Predicting root biomass from branching patterns of Douglas-fir root systems
There are many examples of branching networks in nature, such as tree crowns, river systems, arteries and lungs. These networks have often been described as being self-similar, or following scale-invariant branching rules, and this property has been used to derive several scaling laws. In this paper we model root systems of Douglas-fir (Pseudotsuga menziesii var. glauca (Beissn.) Franco) as bra...
متن کاملFine root biomass and production in Scots pine stands in relation to stand age.
We determined fine root biomass and production of 15-, 35- and 100-year-old Scots pine (Pinus sylvestris L.) stands during three growing seasons. Fine roots were sampled by the soil core method. Mean (+/- SE) annual fine root biomass of Scots pine in the 15-, 35- and 100-year-old stands was 220 +/- 25, 357 +/- 21 and 259 +/- 26 g m(-2), respectively. Fine root biomass of the understory vegetati...

15 صفحه اولTree Age Effects on Fine Root Biomass and Morphology over Chronosequences of Fagus sylvatica, Quercus robur and Alnus glutinosa Stands
There are few data on fine root biomass and morphology change in relation to stand age. Based on chronosequences for beech (9-140 years old), oak (11-140 years) and alder (4-76 years old) we aimed to examine how stand age affects fine root biomass and morphology. Soil cores from depths of 0-15 cm and 16-30 cm were used for the study. In contrast to previously published studies that suggested th...
متن کاملThe effect of temperature and pH on biomass and bioactive compound production in Silybum marianum hairy root cultures
Background and objectives: The seed extract of Silybum marianum contains seven flavonolignans known collectively as silymarin. These metabolites can be produced in hairy root cultures of S. marianum. The effect of different physical factors can change root biomass and silymarin production which has been investigated in the present study. Methods<...
