“…Nodule fresh weight was lower on both levels of stress for Carioca, with decreases of 52% and 60% for five and eight day stresses, respectively ( Table 1). Saito et al (1984) also observed a sharp decrease in nodule fresh weight for cultivar Carioca under two levels of water stress. Nodule fresh weight in EMGOPA-201 was not affected by stress treatment.…”

“…After being harvested, plants were dried at 65 o C and grounded for determination of N concentration, using a Analyzer (Model 1106). Leaf water potential (LWP) was measured in the youngest fully most expanded leaf, using a pressure bomb (Scholander et al, 1965). Relative water content was measured in one leaflet just below the youngest expanded leaf.…”

-The aim of this work was to investigate the effect of water stress on N 2 fixation and nodule structure of two common bean (Phaseolus vulgaris L.) cultivars Carioca and EMGOPA-201. Plants were harvested after five and eight days of water stress. Carioca had lower nodule dry weight on both water stress periods; shoot dry weight was lower at five days water stress and did not differ from control after eight days stress. Both cultivars had lower nitrogenase activity than control after five and eight days water stress. For both cultivars, after eight days stress bacteroid membranes were damaged. Carioca presented more pronounced damage to infected tissue, with host cell vacuolation and loss of the peribacteroid membrane at five days after stress; at eight days after stress, there was degradation of cytoplasm host cells and senescence of bacteroids, with their release into intercellular spaces. Intensity of immunogold-labeling of intercellular cortical glycoprotein with the monoclonal antibodies MAC 236/ 265 was different for both cultivars.Index terms: Phaseolus vulgaris, nitrogenase, leaf water potential, nodulation. Efeito do estresse hídrico na fixação biológica de nitrogênio e estrutura de nódulos de feijãoResumo -O objetivo deste trabalho foi investigar o efeito do estresse hídrico na fixação biológica do N 2 e na estrutura dos nódulos de feijão (Phaseolus vulgaris L.), nas cultivares Carioca e EMGOPA-201. As plantas foram colhidas após cinco e oito dias de estresse hídrico. A cultivar Carioca apresentou menor peso seco de nódulos que o controle (plantas irrigadas). O peso da parte aérea seca da cultivar Carioca foi menor aos cinco dias de estresse hídrico e não diferiu do controle, após oito dias de estresse. As duas cultivares tiveram menor atividade da nitrogenase após cinco e oito dias de estresse hídrico e apresentaram danos na membrana peribacteróide após oito dias de estresse. A cultivar Carioca foi mais afetada do que a EMGOPA-201, com vacuolação das células e perda da membrana peribacteróide após cinco dias de estresse; aos oito dias, houve degradação das células do citoplasma, senescência e liberação dos bacteróides nos espaços intercelulares. A intensidade de glicoproteínas nos espaços intercelulares do córtex, marcada com os anticorpos MAC 236/265, foi diferente nas duas cultivares de feijão.Termos para indexação: Phaseolus vulgaris, nitrogenase, potencial de água na folha, nodulação.

“…An extended period of stress during the vegetative stage retards nodulation and depresses N 2 fixation (Abdel Ghaffar et al, 1982;Saito et al, 1984;Zablotowicz et al, 1981). Once the nodules are established, desiccation results in decreased N 2 fixation (Pankurst and Sprent, 1975), and it drops to near zero when nodule moisture content is reduced to 50 or 55%.…”

Most dry bean production in Mexico is under non-irrigated conditions in the semi-arid highlands. One of the most limiting factors is insufficient moisture during the reproductive stage and sometimes during the vegetative stage. The objective of this experiment was to study the effect of drought on nodulation, N z fixation and grain yield of beans. The cultivars evaluated were: Flor de Mayo Bajio, Bayocel, Bat-477 and Honduras-35. The treatments were water stress treatments during vegetative or reproductive stage and a control of minimal stress. To measure N 2 fixation, lSN-labelled fertilizer was used. Data for soil moisture, nodule number and nodule dry weight, as well as, straw and grain yield and total N were taken. The results indicated that water stress during vegetative stage depressed nodulation temporarily, but after watering regularly plants not only recovered completely but were nodulated better than the control. Water stress during the reproductive stage depressed nodulation and after watering there was no recovery. Grain yield was not affected by water stress during vegetative stage but it was reduced when water stress was imposed during the reproductive stage. The percentage of N derived from fixation varied among cultivars but was not affected by water stress treatment. The highest N 2 fixation occurred in Bayocel and Bat-477 and the lowest in Honduras-35 and F.M. Bajio, although the amounts were not as low as in some other reports.

“…3 also shows that lucerne plants can support a minimum sitona weevil population density of about 1000/m 2 during drought. Saito et al (1984) observed that nodule weight of Phaseolus vulgaris plants in dry soil is about 10-20% of that in wet soil. Observations suggest that lucerne behaves in a similar way (Goldson unpublished data).…”

The relationship between maximum potential soil moisture deficit (D max.) during Sitona discoideus Gyllenhal oviposition and subsequent peak larval establishment in young lucerne (Medicago sativa L.) is described. Regression analysis showed that variation in larval establishment from year to year was best correlated with the values of D max. attained during September and October. The best fit was hyperbolic, implying a precipitous reduction in peak larval numbers when D max. exceeded about 50 mm. After this reduction, larval populations were stable at about 1000/m2. This pattern is probably a result of rhizobial nodule availability for neonate larval populations. The eventual size of larval populations is related to the prevailing soil moisture conditions in September-October. This period has previously been found to be the most important for sitona weevil egg-laying within New Zealand, in terms of resultant larval establishment.
