Summary1. The extent of nodulation and nitrogen fixation by a population ofHippophaë rhamnoides bushes occurring on a sand dune system on the east coast of England has been studied.2. Nodules were found on all plants (the latter ranged from 3 to 16 years in age) and using the isotope N15 it was confirmed that these nodules fixed nitrogen. The nodules on the youngest plants were most active in fixation but because of the greater total nodule mass older plants fixed the largest quantities of… 

Nitrogen fixation byAlnus viridis (Chaix) DC.

InAlnus viridis nodule growth relative to plant growth was inversely related to the quantity of nitrate added to nutrient solutions, and rate of nitrogen fixation by nodules of plants growing in the field increased with increase in altitude, a reflection of the extent to which the field sites were nitrogen deficient.

A quantitative study of nodulation inHippophaë rhamnoides L. spp.Rhamnoides in a coastal dune area

It is concluded that relatively large samples have to be investigated to obtain an impression of the nodulation of a given stand and to permit a comparison of the contribution of dinitrogen fixation in different stands.

Plant-endophyte symbiosis in non-leguminous plants

A wide taxonomic range of non-leguminous dicotyledonous plants bear root nodules and are able to fix atmospheric nitrogen, and the Alnus glutinosa endophyte has been isolated and grownin vitro in root-nodule callus tissue.

NITROGEN FIXATION BY ALNUS VIRIDIS

In Alnus viridis nodule growth relative to plant growth was inversely related to the quantity of nitrate added to nutrient solutions, and rate of nitrogen fixation by nodules of plants growing in the field increased with increase in altitude, a reflection of the extent to which field sites were nitrogen deficient in relation to climatically possible growth.

Ionic balance, proton efflux, nitrate reductase activity and growth ofHippophaë rhamnoides L. ssp.rhamnoides as influenced by combined-N nutrition or N2 fixation

Growth of 2-month-old nonnodulatedHippophaë rhamnoides seedlings supplied with combined N was compared with that of nodulated seedlings grown on zero N. Plant growth was significantly better with

Occurrence and infective potential of the endophyte ofHippophaë rhamnoides L. ssp.rhamnoides in coastal sand-dune areas

SummaryThe infective potential (IP) of nodule homogenates from field-grownHippophaë rhamnoides L. ssp.rhamnoides was determined by counting the number of nodules formed on test plants after

Nitrogen accumulation in kaolin mining wastes in cornwall I. Natural communities

The data indicate that the course of plant succession and the rate of soil development are strongly influenced by the biological properties of the colonising species and these processes are accelerated considerably following the invasion of woody legumes.

Variation in leaf nitrogen and phosphorus stoichiometry in the nitrogen-fixing Chinese sea-buckthorn (Hippophae rhamnoides L. subsp. sinensis Rousi) across northern China

The results represent a major advance in understanding the elemental stoichiometry of non-legume N-fixing plants, indicating high P and N requirements and a shift in N source from SNF to soil as temperature declines.

Biological nitrogen fixation in trees in agro-ecosystems

The integration of trees, especially nitrogen fixing trees (NFTs), into agroforestry and silvo-pastoral systems can make a major contribution to sustainable agriculture by restoring and maintaining

A Quantitative Study of Fixation and Transfer of Nitrogen in Alnus

The rate of fixation relative to the growth of the endophyte is much higher than in free-living nitrogen-fixing organisms and is clearly governed by the nitrogen requirements of the entire symbiotic system.

An Isotopic Study of the Fixation of Nitrogen associated with Nodulated Plants of Alnus, Myrica, and Hippophaë

Nodulated plants of Alnus glutinosa, Myrica gale, and Hippophae rhamnoides, the root systems of which had been exposed to excess free 15N, showed substantial enrichment in fixed 15N content in all parts of the plant, but particularly in the root nodules, supporting the conclusion already drawn that the nodules of these non-legumes are similar to those of legumes in their function and relation to the rest of the plants.

Two blue-green algae from marine environments, Calothrix scopulorum and Nostoc entophytum, vigorously fixed 15N-labelled nitrogen in artificial sea-water free from combined nitrogen and, rather faster, in natural sea- water, suggesting that these species fix some nitrogen in Nature.

The comparative treatment of the three nodulated genera represented in Europe will be based partly on new observations and partly on data already published by the authors in respect of individual species, and will not be specifically considered.

This work has found nodules on young plants of C. arborea but not on C. sarmentosa, which has long been known to be nodulated, and evidence has been produced indicating its capacity for nitrogen fixation.
