plumsteadia pedicellata sp nov a new glossopterid Fructification from la golondrina formation guadalupian lopingian santa cruz province argentina
Review of Palaeobotany and Palynology, 2009Co-Authors: Barbara Cariglino, Pedro R Gutierrez, Marcelo Jorge ManasseroAbstract:Abstract A new specimen of glossopterid Fructification – Plumsteadia pedicellata – from the Permian of La Golondrina Basin, in Santa Cruz Province, Argentina, is described. The Fructification has ?ovule scars, and is attached to a Glossopteris leaf. This represents the first Argentinean record of glossopterid Fructification in organic connection with its leaf, as well as the first record of Plumsteadia for Argentina.

Fructification diversity from the la golondrina formation permian santa cruz province argentina
Geobios, 2013Co-Authors: Barbara CariglinoAbstract:Abstract The Permian ([?]Late Cisuralian-Lopingian) outcrops of the La Golondrina Formation (Santa Cruz, Argentina) are known for their abundant and diverse fossil flora, including Gondwanan and Euramerican elements. However, of all the groups represented, Fructifications have only been recognized for a few glossopterids and sphenophytes. This study describes and reviews 11 taxa from both specimens housed institutionally and recently collected, comprising a total of 14 fertile morphotaxa recognized in the La Golondrina Formation (excluding pteridophytes). In addition to their systematic description, hindrances to identification related to the fragmentary nature and sparse occurrence of the Fructifications are discussed. The La Golondrina Formation hosts the highest known number of Fructifications and greatest diversity amongst Permian basins in South America, reaffirming its status as one of the most diverse floras of that time.

influence de la provenance du geniteur et du type de pollen sur la Fructification sous pollinisation controlee chez dacryodes edulis burseraceae au cameroun
International Journal of Biological and Chemical Sciences, 2012Co-Authors: J T Makueti, Z Tchoundjeu, Antoine Kalinganire, B A Nkongmeneck, E Asaah, Alain Tsobeng, A KouodiekongAbstract:Tres peu de travaux ont ete realises sur l’amelioration varietale des especes locales. L’amelioration de leur germoplasme aboutit a l’obtention du materiel vegetal ameliore destine a la creation de nouveaux cultivars. Des essais de pollinisations croisees controlees ont ete menes sur Dacryodes edulis dans le but d’evaluer l’influence de la provenance des geniteurs et du type de pollen sur la Fructification de 14 accessions femelles issues de 03 provenances. Les croisements ont ete effectues selon un schema en bloc imbrique. Pour chaque croisement effectue, le nombre de fleurs pollinisees, le nombre de fruits noues et le nombre de fruits arrives a maturite ont ete evalues; le taux de nouaison (TN), l’indice de Fructification (IF) et le taux de chute des fruits (TC) calcules et soumis a une analyse de variance. A partir des moyennes obtenues, les differentes combinaisons ont ete classees en fonction de leur performance a l’aide du ‘cluster analysis’. Les resultats obtenus ont montre que l’indice de Fructification qui determine le rendement de l’espece etudiee varie uniquement et de maniere significative ( p=0,010 ) sous l’action combinee des trois facteurs etudies. Six meilleures combinaisons caracterisees principalement par un taux de nouaison, un taux de Fructification eleves et un faible taux de chute de fruits apres nouaison (plus de 70%, plus de 50% et moins de 20% respectivement) ont ete identifiees. Les graines des fruits (hybrides F1) issues de cette etude ont ete caracterisees et les plants ont ete produits en pepiniere. Ces derniers serviront de materiel de base d’un essai clonal dans un futur proche. Mots cles : Banque de genes, essai clonal, germoplasme, safoutier, pollinisation controlee
