This paper deals with an evaluation of the economics in two commercial plum orchards which were established between 1993-1997 using dense tree-spacing and modern principles of orchard management. This evaluation was conducted in 1994-2004 with the following cultivars: Bluefre, Common Prune, Čačanska lepotica, Čačanska najbolja, Gabrovska, Hamanova, Opal, President, Ruth Gerstetter,Stanley, and Valjevka. Orchard establishment costs, pruning costs, annual orchard operating and pest management costs and returns up to 11 years of growth are given. A denser planting had a positive influence on total yields per hectare with higher returns. Costs per ton...

The kiwifruit cultivar Hayward was grafted on three-year-old seedling rootstocks of the same cultivar in field conditions. Inverted T-budding, chip-budding, conventional local T-budding by hand and chip-budding with manual grafting unit were used as budding types. All budding operations were done on the 15th May in 2002 and 2003. The hand chip-budding gave the highest bud-take (98.34%), sprouting rate (91.67%), shoot diameter (6.84 mm) and shoot length (58.07 cm). The manual chip-budding grafting unit also performed well but it was more time consuming and gave lower graft success.

In the years 1999-2004 the propagation technology of winter grafting was studied in five oak taxa: Quercus frainetto, Q. macranthera, Q. pubescens ssp. anatolica, Q. virgiliana and Q. robur Fastigiata. These species are suitable for the needs of intravilan revitalization and for various types of landscape. The yield (%) of one-year-old oak grafted plants (X/1/0) was evaluated in percentage by the portion of saleable grafted plants. In the year 2004 the yield of 75 to 97% was achieved. According to the numbers of young grafts (X/1/0) at the heights 15-30 cm, 30-50 cm, 50-80 cm it was possible to asset the...

Citrus is grouped under the salt sensitive crops. Mycorrhizal fungi, a symbiotic relationship between plant roots and beneficial fungi, are supposed to impart the stress tolerance in the host plants. The stress tolerance improved due to Arbuscular Mycorrhizal fungi (AM fungi) colonization can be attributed to enhanced mineral nutrition. In the present study the efforts are made to evaluate the effectiveness of AM fungi with two citrus genotypes under salt stress. Three-month-old seedlings of Karna Khatta (Citrus Karna) and Troyer Citrange (Poncirus trifoliata × Citrus sinensis) were inoculated with the indigenous soil based AM inocula...
In vitro selection of salt tolerant Morus alba and its field performance with bioinoculants

Hort. Sci. (Prague), 2006, 33(2):77-86 | DOI: 10.17221/3743-HORTSCI
In vitro selected salt tolerant saplings of Morus alba (cv. Sujanpuri) were raised from nodal explants with axillary buds collected during three different periods of the year. The growth and shoot/root multiplication of the nodal explants collected between November to February and July to October were found to be better than those collected between March to June. In cultures, shoot multiplication was induced by the application of 2.5 mg/l of 6-benzylaminopurine (BAP) and 0.3 mg/l of gibberellic acid (GA3), while rooting by 1.0 mg/l of indolebutyric acid (IBA). Sodium chloride (NaCl) was added to induce salt stress and its...
