Stem cuttings of two lingonberry varieties, Koralle and Erntekrone, collected and planted in April, May, June and August, were tested for rooting and shoot growth in the presence of Trichoderma viride strain T-6-RC. Strain T-6-RC had a significant effect on increasing the rooting potential of the cuttings regardless of variety or collection date. However, this effect was more evident for Erntekrone, which generally had a poorer rooting ability than Koralle. Significant interactions between collection date, T-6-RC and variety were found for shoot growth and are discussed in the text. Key words: Lingonberry, fungi, propagation, soil micromycetes

Effects of collection date, crown position, and indole-3-butyric acid concentration on rooting and subsequent vegetative growth of softwood cuttings taken from 14-year-old Fraser fir (Abiesfraseri (Pursh) Poir.) Christmas trees were studied. Indole-3-butyric acid levels producing maximum rooting (approximately 50%) varied with crown position and date of severance. Abaxial bending during rooting was greatest for cuttings from the first collection (June 23). Increasing indole-3-butyric acid concentrations decreased abaxial bending of cuttings from the first two severance dates. One year after rooting, plagiotropism was still most pronounced on cuttings collected the first date as a result of active bending of the original cutting segment. Terminal shoot growth was greatest for cuttings from the first and third collections. Lateral budbreak was superior on cuttings collected on the first date. When all factors are taken into consideration, the best combination of rooting and vegetative growth was obtained from upper-crown cuttings which were collected just prior to lignification, wounded, and treated with 1500 ppm indole-3-butyric acid. After one season (one growth flush), rooted softwood cuttings were comparable to 2-year-old plants (two flushes) propagated by hardwood cuttings. The temporal separation of rooting from shoot extension may have been responsible for improving initial vegetative growth.

Abstract Twelve Alaska native plants were propagated from softwood and semi-hardwood stem cuttings collected from late June through August. Cuttings of new growth were treated with 0.3% indole-3-butyric acid powder and propagated in horticultural grade perlite and vermiculite (1:1 by vol) under intermittent mist with bottom heat [26C (79F)] in a greenhouse with a minimum night temperature of 15C (59F). After 6 weeks, cuttings were harvested and evaluated for rooting percentage and root quantity. Four species rooted poorly (< 25%) regardless of collection date: Siberian alder (Alnus viridis ssp. fruticosa), silverberry (Elaeagnus commutata), Bebb willow (Salix bebbiana) and shrub birch (Betula glandulosa). Best rooting (> 80%) occurred June 20 for: Beauverd spiraea (Spiraea stevenii), sweetgale (Myrica gale), and thinleaf alder (Alnus incana ssp. tenuifolia). Peak rooting for dwarf birch (Betula nana), feltleaf willow (Salix alaxensis), balsam poplar (Populus balsamifera), Labrador tea (Ledum groenlandicum) and littletree willow (Salix arbusculoides) was early to mid July. During peak rooting times, all successful species developed adequate root quantities for survival following transplanting.

&nbsp;Laboratory-produced alginate-bead inoculum of ectomycorrhizal (ECM) fungi Cortinarius sp. and&nbsp;Gomphidius glutinosus, fungal commercial products ECtovit<sup>&reg; </sup>and Trichomil<sup>&reg;</sup>, bacterial commercial product BactoFil&nbsp;B<sup>&reg;</sup>, and commercial rooting stimulator Vetozen<sup>&reg;</sup> were applied to a peat-perlite (1:2, v:v) rooting substrate of Norway spruce stem cuttings collected from 4-year-old nursery-grown seedlings immediately before the insertion of cuttings into the substrate. The application of beads free of fungi and the substrate without an additive were the other treatments. The cuttings were rooted in vessels (60 cuttings per vessel, 180 per treatment) placed in a glasshouse and arranged in a randomized complete block design. The cuttings were estimated for one growing season (approximately for 26 weeks) after their insertion into the rooting substrate. Rooting % of the cuttings ranged from 45 (mycelium-free beads) to 75 (control) according to treatments, 64 on average. No significant differences among treatments were found in % of ECM morphotypes, total ECM colonization of roots (%), and growth parameters of shoots and roots of the cuttings. The applied microbial additives were not sufficiently efficient to form treatment-related ectomycorrhizas that were formed by naturally occurring ECM fungi. Inoculation by the ECM fungus Cortinarius sp. and application of Trichomil had a partial stimulative effect on the shoot growth of cuttings. Shoot and root growth parameters were not significantly correlated with total ECM colonization, except for a negative dependence of the root number in Trichomil treatment. A higher concentration of K but lower concentrations of Ca and Mg in Ectovit treatment than in the other treatments were detected.&nbsp; &nbsp;

High Oxygen Level

Black willow (Salix nigra) stem cuttings are commonly used to stabilize eroded streambanks with survival dependent on rapid development of adventitious roots to maintain plant water balance, absorb nutrients, and provide anchorage and support especially during flood and drought events. Soaking cuttings in water prior to planting increases survival and growth rates, but it is not known whether oxygen content in the soaking water affects the rate of early root and shoot initiation and growth. A laboratory experiment tested the hypothesis that cuttings treated with high oxygen (>95% saturation, 8.62 mg O2l–-1) soaking exhibit more rapid initiation and growth of roots and shoots than cuttings treated with low oxygen (<15% saturation, 1.24 mg O2l-1) soaking and control (unsoaked). Root initiation was enhanced in both high and low O2soaking treatments compared to control (100, 93, and 41%, respectively, n = 27). High O2soaking led to greater root length than low O2soaking during the fourth week after planting (26.5 and 12.3 cm on day 22; 27.7 and 19.1 cm on day 27, respectively). Shoot growth was greater in high O2compared to low O2soaking on days 36 and 56 after planting (9.3 and 6.3 cm on day 36, 10.7 and 7.2 cm on day 56, respectively). Shoot and root biomass production was stimulated in both soaking treatments, with 200% more biomass production by day 59 compared to control. Results of this study demonstrated that a high oxygen soaking treatment has potential for improving early root and shoot growth, and survival in willow cuttings planted at riparian restoration sites.

New shoot growth of Carpinus betulus `fastigiata' was treated with stockplant etiolation and stem banding treatments and sampled for anatomical study at intervals over a 16-week period of greening following etiolation. Shading effects on the anatomy of the stem were also investigated. Numerous anatomical changes were noted with stem age and stockplant treatment. Among these were etiolation effects on the lignification of the secondary xylem, thickness of the periderm, and an increase in the percentage of sclereid-free gaps in the perivascular sclerenchyma, Stem banding increased the widths of the cortex and pith. Concomitant propagation studies revealed significant etiolation, shading, and banding effects on rooting percentages and root numbers. Using multiple linear regression methods rooting capacity was modelled best by linear combinations of the widths of the pith, non-lignified secondary xylem, cortical parenchyma and periderm, as well as the percentage of gaps in the sclerenchymatic sheath remaining non-sclerified. It is proposed that the development of sclereids in potential rooting sites reduces rooting potential. The exclusion of light during initial shoot development retards sclereid development by up to 3 months following treatment, which correlates well with observed increases in the rooting potential of etiolated and/or banded stems.

The rooting ability of GF677 peach rootstock by hardwood (H), semihardwood (SH), and softwood (S) stem cuttings collected January, February, May, and November, treated with various IBA concentrations—0, 500, 1000, 2000, and 3000 ppm—was studied. H cuttings collected in January and treated with 2000 ppm IBA caused significant increase in rooting (62%–5%). In addition, the SH cuttings prepared February and treated with 1000 or 2000 ppm IBA gave 42.5%. The May experiment resulted in low rooting percentage where H cuttings treated with 500 ppm IBA gave 10% rooting. In October, SH cuttings with 1000 or 3000 ppm IBA gave the highest rooting percentage (60%), while in November 90% rooting was obtained in H cuttings treated with 3000 ppm. Regardless of type of cutting, IBA at 1000, 2000, or 3000 ppm was better for rooting the GF677 than at 500 ppm. However, irrespective of IBA concentration, H and SH cuttings gave significantly high rooting percentages. On the other hand, best rooting was obtained when the stem cuttings of GF677 (regardless of wood type) were collected in November. Wounding base of the cutting of GF677 improved rooting ability.
