R. A. Vorob'ev, D. N. Teben'kova The Main Pigment Content in Needles of Introduced Spruce in the Southern Taiga (Niznhii Novgorod Region) // Forest Science (Lesovedenie). 2013. No 4. С.22-31. The data on the content of the main pigments in the 1- and 2-year-old needles of introduced spruce (Picea L.) trees growing at the Botanical Garden of the Lobachevsky Niznhii Novgorod State University are presented. The significant variability of the chlorophyll and carotinoid contents in the needles testifying to different rates of forming their pigment pool was found. Success of introducers' adaptation was assessed according to pigment characters. The hereditary pattern of steadily displaying differences between the introduced species by the content of the main pigments in needles was revealed. The data obtained provide the possibility to include indices of the pigment composition into a complex of characteristics for assessing prospects of the study species introduction. Needles, introducers, photosynthesis, photosynthetic activity, pigments, spectrophotometry, chlorophyll a, chlorophyll b, (a + b) chlorophyll, chlorophyll a/chlorophyll b (ab-1), carotinoids. |
