Elevational patterns of Polylepis tree height (Rosaceae) in the high Andes of Peru: role of human impact and climatic conditions.

Frontiers in plant science

Kessler M, Toivonen JM, Sylvester SP, Kluge J, Hertel D.
PMID: 24847343
Front Plant Sci. 2014 May 09;5:194. doi: 10.3389/fpls.2014.00194. eCollection 2014.

We studied tree height in stands of high-Andean Polylepis forests in two cordilleras near Cuzco (Peru) with respect to variations in human impact and climatic conditions, and compared air and soil temperatures between qualitatively defined dry and humid slopes....

QTL analysis of soft scald in two apple populations.

Horticulture research

McClure KA, Gardner KM, Toivonen PM, Hampson CR, Song J, Forney CF, DeLong J, Rajcan I, Myles S.
PMID: 27651916
Hortic Res. 2016 Sep 14;3:16043. doi: 10.1038/hortres.2016.43. eCollection 2016.

The apple (Malus×domestica Borkh.) is one of the world's most widely grown and valuable fruit crops. With demand for apples year round, storability has emerged as an important consideration for apple breeding programs. Soft scald is a cold storage-related...

The effect of temperature on hairy root cultures of Catharanthus roseus: Growth, indole alkaloid accumulation and membrane lipid composition.

Plant cell reports

Toivonen L, Laakso S, Rosenqvist H.
PMID: 24201540
Plant Cell Rep. 1992 Jul;11(8):395-9. doi: 10.1007/BF00234368.

Cultivation of Catharanthus roseus hairy root cultures at different temperatures was found to have an effect on growth rate and indole alkaloid content as well as lipid composition. When lowering the temperature, the roots responded by increasing the degree...

Differences in Chlorophyll Loss at 13 degrees C for Two Broccoli (Brassica oleracea L.) Cultivars Associated with Antioxidant Enzyme Activities.

Journal of agricultural and food chemistry

Toivonen PM, Sweeney M.
PMID: 10554190
J Agric Food Chem. 1998 Jan 19;46(1):20-24. doi: 10.1021/jf970490n.

Two broccoli cultivars which have been previously found to have large differences in yellowing susceptibility were studied to determine if there was a relationship between antioxidant capability and chlorophyll loss at a simulated retail display temperature. Greenbelt cultivar retained...

Low level noble gas measurements in the field and laboratory in support of the Comprehensive Nuclear-Test-Ban Treaty.

Applied radiation and isotopes : including data, instrumentation and methods for use in agriculture, industry and medicine

Stocki TJ, Bean M, Ungar RK, Toivonen H, Zhang W, Whyte J, Meyerhof D.
PMID: 15177350
Appl Radiat Isot. 2004 Aug-Sep;61(2):231-5. doi: 10.1016/j.apradiso.2004.03.051.

Over 300 daily environmental radioxenon samples were analyzed using French developed SPALAX for automatic sample preparation including high-resolution gamma-spectrometry. The 133Xe sensitivity was significantly better than 1 mBq/m3 (specified criterion for Comprehensive Nuclear-Test-Ban Treaty verification). Radioxenon analysis was extended...

Variable Chlorophyll a Fluorescence and CO(2) Uptake in Water-Stressed White Spruce Seedlings.

Plant physiology

Toivonen P, Vidaver W.
PMID: 16665980
Plant Physiol. 1988 Mar;86(3):744-8. doi: 10.1104/pp.86.3.744.

Regulation of photosynthetic activity can contribute to the prevention of photodamage in stress resistant plants during exposure to drought or low temperatures. Responses to increasing levels of water stress were examined in seedlings of the stress resistant forest conifer,...

Wavelength modulation waveforms in laser photoacoustic spectroscopy.

Applied optics

Saarela J, Toivonen J, Manninen A, Sorvajärvi T, Hernberg R.
PMID: 19183603
Appl Opt. 2009 Feb 01;48(4):743-7. doi: 10.1364/ao.48.000743.

Different wavelength modulation waveforms were studied comprehensively in tunable diode laser photoacoustic spectroscopy. The generation of the photoacoustic signal was studied by way of simulations and experiments. A cantilever-enhanced photoacoustic detector and CO(2) sample gas were used in the...

Effects of cysteamine pretreatment and hypothalamic periventricular nucleus lesion on the cold-stimulated thyrotropin responses to intracerebroventricular 5-hydroxytryptamine in male rats.

Journal of neuroendocrinology

Toivonent M, Tuomainen P, Rauhala P, Männistö PT.
PMID: 19215378
J Neuroendocrinol. 1990 Aug 01;2(4):485-92. doi: 10.1111/j.1365-2826.1990.tb00437.x.

Abstract The hypothalamic somatostatinergic system was devitalized in male rats by intracerebroventricular (icv) cysteamine (CSH) pretreatment (250 mug/rat/day into the third ventricle) on 4 consecutive days or by a limited lesion of the hypothalamic periventricular nucleus (PeVNx). The acute...

Resonant photoacoustic cell for pulsed laser analysis of gases at high temperature.

The Review of scientific instruments

Sorvajärvi T, Manninen A, Toivonen J, Saarela J, Hernberg R.
PMID: 20059127
Rev Sci Instrum. 2009 Dec;80(12):123103. doi: 10.1063/1.3266974.

A new approach to high temperature gas analysis by means of photoacoustic (PA) spectroscopy is presented. The transverse modes of the resonant PA cell were excited with a pulsed laser and detected with a microphone. Changes in the properties...

Optical detection of potassium chloride vapor using collinear photofragmentation and atomic absorption spectroscopy.
