Experimental Embryology

Comparative morphology, biology and histology of reproductive development in three lines of Manihot esculenta Crantz (Euphorbiaceae: Crotonoideae)

“…(2007) attributed pollen abortion in Jatropha to abnormal development at the tetrad or early-pollen developmental stages . Johri (1984) described pollen abortion only before the formation of the tetrads in different dicotyledons. Pollen abortion has also been observed in other Euphorbiaceae such as Euphorbia pulcherima (Ai et al 1995) and Euphorbia dulcis (Kapil 1961).…”

Seed germination and cryostorage of Musa acuminata subsp. burmannica from Western Ghats

“…Germination of excised embryos is influenced mainly by two factors, the maturity of the embryo at excision and composition of the culture media (Johri and Rao, 1984;Uma et al, 2011). Banana embryos germinated readily on in vitro media (Asif et al, 2001;Ahmed et al, 2006).…”

Resgate in vitro de embriões em genótipos diplóides de bananeira

“…A necrose e a contaminação microbiana ocorreram em 6,13% dos embriões (Tabela 1). Este comportamento sugere adequação do método para melhorar os processos de desinfestação das sementes, de extração dos embriões, e da composição do meio de cultura (Simmonds, 1959;Stotzky et al, 1962;Johri & Rao, 1984;Darjo & Bakry, 1990).…”
