the higher were the survival and dry mass production.

Plasmids, pCA1 and pCWEA1, carrying antimicrobial peptide gene(s), Ac-AMP1.2 and ESF12, were used to transform hybrid poplar clones Ogy and NM6. Peptide Ac-AMP1.2 is an analog of Ac-AMP1 which is one of the smallest chitin-binding proteins. Synthetic peptide ESF12 mimics the amphipathic α-helix found in magainins.

Variation in diameter of central columns of discoloration in six hybrid poplar clones
Canadian Journal of Forest Research, 1976The percentage of stem diameter discolored in the center of hybrid poplar logs varied by clones. For the six clones studies, discoloration columns ranged in percentage of total stem diameter from 85.0 to 55.8.

Clone by isolate interaction in the hybrid poplar – Septoria musiva pathosystem
Canadian Journal of Forest Research, 2008Fourteen clones of hybrid poplar were inoculated with 19 isolates of Septoria musiva Peck under greenhouse conditions to determine the magnitude of the clone, isolate, and clone × isolate interaction effects. Septoria musiva isolates were collected from five geographic areas, two symptoms (canker and leaf spot), and two host types (native species and ...

Damage caused by the poplar-and-willow borer, Cryptorhynchus lapathi (L.) (Coleoptera: Curculionidae), is reported to vary among hybrid poplar clones. We evaluated oviposition preferences and larval success in four hybrid poplars on potted and field-planted trees.

A comparison of pre-planting treatments on hardwood cuttings of four hybrid poplar clones
New Forests, 2003Rooting and early growth of four hybrid poplar clones (Populus spp.) planted in a greenhouse were examined after applying 40 pre-rooting treatment combinations to dormant cuttings. Treatments included 2 cutting lengths (5 and 10 cm), 5 soaking times (0, 2, 4, 8, and 12 days), and 4 dips (chitosan, rooting hormone powder, liquid rooting hormone added to
