Silver Maple

Several commercially available Acer saccharinum and A. negundo taxa were established with 10 single-plant replications in a cultivar trial at the TSU–NCRS in 1993 and 1994. Each plant was fertilized in spring and early summer with 100 gm 15–15–15 beginning Summer 1993. Drip irrigation was applied as needed beginning Summer 1993. Vegetation within tree rows was controlled with preemergent and postemergent herbicides, while grassed middles were mowed. Growth data were recorded in Fall 1993 and 1994 and height and caliper increment calculated for the 1994 season. In the silver maple group with most height growth were: `Silver Queen', `Skinneri', and `Silver Pyramid'. These differed significantly from a group of four slower growing cultivars. Cultivars with the most height growth also had the most caliper growth. Seedling boxelder grew faster than one accession of `Flamingo', while three other cultivars were intermediate. Data will also be presented on insect and disease ratings.

Commercially available Acer saccharum cultivars, and some closely related species accessions (floridanum, leucoderme, macrophyllum, and nigrum `Greencolumn'), were established as 10 single-plant replications in a cultivar trial at the TSU–NCRS in 1993 and Spring 1994. Plants were regularly fertilized and drip irrigation was begun Summer 1993. Growth data were recorded each fall and height and caliper increment calculated for the 1994 season. In the group with most height growth were: `Bonfire', `Majesty', nigrum `Greencolumn', leucoderme, `Sweet Shadow', `Fairview', and macrophyllum. These, except for `Fairview' and macrophyllum, differed significantly from a group of seven slower growing cultivars. With some exceptions, cultivars with the most height growth tended to have the most caliper growth, while those with the least height growth tended to have the least caliper growth. Data will also be presented on insect and disease ratings.

Commercially available Acer rubrum and A. freemanii taxa were established as 10 single-plant replications in a cultivar trial at the TSU–NCRS in 1992 and Spring 1993. Plants were fertilized regularly and drip-irrigated as needed beginning Summer 1993. Growth data were recorded each fall and height and caliper increment calculated for the 1994 season. Ten cultivars were in the group with most height growth: `Armstrong', `Autumn Blaze', `Schlesingeri', `Olson', `Morgan', `Scarlet Red', `Embers', `Indian Summer', `Scarsen', and `October Glory'. These all differed significantly from a group of 11 slow-growing cultivars. With some exceptions, cultivars with the most height growth tended to have the most caliper growth, while those with the least height growth tended to have the least caliper growth. Data will also be presented on insect and disease ratings.

Ten single plant replications of 11 taxa were planted 6 May 1994, fertilized regularly, and maintained under drip irrigation. Japanese beetle damage became apparent in mid-June. Sevin SL at 1 qt/100 gal was applied with a tractor-mounted mist blower on 22 June, and 7 and 19 July. Data on Japanese beetle populations were recorded using an arbitrary scale of 0 (no beetles) to 10 (heavy infestation). Damage on each tree was recorded using an arbitrary scale of 0 (no damage) to 10 (completely skeletonized). The annual increment in height and caliper growth was recorded for each tree in Fall 1994. Ulmus japonica and U. glabra `Pendula' had the most height growth (>60 cm increment) but were not significantly different from most other accessions, while NA 60070, U. crassifolia, and NA 60071 had significantly slower growth than the former group(<25 cm increment). Japanese beetles fed first on U. carpinifolia `Variegata', NA 60071, and 60070, skeletonizing most of the new growth before the first Sevin application, resulting in the most damage. This may have resulted in poor growth of the USDA/NA selections in 1994.

Heavy Infestation

In Florida, clustered pellitory is becoming a troublesome weed for citrus, especially from the winter through early summer. Inadequate management of this weed can result in its heavy infestation in tree rows and can interrupt the spray pattern of low-volume drip irrigation systems. This new 3-page publication of the UF/IFAS Horticultural Sciences Department will assist Florida citrus growers with proper identification of clustered pellitory and with adoption of adequate and timely strategies to manage this weed in their groves.

Maple Seed

Abstract Silver maple shows promise for use in short-rotation intensive culture energy plantings. A seed source study composed of trees from 26 midwest locations was established in south-central Nebraska in 1979 to determine where silver maple seed should be collected for use in the central Great Plains. Trees were evaluated for survival, height growth, and number of dominant stems per tree during their seventh growing season. Sources from eastern Nebraska, western Iowa, eastern Kansas, and northwest Missouri generally exhibited the greatest survival, height growth, and number of dominant stems. Height growth appears to be under stronger genetic control than stem number, suggesting that selection for height should take priority when selecting trees for biomass production. Geographic trends related to survival and height growth, but not stem number, were observed. Environmental or geographic factors that are strong predictors of seed source performance could not be identified. Planting the most locally produced seed is advisable for the central Plains. North.

Transpirational Water Loss

Effects of SO2 on transpiration, chlorophyll content, growth, and injury of woody angiosperm seedlings were studied during the first few weeks after germination. Fumigation of silver maple (Acersaccharinum L.) and black locust (Robiniapseudoacacia L.) seedlings with SO2 at 0.75 ppm for 2 to 16 h increased transpirational water loss. As duration of fumigation was increased, the effect of SO2 on increasing transpiration declined. Leaves of silver maple seedlings fumigated with SO2 at 0.75 ppm for 8 to 16 h were injured; those of black locust were not. In another experiment, the adverse effects of SO2 were greater on black locust than on American elm (Ulmusamericana L.) seedlings. Fumigation of young black locust seedlings with SO2 at 2 ppm for 1 or 4 h significantly reduced chlorophyll content, height growth, dry weight increment of roots, and leaf formation. Leaf injury symptoms appeared within 24 h after fumigation with 2 ppm SO2 for 4 h. Fumigation of American elm seedlings with SO2 at 0.5 or 2 ppm for 0.5 to 4 h decreased dry weight increment of roots but did not injure plants or significantly influence chlorophyll content, height growth, or leaf dry weight. Inhibition of dry weight increment of roots was a more sensitive indicator of susceptibility to SO2 than was reduction in dry weight increment of shoots.

Water crisis is assuming a more explosive and dangerous phenomenon due to stiff competition and demand between domestic use and agricultural activities. Farmer friendly and affordable indigenous water harvesting structure was developed and evaluated for the Farming systems research citrus expansion orchard at the National Horticultural Research Institute, Ibadan. The structure, made of bamboo materials and polyethylene sheets was constructed to harvest rainstorm and stored in plastic reservoirs between September and October 2007. The aim was to apply the water for drip irrigation of young citrus seedlings during the dry months of November until the on-set of rainfall. Six thousand litres of water were harvested. Drip irrigation system was connected to the rainstorm harvester to facilitate application of water to the young citrus seedlings planted at 7m by 5m spacing. Water application at the drip rate of 2.4 l/hr was done in split-plot fitted into randomized complete block design at one, twice and thrice per week with three replications under four fertilizer sources (poultry, horse, cow manures and urea fertilizer). Base line growth data for citrus at the initial watering stage stands at 139 for number of leaves, 83.5 cm for plant height, and 12.3 mm for stem diameter. Watering thrice per week under poultry manure was found to produce the best growth parameters. Generally, the structure was discovered to be cost effective, water saving, adoptable and affordable by farmers with little or no maintenance or educational background.
