In 56-day-old plants, Leucaena leucocephala and its hybrid with L. diversifolia showed 100% more total N than did L. diversifolia. Significant (P < 0.01) host-inoculation interaction in total N was 14.4% of the total phenotypic variation. The most effective and competitive Rhizobium sp. for the leucaenas was TAL 1145. Three-strain mixed inoculation was inferior to TAL 1145 alone.

Barley (Hordeum vulgare L.) leaf stripe is caused by the seed-borne fungus Pyrenophora graminea. We investigated microscopically and molecularly the reaction of barley embryos to leaf stripe inoculation. In the resistant genotype NIL3876-Rdg2a, fungal growth ceased at the scutellar node of the embryo, while in the susceptible near-isogenic line (NIL) Mirco-rdg2a fungal growth continued past the...

Changes in root organization and colonization could be relevant for wheat’s (Triticum durum Desf.) response to F. culmorum-induced crown rot disease (FCR). We investigated the biocontrol biostimulant efficiency of seeds coated with T. harzianum T-22 (T-22) four tetraploid wheat seedlings (ancient Saragolle Lucana modern Creso, Simeto, Ciclope). In an vitro experiment, repressed culmorum myceliu...

Goal. To study and to identify features of optimization crop nutrition during physicochemical degradation acid soils. Methods. Field, laboratory, computational, mathematical, statistical. Results. Results are given researches in the influence agrochemical load on gray forest soil with increasing doses fertilizers (in combination measures radical chemical reclamation without them) received 2016–...

Objective: In order to study the effect of solopotasse fertilizer on yield and essential oil of cumin medicinal plant. Methods: A experiment in randomized complete block design with three replications conducted in kermam city, Iran, in 2013. solopotasse fertilizer in four levels (0, 50, 100 and 150 kg/h) investigated. Plant height, number of umbrella per plant, number of seed per umbrella, 1000...

Mineral oil, peanut oil and soybean oil were compared with water and gum arabic for their suitability as adhesives for seed inoculation with peat inoculants. Inoculated seeds were stored at 4, 28 and 34°C, and sampled after 1, 3 and 9 days to determine the survival of rhizobia. Germination and nodulation tests were performed on the inoculated seeds. Results showed that oils were suitable adhesi...

Wild Cardon cactus seeds were inoculated with Azospirillum brasilense strains Cd and Sp-245 to improve seed germination and seedling growth parameters. Differential germination responses were related to the bacterial strain. A. brasilense Cd (the type strain for the species A. brasilense) significantly decreased seed germination. A. brasilense Sp245 (a known beneficial bacteria for cereal plant...

ABSTRACT The response capacity of the bean to fix atmospheric nitrogen is questionable, mainly due its inability supply all in flowering and grain filling phases when crop needs it most. Thus, a new application inoculant can keep population rhizobia soil at adequate levels, meeting demands plant. This study aimed investigate nodulation production beans submitted doses reinoculation Rhizobium to...

EXAMINATION OF NONSTERILE Preparation of Test Strains PRODUCTS: MICROBIAL Use standardized stable suspensions of test strains or prepare as stated below. Seed-lot culture maintenance techENUMERATION TESTS niques (seed-lot systems) are used so that the viable microorganisms used for inoculation are not more than five passages removed from the original master seed-lot. Grow each of the bacterial ...

Endophytic bacteria can promote growth and improve the quality of plant production. The objective this work was to evaluate efficiency inoculation a mix non-host endophytic isolates in nutrition tomato fruits cultivated, fertilized with rock powder different doses nitrogen. experimental design randomized blocks, factorial arrangement (2 &amp;times; 6 + 3), four replications. treatments consiste...
