datura suaveolens/atrophy

In 2009, some commercially grown tomato (Solanum lycopersicum) plants in Chiba Prefecture, Japan, exhibited mosaic symptoms. Ten plants from a total of about 72,000 cultivated plants in the greenhouses showed such symptoms. To identify the causal agent, sap from leaves of the diseased plants was

Ultrastructural features of embryogenic pollen in Datura innoxia are described, just prior to, during, and after completion of the first division of the presumptive vegetative cell. In anther cultures initiated towards the end of the microspore phase and incubated at 28 degrees C in darkness, the

If anthers of Datura innoxia containing microspores are cultured at 28° C for 24 h, two forms of haploid pollen grains are produced; one with typical unequal generative and vegetative nuclei (A), and the other with equal vegetativetype nuclei (B). The A form predominates. After 24 to 72 h in

Haploidy induction through anther culture has been examined in Datura metel and rice with a view to tracing the precise sequence of development of the pollen, either directly or through an intervening callus, into an embryo and seedling. In D. metel, the vegetative cell of the young pollen grain

BACKGROUND Datura metel contains atropine alkaloids and has been used to treat complication like asthma and, bronchitis, because of its anticholinergic properties. OBJECTIVE This study aimed to determine the prenatal effects of ethanolic extract of D. metel leaves exposure on the development of
