“…Host X strain interaction contributed significantly to the observed variation in dry weight, N content and DW/N ratio, but this source of variation was less important quantitatively than the additive effects of host cultivar and Rhizobium strain (Tab, 1), Strain differences accounted for the largest effects on N content and DW/N ratio, whereas the largest effects on dry weight were due to cultivar differences. The presence of interaction confirms results obtained with other legumes such as alfalfa (Erdman and Means 1953, Gibson 1962, Tan 1981, clover species (Nutman 1954, Mytton 1975, Smith et al, 1982, cowpea (Minchin et al, 1978) and field bean , The results of such experiments, however, depend on the choice of host and strain genotypes as emphasized by Smith et al, (1982) and Dean et al, (1980). It is also illustrated by the work of Mahon (1979) and Hobbs and Mahon (1982) on pea genotype and Rhizobium strain effects on CjHj reduction activity, Mahon (1979) found no interaction, whereas Hobbs and Mahon (1982) observed significant interaction when other host X strain combinations were used.…”

The symbiotic performance of four pea (Pisum sativum L.) cultivars in combination with each of four strains of Rhizobium leguminosarum was studied in growth chamber experiments in order to estimate the effects of cultivars, strains and cultivar × strain interaction on the variation in dry weight, N content and dry weight/N ratio. At harvest 63 days after planting, cultivars accounted for 75% of the variation in dry weight, while the Rhizobium strains accounted for 63% of the variation in N‐content and 70% of the variation in dry weight/N ratio. Cultivar × strain interactions were statistically significant, but of minor quantitative importance, accounting for 5–15% of the total variation. Rhizobium strains also influenced the partitioning of N between reproductive and vegetative plant parts and between root and shoot biomass.

“…Intermediately effective strain 008 produced the largest amount of variability and the most likely improvement in average productivity would be obtained therefore, if plant selection were carried out in relation to this intermediate strain. Nutman (1954) has already shown a good response to selection in red clover with an intermediately effective rhizobium strain.…”

The effects of mixtures of rhizobium strains on the dry matter production of S. IOO white clover were investigated by growing plants in tubes of agar with four pure strains known to give contrasts in yield effectiveness, and comparing the results with those produced by plants grown with mixtures of these strains, and with those of uninoculated plants receiving mineral nitrogen. It was found that some components of the mixtures influenced yield much more than others and these strains therefore appeared to be strong competitors. Ability to infect and capacities to f u nitrogen were

“…По-третє, рослина визначає кінцеву ефективність симбіотичної азотфіксації. Так, у конюшини виявлено два гени, що сприяють утворенню неефективного симбіозу незалежно від властивостей використаного штаму бульбочкових бактерій [33]. По-четверте, бобова рослина, як і бактерії, бере участь у синтезі леггемоглобіну бульбочок [34] Розроблена технологія має широкомасштабне впровадження.…”

Статтю присвячено проблемі біологізації сільськогосподарського виробництва, зокрема питанням біологічного азоту, ролі мікроорганізмів у поповненні його запасів у ґрунті та підвищення продуктивності рослин завдяки використанню бактеріальних препаратів. Розглянуто внесок українських учених у вирішення цієї проблеми, зокрема, представлено розроблену ними екологічно чисту технологію отримання рослинного білка на основі використання симбіотичної взаємодії високоефективних мікроорганізмів із сучасними сортами бобових рослин. Доведено економічний ефект від впровадження вказаної технології у виробництво.
