The use of bark waste as a substrate in horticulture


, : The use of bark waste as a substrate in horticulture. Acta Horticulturae (37): 2003-2012

The physical and chemical properties of bark from various hardwood sources are discussed and results are presented of bioassays to test phytotoxicity to seedlings. Chrysanthemum plants in a 2/3 bark and 1/3 sand medium grew better, in terms of dry weight, where the bark was derived from Platanus and Populus spp. than in that from Celtis and Acer spp. Rooting was also faster in media containing either of the first 2 barks.

We investigated the effect of high dose methotrexate (HDMTX) therapy on plasma hypoxanthine (Hx) and uridine (UR) concentrations in 21 children with acute lymphoblastic leukemia (ALL) or non-Hodgkin lymphoma (NHL). The initial plasma Hx level befo...

The relationship between resistance to Septoria tritici blotch with plant height and heading date has been in most cases attributed to genetic associations. More efficient selection for higher levels of quantitative resistance may result if the na...

Mating initiated a pattern of prolactin secretion composed of daily surges which appeared with semicircadian rhythmicity until day 8 (day 0 = day of plug detection) of mouse gestation. On day 8, the diurnal (1500-2100 h) prolactin increase diminis...
