Pruning Techniques

Pot-bound Tilia cordata Mill. and Salix alba L. ‘Niobe’ were planted in a Waukegan silt loam soil in June 2003 at the University of Minnesota TRE nursery in St. Paul, Minnesota. Before planting, the root balls of the container-grown plants were mechanically disrupted using one of three standard root pruning practices recommended to correct circling roots: scoring (slicing), butterfly pruning, or teasing. Root balls on the controls were left undisturbed. The trees were harvested in October 2004. Roots growing beyond the original root ball were counted and measured for diameter growth to assess the effectiveness of the root pruning techniques in encouraging root growth outside of the original root ball. All root disruption treatments resulted in increased fibrous root growth, but no mechanical root disruption method was significantly better than root balls left undisturbed.

Abstract Experimental plots measuring 2 rows (30-inch row spacing) by 50 ft were planted on 12 May in a Waukegan silt loam soil at the University of Minnesota Agricultural Research Station, Rosemount. Treatments were arranged in a RCBD with 4 replications. Granular insecticides were applied with a modified Noble applicator at planting, either banded ahead of the press wheel or in furrow. Postemergence (25 Jun) sidedress applications of liquid insecticides were made with a CO2-powered backpack sprayer at 20 gpa. Percent lodging was determined on 16 Aug. On 25 Aug, 5 roots from each plot were dug, washed, and rated using the Iowa 1-6 scale (with half-point increments for higher sensitivity).

Abstract:The development of an innovative clinical decision-support project such as the University of Minnesota’s Clinical Workstation initiative mandates the use of modern client-server network architectures. Preexisting conventional laboratory information systems (LIS) cannot be quickly replaced with client-server equivalents because of the cost and relative unavailability of such systems. Thus, embedding strategies that effectively integrate legacy information systems are needed. Our strategy led to the adoption of a multi-layered connection architecture that provides a data feed from our existing LIS to a new network-based relational database management system. By careful design, we maximize the use of open standards in our layered connection structure to provide data, requisition, or event messaging in several formats. Each layer is optimized to provide needed services to existing hospital clients and is well positioned to support future hospital network clients.

The experiment has been conducted in the nursery of the Department of Horticulture and Landscape Design, College of Agriculture, the University of Basrah to study the effect of Spraying foliar of the biostimulants Izomen and Humus on the growth and flowering of Freesia plants. The corms in similar size were planted in pots with a diameter and height of 25 cm, which filled with 2.5 kg of sterilized loam soil. After 50 days of planting, the plants sprayed with Humus at 0, 1.5, 2.5 ml L-1 and after five days sprayed with Izomen at 0, 1.5, 2.5 ml L-1 The different concentrations of biostimulants are sprayed three times, the period between one spray and another 15 is days. The results showed that the spraying of Humus at 2.5 ml L-1 significantly increased the plant height, the number of leaves and the leaf content of chlorophyll recorded (29.56 cm, 8.33 and 58.43%) respectively. Moreover, it is recorded early the flowering date (130 days), and the highest flowering mean is (2.12 inflorescence/plant) and the highest period of the remained flowers on the plant and the vase life (10 and 8 days) respectively. The effects of both Humus and Izomen were similar. In addition to the highest mean of their interaction at 2.5 ml L -1for all the studied traits.
