The present investigation was carried out on the experimentally-induced mutations with gamma rays on the seeds of Verbesina encelioides Benthem and Hooker. Ionizing radiations altered the mean total seed germination and also temporal patterns of the germination when compared with control. Higher doses were deleterious for most of the seed parameter...

Cytogenetical and molecular studies in Argemone mexicana Lin. (2n = 28) and A.ochroleuca ssp. ochroleuca Sweet. (2n = 56) showed exclusive bivalent pairing at meiois; their triploid hybrid had, univalents, bivalents and trivalents; autotetraploid of diploid A. mexicana had bivalents and quadrivalents and polyhaploid of A. ochroleuca showed bivalenc...

Variable leaf segments of Verbesina encelioides exhibited different responses when cultured on MS supplemented with 0.5 mg/l BAP. With the addition of IAA/NAA to the basal medium completely inhibited the formation and growth of callus. Endogenous content of IAA in the different segments of the leaf when assayed revealed that middle segment had high...

... It was observed that the young leaf of V. encelioides did not produce callus to the same extent as the middle segment of the leaf did in MS medium containing BAP + NAA/IAA and BAP without any addition of auxins (Karnawat et al., 2010). In our study, middle pieces of leaves (L2) showed higher callus induction capacity than basal pieces of leaves with its petioles (L1). ...

[20] Kingdom: Plantae Subkingdom: Traqueobionta Superdivision: Spermatophyta Division: Magnoliophyta Class: Magnoliopsida Subclass: Magnoliidae Order: Papaverales Genus: Argemone The genus Argemone is originating from America, currently with presence in different countries outside its natural range of distribution. Karnawat [21] mentions that the genus comprises about 30 species. According to Ownbey [19,22], there are 23 species in North America, highly distributed throughout Mexico and Central America, with the exception of very high areas, generally around 2400 meters above sea level. ...
