White poplar nursery production is mainly based on vegetative propagation hardwood cuttings. In this study the reaction of three clones of white poplar (Populus alba L.) on term of cuttings' preparation and planting according to parameters of survival and growth of rooted cuttings in three nurseries in Northern part of Serbia. There were two terms of cuttings' preparation and planting examined: a) mid-March and d) the beginning of April (standard term). Obtained results suggest considerable differences between nurseries and between examined terms. Differences between clones were not significant, but there were found significant effects of interactions of factor Clone with other two main sources of variation. The best results were obtained by cuttings that were prepared and planted in mid-March, due to faster growth and survival of rooted cuttings. The positive effect of the earlier term is evident particularly in clones L-12 and L-80 and enable feasible production of rooted cuttings of these clones, especially in nurseries that obtained better conditions. Results obtained in this study suggest that influence of terms of cuttings' production and planting is important issue concerning introduction of clones with relatively poor rooting capacity, optimization of nursery technology of experimental white poplar clones, and improvement of white poplar nursery production in general.

Abstract Stem cuttings of Ulmus parvifolia Jacq. ‘Emerald Prairie’ (‘Emerald Prairie’ lacebark elm), consisting of 7.5 to 10 cm (3 to 4 in) terminal shoot portions, were collected four times throughout the year from mature stock plants and treated with the potassium (K) salt of indole-3-butyric acid (K-IBA) ranging from 0 to 20,000 ppm (2.0%). Rooting percentages were affected greatly by K-IBA treatment and stock plant growth stage. Little to no rooting was observed without K-IBA application, whereas overall rooting for treated softwood, early semi-hardwood, late semi-hardwood, and hardwood, cuttings was 92, 86, 87, and 8%, respectively. Mean root number varied by growth stage and K-IBA concentration. Higher concentrations of K-IBA increased the number of roots on rooted cuttings except for hardwood cuttings. In general, rooting percentage and mean root number were highest at the softwood stage with 15,000 or 20,000 ppm (1.5 or 2.0%) K-IBA, resulting in 97% rooting and 15 or 22 roots per rooted cutting, respectively. However, leaf abscission was high on softwood cuttings. Semi-hardwood cuttings achieved similar rooting percentages and may exhibit better survival and growth due to greater leaf retention.

Abstract The survival and growth of yellow-cedar (Chamaecyparis nootkatensis) seedlings and rooted cuttings (stecklings) were monitored for 6 years after planting at three sites near Ketchikan in southeast Alaska to determine whether stecklings could serve as a suitable planting stock. Survival for both seedlings and stecklings was >85% at the three sites. Survival, final diameter, and final height differed by site but not by the use or absence of Vexar as protection from browsing by Sitka black-tailed deer (Odocoileus hemionus sitkensis). Vexar produced a lower rate of browsing but contributed to form problems (especially leaving trees leaning and prostrate on the ground). Seedlings had significantly greater diameters than stecklings even though they experienced a higher rate of browsing at one site. Differences in diameter and height likely were due to genetic variation rather than seedling or steckling stock type. Stecklings appear to be a suitable source of planting stock; when used for large-scale reforestation efforts, genetic considerations are essential. Planting recommendations for maximizing yellow-cedar establishment during regeneration are given.

Trees of rooted cutting and seedling origins of yellow cypress (Chamaecyparisnootkatensis (D. Don) Spach) were compared for survival and growth in two field experiments at 9 and 11 years after establishment. Experiment 1 evaluated seedlings and rooted cuttings from 1-, 3-, and 7-year-old donors. Experiment 2 compared rooted cuttings from 2-year-old donors and seedlings from the same 10 open-pollinated families. Survival was high in both experiments, with no significant differences between propagule types. In experiment 1, trees of rooted cutting origin from 1-year-old donors were significantly taller than trees of rooted cutting origin from 3- and 7-year-old donors, but there was no significant difference between trees of seedling and rooted cutting origin from any of the donor age groups. Experiment 2 found no significant differences between trees of rooted cutting and seedling origin in height or diameter, and no significant differences between families. However, in this experiment, rooted cuttings had significantly fewer multiple tops than seedlings. It is concluded that the use of rooted cuttings is a viable alternative to seedlings in reforestation of yellow cypress.

The effect of the smut fungus Microbotryum bistortarum (de Candolle) K. Vánky on Polygonum viviparum L. was investigated in the High Arctic region, Svalbard, Norway, from 2000 to 2004. Ninety-two plants in a field plot were monitored for disease occurrence, plant survival, and plant growth. The disease, initially identified in 20 plants, only spread to one additional plant in 4 years. Once infected, the plants remained infected. Although a few of the 71 uninfected plants disappeared or died without any apparent signs of disease, the majority remained healthy without smut throughout the study. The percent survival among smut-infected plants was significantly lower than that of healthy plants in 2004 (P < 0.001). The number of bulbils, the number of flowers, and the size of the largest leaves of smut-infected plants were significantly lower than those of healthy plants. These results suggest infection by M. bistortarum can negatively impact populations of P. viviparum in the High Arctic region by lowering plant growth and longevity. Teliospore surface characteristics and germination patterns of the High Arctic specimens of M. bistortarum were also documented.

The Difference

Rooting and subsequent overwinter survival and growth of single-node (5 cm; 2 in), triple-node (15 cm; 6 in), and tip cuttings (15 cm; 6in) of Acer rubrum L. ‘Red Sunset’ were compared. Triple-node cuttings had significantly more roots and total length of roots than single-node and tip cuttings, but no difference in percent rooting or percent survival existed among the cutting types. The triple-node and tip cuttings had significantly greater caliper after the first year of growth than the single-node cuttings, but the difference was minor (1 to 2 mm; 0.04 to 0.08 in). No difference in first year height existed among the cutting types. The single-node cuttings were straighter and had significantly fewer lateral budbreaks than the triple-node and tip cuttings.

Abstract Japanese Stewartia, Stewartia pseudocamellia (Maxim.), cuttings were rooted and seeds germinated to compare growth and survival of the two plant types. Softwood cuttings collected from 18-month-old, 1 to 1.3 m (3 to 4 ft) tall stock plants were rooted successfully (greater than 64%) at two propagation times by giving severed cuttings a basal quick dip in 0.1 M ascorbic or caffeic acid, before a basal quick dip in 100 ppm indolebutyric acid (IBA). Cuttings were overwintered in either a minimum heat (3C, 35F) polyhouse (89% survival), or in a 7C (45F) cooler (97% survival). There was no difference in height following overwintering, but by the end of the first growing season following propagation, seedlings were significantly taller than rooted cuttings, 84 vs 72 cm (33 vs 28 in), respectively. Although growth was vigorous, survival after upcanning was poor; rooted cutting survival was 17%, seedling survival was 48%. This study demonstrates that Japanese Stewartia can be propagated readily by softwood and semi-hardwood stem cuttings dipped in low IBA concentrations if cuttings are pre-treated with either ascorbic or caffeic acid. These cuttings can also be overwintered successfully.

Studies were conducted to evaluate container size and pretreatment on transplant survival and growth of guayule (Parthenium argentatum Gray). Seeds of cv. 11605 were planted in a greenhouse in two different container sizes. After 60 days half of the seedlings in both treatments were clipped, and then hand transplanted into the field. The height and width of 10 plants in each treatment were measured biweekly. The percent survival, date of flowering, seed germination and weight of 1000 seeds were determined. Plants produced in large containers had a higher survival rate, plant size and flowering rate. In addition non-clipped seedling had significantly higher survival rates. There were no significant differences in seed germination or in seed weights among treatments.
