Evapotranspiration and water use efficiency in relation to climate and canopy nitrogen in U.S. forests [PDF]

open access: yes, 2016
Understanding relations among forest carbon (C) uptake and water use is critical for predicting forest-climate interactions. Although the basic properties of tree-water relations have long been known, our understanding of broader-scale patterns is ...

Special aspects of seed reproduction of the Liriodendron tulipifera L. in the context of plant introduction in the Ukraine’s Right-Bank forest steppe

open access: yesHortus Botanicus, 2015
It was confirmed that in order to overcome seed dormancy and to improve the seed germination of Liriodendron tulipifera L. need stratification. Seed germination of L. tulipifera is 5,2–7,4%, the execution of seeds in one fruit is 5,3–16,0%.

The draft mitochondrial genome of Magnolia biondii and mitochondrial phylogenomics of angiosperms.

open access: yesPLoS ONE, 2020
The mitochondrial genomes of flowering plants are well known for their large size, variable coding-gene set and fluid genome structure. The available mitochondrial genomes of the early angiosperms show extreme genetic diversity in genome size, structure,

Sesquiterpenes with Quinone Reductase-Inducing Activity from

open access: yesNatural Product Communications, 2009
Bioassay-directed separation of the methylene chloride extracts from the wood of Liriodendron chinense led to the isolation of six sesquiterpenes, tulipinolide (1), α-liriodenolide (2), β-liriodenolide (3), lipiferolide (4), 11,13-dehydrolanuginolide (5),

Evidence of the late lignification of the G-layer in Simarouba tension wood, to assist understanding how non-G-layer species produce tensile stress [PDF]

open access: yes, 2015
International audienceTo recover verticality after disturbance, angiosperm trees produce " tension wood " allowing them to bend actively. The driving force of the tension has been shown to take place in the G-layer, a specific unlignified layer of the ...

Distribution of First Instar Gypsy Moths (Lepidoptera: Lymantriidae) Among Saplings of Four Tree Species Common in the Great Lakes Region [PDF]

open access: yes, 2018
We examined the inter-tree distribution of first instar gypsy moth larvae under natural dispersal conditions in the field in Michigan in 1991. The study focused on saplings of northern red oak (Quercus rubra), white oak (Q. alba), red maple (Acer rubrum),
