The objective of the study was to evaluate the influence of methods for breaking dormancy the seeds of tropical forage legume Leucaena leucocephala (Lam.). The seed treatments were: (T1) water at 100 ºC/10 min; (T2) water at 100 ºC/1 min; (T3) Acetone (10 min); (T4) Ethyl alcohol (10 minutes); and (T5) intact seeds (control). Data were analyzed using a completely randomized design with eight replications, and it was adopted the Tukey test at 5% significance level. The treatment T1, had the highest speed of germination of seeds GSI, differed (P < 0.05). The T5 treatment (control) was the slowest response, that treatments that passed through some break dormancy until the seventh day after the beginning of the test (Germ7), with an amount of 20% accumulation of germinated seeds. The worst result of germination it was T5, with 30% of non-germinated seeds after 15 days of sowing.

An experiment was carried out to evaluate two temperate forage legumes (Trifolium pratense and Trifolium repens) and two tropical forage legumes (Stylosanthes guianensis and Centrosema molle) for hay intake and digestibility in the cool tropical climate of Vom, Jos, Plateau State of Nigeria. The legumes were planted in the month of June, 2016 and harvested at early-podding stage for hay. Sixteen (16) growing male New Zealand White rabbits were used for the digestibility study. The rabbits were arranged in a Completely Randomised Design and in individual cages measuring 55 cm x 39 cm x 40 cm. Nutrient contents, intake and digestibility in rabbits were determined. Crude protein content was significantly (P<0.01) higher in T. repens (18.38%) compared to T. pratense (16.50 %), whereas S. guianensis produced the least value of 13.83%. The crude fibre content of the hay was significantly higher (P<0.0I) in S. guianensis (37.29 %) compared to the other forage legumes. Dry matter intake was significantly (P<0.01) higher in rabbits fed T. repens (77.88%) compared to T. pratense (76.57%), and the lowest value of 62.97% was obtained in S. guianensis. Crude protein intake was significantly (P<0.01) higher in rabbits fed T. repens (15.05 g d-1) compared to those fed T. pratense (12.71 g d-1), but S. guianensis had the least value of 8.64 g d-1. On the other hand, rabbits fed S. guianensis hay had a higher (P<0.01) crude fibre intake (23.39%). Trifolium repens was significantly (P<0.01) higher in dry matter and crude protein digestibility (64.79 and 85. 88 %), while S. guianensis had lower values of 56.89 and 71.33%, respectively. Trifolium repens also had a significantly (P<0.01) higher total nitrogen intake and retained compared to the other forage legumes. Nitrogen retained in T. repens was 2.40 g d-1 compared to 1.87 g d-1 in T. pretense, while S. guianensis had the lowest of 1.34 g d-1. The temperate forage legume hays were higher in nutrient content, intake and digestibility compared to the tropical legume hays. Therefore, the forage crops may serve as better supplementary feeds for livestock feeding especially during the dry season.

The isolation and characterisation of a cDNA encoding a caffeic acid 0-methyl transferase cDNA homologue (COMT) from Stylosanthes humilis are described. The clone is 1391 nucleotides in length, with an open reading frame encoding a predicted protein of 366 amino acids. Cluster analysis of the deduced amino acid sequence revealed extensive homology to other published O-methyl transferase sequences. Maximum levels of homology were seen with COMTs from alfalfa (87%) and aspen (84%). Southern analysis suggested that this enzyme is encoded by two genes in S. humilis. The mRNA is most strongly expressed in stem tissue, with intermediate levels of expression in young leaves and roots, and does not appear to be induced upon fungal infection or wounding.
