Black locust was introduced in Hungary between 1710 and 1720. The first large black locust forests were established at the beginning of the 18th century on the Great Hungarian Plain stabilizing the windblown sandy soil. In the country, black locust occupied 37.000 ha in 1885, 109.000 ha in 1911, 186.000 ha in 1938 and 415.000 ha in 2009. At present, it is the most widely planted species in Hung...

A solubility-insolubility transition assay was used to screen the bark and stems of seven leguminous trees and plants for self-aggregatable lectins. Novel lectins were found in two trees, Robinia pseudoacacia and Wisteria floribunda, but not in the leguminous plants. The Robinia lectin was isolated from coexisting lectin by combined affinity chromatographies on various sugar adsorbents. The pur...

Elderberry (Sambucus nigra) and black locust (Robinia pseudoacacia) agglutinins, which are abundantly present in the bark of both species, display seasonal fluctuations with regard to their content in this tissue. These seasonal changes result apparently from a circa-annual rhythm of lectin accumulation and depletion during autumn and spring, respectively. Because the bark of trees can be consi...

A new species is described, Xorides benxicus Sheng, sp. n., reared from the cerambycid twig-boring pest of Robinia pseudoacacia Linnaeus, Pterolophia alternata Gressitt, 1938, in Benxi County, Liaoning Province, China. A key is given to the species similar to Xorides benxicus Sheng, namely Xorides asiasius Sheng & Hilszczański, 2009, Xorides cinnabarius Sheng & Hilszczański, 2009 and Xorides sa...

In the study were presented data for comparison of antibacterial activities between long time stored acacia (Robinia pseudoacacia L.), multifloral and oak (Quercus spp.) honeydew honeys towards Staphylococcus aureus (ATCC 9144). The results showed that the antibacterial activity of oak honeydew and multifloral honeys was much higher in comparison with acacia honeys with the lowest antibacterial...

To evaluate the applicability of leaf and canopy photosynthesis models, we compared performance of 6 leaf models and validated 1 canopy model of photosynthesis based on field data of black locust (Robinia pseudoacacia L.) plantations on a Loess Plateau in northern China. Leaf photosynthetic light response curves and diurnal canopy photosynthetic rates were observed in the field in August 2009. ...
