Improvement of black locust (Robinia pseudoacacia L.) growing under marginal site conditions in Hungary: case studies
Published June 30, 2018
129-133

In Hungary, black locust (Robinia pseudoacacia L.) is considered as an important exotic stand-forming tree species growing mostly under unfavourable ecological conditions for forest management. Due to climate change effects, its importance is increasing in many other countries, too. As a result of a selection programme, new black locust clones ...were tested in clone trials. Juvenile growth of 12 micropropagated black locust clones in two plots series established at different dates were evaluated in central Hungary under marginal site conditions. At age of 7 the clone R. p. ‘Bácska’ (‘KH 56A2/5’), at age of 10 the clones R.p. ‘Homoki’ (‘MB17D3/4’) and ‘PV201E2/4’ appeared to be especially promising for mass production. Based on the data obtained from the performed trials, it can also be concluded that tissue culture can be considered as a suitable tool for propagating superior individuals and offers new prospects for the rapid cloning of selected genotypes used for plantation forestry.

Micropropagation of Leuce-poplar clones and its role in selection breeding
Published March 23, 2016
43-48
Leuce-poplars (mostly white poplar and its natural hybrid grey poplar) are native tree species trough Hungary. They are covering more than 4.0 per cent of the Hungarian forested area (77 000 ha). The white (grey) poplars play a significant role in the forestation under sandy soil site conditions as well as they are of importance from nature c...onservation point of view as well.
Long-term selection breeding work is going on at the National Agricultural Research and Innovation Centre Forest Research Institute (NARIC FRI), involving selection of fast-growing Leuce-poplar clones under dry site conditions.
Micropropagation technology is relatively quickly spreading in forestry. In vitro multiplication of trees is applied mainly in fruit growing in Hungary, in case of forestry it is used mainly for selection breeding.
This paper presents a short overview on the micropropagation trials with different Leuce-poplar clones and the early evaluation of the seedlings growing of the micropropagated clones/varieties.

Comparative research of the Wild Sage (Salvia nemorosa L.) population and selected clones flowering biology

...5); font-variant-ligatures: normal; font-variant-caps: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">The collected and evaluated of morphological Salvia variants widespread application provides for a new type of hungaricum series create. The excellent drought and frost tolerant Salvia nemorosa L. is climate change-tolerant perennials include. At the right time carried out with the new propagation cutting method can be shortened the seedling time, because in 1 year from broke cuttings develops flowering population. The flowering period of Salvia during one vegetation period may extended with right fertilization and phytotechnical, so it becomes suitable for planting in public spaces.
