Symbiotic Characteristics and Rhizobium Requirements of a Leucaena leucocephala x Leucaena diversifolia Hybrid and Its Parental Genotypes.
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.
متن کاملLeaf-closing substance in Leucaena leucocephala.
Potassium (2R,3R)-2,3,4-trihydroxy-2-methylbutanoate (1) was identified as a leaf-closing substance in the nyctinastic plant, Leucaena leucocephala. Compound 1 showed strong leaf-closing activity toward L. leucocephala and was not effective against other nyctinastic plants. The potassium ion was indispensable for the bioactivity of 1. Compound 1 gradually lost its bioactivity because of the exc...
متن کامل[Symbiotic efficiency and genetic diversity of the rhizobia isolated from Leucaena leucocephala in Liangshan Prefecture].
OBJECTIVE We analyzed the symbiotic efficiency and genetic diversity of rhizobia isolated from Leucaena leucocephala in Liangshan Prefecture of SichuanProvince. METHODS We studied genetic diversity of these isolates with 16S rRNA RFLP, BOX-PCR and AFLP fingerprinting, and constructed phylogenetic tree based on the concatenated sequences of the four housekeeping genes 16S rRNA, recA, atpD and ...
متن کاملSustain-Release of Various Drugs from Leucaena Leucocephala Polysaccharide
This study examines the sustained release behavior of both water-soluble (acetaminophen, caffeine, theophylline and salicylic acid) and water-insoluble (indomethacin) drugs from Leucaena leucocephala seed Gum isolated from Leucaena leucocephala kernel powder. It further investigates the effect of incorporation of diluents like microcrystalline cellulose and lactose on release of caffeine and pa...
متن کاملSteroids from the Whole Plants of Leucaena Leucocephala
Four steroids, 5α,8α-epidioxy-(24ξ)-ergosta-6,22-dien-3β-ol (1), β-sitosterol (2), β-sitostenone (3), and stigmastenone (4), along with 10 known compounds were isolated from the whole plants of Leucaena leucocephala (Leguminosae). 1, Lupeol (5), 1,3-dipalmitoyl-2-oleoylglycerol (6), methylparabene (8) and isovanillic acid (9) were found for the first time from the species. The structure of thes...
