TLDR
The results obtained from various laboratory and field studies with respect to the allelopathic effects of pine and details of isolation of allelochemicals from pine materials are reported here.Abstract:
The allelopathic potential of red pine (Pinus densiflora), pitch pine (Pinus rigida) and black pine (Pinus thunbergii) has attracted attention of Korean botanists for the last several years. It has been a point of interest why the understorey species are sparse (Lee and Monsi, 1963) and species growing there were similar with the other pine understoreys. It was hypothesized that the similarity of floristic composition of pine stands was caused by some regulating mechanism controlled by pine through the release of certain toxic substances (allelochemicals) in the soil. When the greenhouse soil was mixed with pine leaves, the growth of the plants was suppressed. However, the toxicity of the soil was gradually reduced, and ultimately diminished after several years. This further strengthened the idea of the possible release of allelochemicals by pine. Therefore, it deemed necessary to verify experimentally whether pine is indeed producing allelochemicals which, in turn, affect neighbouring plants. For this, several experiments were performed involving various species growing inside and outside the pine forests. The results obtained from various laboratory and field studies with respect to the allelopathic effects of pine and details of isolation of allelochemicals from pine materials are reported here.read more

Potential allelopathic effect of Pinus halepensis in the secondary succession: an experimental approach
Catherine Fernandez,Benjamin Lelong,Bruno Vila,Jean-Philippe Mévy,Christine Robles,Stéphane Greff,Sylvie Dupouyet,Anne Bousquet-Mélou +7 more
TL;DR: The allelopathic potential of Pinus halepensis Miller, which is known to synthetize a wide range of secondary metabolites, could influence plant succession through allelopathy through the release of potential allelochemicals in the environment by leaf leachates or root exudates.

TL;DR: It is shown that autotoxicity is a potential functional process that could influence natural regeneration of P. halepensis, but field conditions studies are necessary.
Allelopathic interactions in forestry systems.
Ravinder Kumar Kohli,K. Sassa +1 more
TL;DR: A survey of the available information reveals that most of the agroforestry species (AF species) have negative allelopathy effects on food and fodder crops as discussed by the authors, therefore, it is desirable to do further research in this direction so that AF species with no or positive allelopathic effects on the companion crops may be promoted for agro-forestry programs.

Allelopathic effects of Pinus halepensis and Quercus coccifera on the germination of Mediterranean crop seeds
TL;DR: Germination responses were generally different between cereals and legumes where cereals tend to be less affected by allelopathic influences than legumes, especially fababean, which is suggested to be a leading alternative for food security and forest conservation.

Control of pitch pine seed germination and initial growth exerted by leaf litters and polyphenolic compounds
TL;DR: Investigating the influence of three concentrations of water extracts of three leaf litter species (pitch pine, huckleberry and white oak) and a mixture of all litters on the germination of pitch pine seeds and initial seedling growth in a microcosm experiment concluded that these phenolics are not allelopathic to pine seedlings.

Inhibition of nitrification by climax ecosystems
Elroy L. Rice,Sunil K. Pancholy +1 more
TL;DR: The results indicate that the nitrifiers are inhibited in the climax so that ammonium nitrogen is not oxidized to nitrate as readily inThe climax as in the successional stages.

Inhibition of nitrification by climax ecosystems. ii. additional evidence and possible role of tannins
Elroy L. Rice,Sunil K. Pancholy +1 more
TL;DR: It appears that the tannins and tannin derivatives may play a continuous and rather prominent role in the inhibition of nitrification by vegetation.

TL;DR: The identity of some of the compounds produced as well as their relative phytotoxicity to lettuce seed and seedlings were determined by using paper, thin-layer, and gas chromatography as mentioned in this paper.

Allelopathic effects of juglone on germination and growth of several herbaceous and woody species
TL;DR: Based on the effects on seedling shoot elongation and dry weight accumulation, the five species found to be most sensitive to juglone were Lonicera maackii, Lespedeza cuneata, Trifolium incarnatum, Alnus glutinosa, and Elaeagnus umbellata.
