ACTIVITY OF SUCROSE DISSIMILATING ENZYMES IN EARLY ONTOGENY IN DIFFERENT FORMS OF SILVER BIRCH
Transactions of the Karelian Research Centre of the Russian Academy of Sciences, 2016 The distribution of interchangeable sucrose-cleaving enzymes’ activities in sink organs (stem, root) of silver birch (Betula pendula var. pendula) and Karelian birch (B. pendula var. carelica) seedlings was investigated.

Research of respiration of twigs and stems of the Karelian birch and Silver birch
Transactions of the Karelian Research Centre of the Russian Academy of Sciences, 2016 Stem respiration of two forms of Betula pendula Roth [Silver birch (B. pendula var. pendula) and Karelian birch (B. pendula var. carelica)] was investigated. 5-6-years old trees and 2-3-years old seedlings, grown in pots, were studied.

Boron nutrition affects the carbon metabolism of silver birch seedlings [PDF]
Tree Physiology, 2011 Boron (B) is an essential micronutrient whose deficiency is common both in agriculture and in silviculture. Boron deficiency impairs the growth of plants and affects many metabolic processes like carbohydrate metabolism. Boron deficiency and also excess B may decrease the sink demand by decreasing the growth and sugar transport which may lead to the ...

Genetic transformation of silver birch (Betula pendula) by particle bombardment [PDF]
Tree Physiology, 2000 We used in vitro callus and shoot cultures as target material for genetic transformation of silver birch (Betula pendula Roth) by particle bombardment. Cultivation of in vitro shoot cultures before particle bombardment and a long selection period, combined with a high concentration of selective agent after bombardment, led to the production of ...

Response of artificially defoliated Betula pendula seedlings to additional soil nutrient supply
iForest - Biogeosciences and Forestry, 2017 The impact of leaf damage on the growth of young silver birch seedlings with and without additional nutrient supply was investigated by simulating leaf-insect damage and applying different levels (25%, 50% and 75%) of artificial defoliation.
