![]() ha-1 (2) The initial growth of black locust regeneration is quick and the young regeneration can close the canopy in 1-2 years, resulting in an appropriate dune fixation and wind erosion control (3) The young pure or mixed black locust-dominated stands are left untended until the first cleaning-respacing (mean diameter 5-6 cm), when the stand shows high stocking/density and a wide variation in tree size.Results: The main outputs of the project are as follows: (1) Black locust was established naturally by root suckers and the stocking of newly established stands can be as high as 50,000 suckers A thorough statistical analysis using the data on initial, extracted and residual trees/stands was also performed. Biometrical measurements and analyses as well as biomass estimations were performed. Materials and Methods: Three sub-compartments were selected in IV Valea lui Mihai Working Circle, Săcueni Forest District: two pure natural regenerations by root suckers of black locust at different ages (sub-compartments 3B and 52A%) and a mixed black locust - black cherry stand (sub-compartment 23D). In this respect, a Research and Development (R&D) project has been carried out in Carei-Valea lui Mihai Plain (north-west of Romania) since 2016. The seedlings can be transplanted when they are a few inches tall.Background and Purpose: The aim of this study is to highlight the importance of black locust (Robinia pseudoacacia L.), a North American-originating tree species of major importance in Romania, in extreme site conditions such as sand dunes.Water the pot regularly so that the soil is moist but not wet.Sow the seeds on the soil and cover them with a thin layer of soil.Fill a pot with a mixture of half potting soil and half sand or vermiculite. The seeds like moist, well-drained soil.Store the bag in a refrigerator for 3-4 months. Place the seeds in a plastic bag and seal it.They can be planted outdoors in the fall or winter for spring germination or they can be cold stratified to simulate winter conditions and to break their dormancy at any time of the year. Best as a hedge, screen or foundation plant or as a specimen or grouping in the shrub border. Promptly remove root suckers to control spread. Easily grown in average, medium, well-drained soil in full sun to part shade. When properly grown, this dogwood usually has few insect or disease problems. The common name refers to the cherry-like fruits which resemble in color the semi-precious gemstone carnelian (or cornelian).Ĭornus mas is noted for having excellent resistance to dogwood anthracnose and dogwood borer. They are used for making syrups and preserves. Fruits are ellipsoid, fleshy, one-seeded berries (drupes to 5/8" long) which mature to cherry red in mid-summer. Ovate to elliptic dark green leaves (to 4" long) typically develop insignificant fall color. ![]() Each umbel is surrounded at the base by small, yellowish, petaloid bracts. Yellow flowers on short stalks bloom in early spring before the leaves emerge in dense, showy, rounded clusters (umbels to 3/4" wide). It typically grows over time to 15-25' tall with a spread to 12-20' wide. Cornus mas is native to central and southern Europe into western Asia. It has a short, leaning stem and scaly, exfoliating bark. It is a deciduous shrub or small tree with a broad, rounded form and spreading branches. They stand out against the bare branches of other trees in the winter landscape. The flowers are in small clusters on the twigs. It is one of the earliest trees to bloom in the winter and it is a harbinger of spring. The Cornelian Cherry is a species of dogwood that has tiny, bright yellow flowers that profusely cover the twigs in the late winter and early spring.
