The seed plant used by tribal and rural people our country as a source edible oil. present investigation Niger deals with study back cross-program improvement variety. Unknown local variety (A) niger was selected non-recurrent parent because having some desirable characters like less vegetative growth (d...

The effect of pre and post-anthesis shading (20% of incident radiation) on pericarp development, cotyledon cell number and seed growth dynamic of fruits from three positions in the capitulum (peripheral, mid and central) of two sunflower (Helianthus annuus L.) genotypes were studied at two locations. Both shading treatments reduced pericarp weight, fruit volume and total yield per plant. Plants...

Lychnophora pseudovillosissima, a new species from the State of Minas Gerais, Brazil, is here described and illustrated.

BACKGROUND AND AIMS The reproductive biology of Syngonanthus mucugensis and S. curralensis (Eriocaulaceae) was studied in areas of 'campo rupestre' vegetation in the Chapada Diamantina, north-eastern Brazil. These species are herbaceous and the individuals have a grouped distribution. Their leaves are united in a rosette, and their inflorescence is monoecious, of the capitulum type. The stamina...

Senecio changii (Asteraceae: Senecioneae), a new species from Muli, Sichuan, southwestern China, is described. It is distinguished in Chinese Senecio s.s. by having lyrate-pinnatisect to pinnatisect leaves and a single terminal large discoid capitulum which is somewhat nodding. Evidence from floral micromorphology, karyology and molecular phylogenetic analyses based on the nuclear ITS/ETS seque...

This article deals with the mechanism of production and the method of reduction of injuries of the lateral condvlar epiphysis of the humerus. These injuries are usually described as affecting the capitulum, but, as noted by Roberts (1936) and Watson-Jones (1943), the detached fragment consists of the capitular epiphysis and the lateral third of the trochlea with a fragment (common to all epiphy...
