Transmission of Branch-inducing Phytoplasma PoiBI from Poinsettia (Euphorbia pulcherrima) to Crown-of-thorns (E. milii)

Transmission of Branch-inducing Phytoplasma PoiBI from Poinsettia (Euphorbia pulcherrima) to Crown-of-thorns (E. milii)

Phytoplasma PoiBI is responsible for free branching in poinsettia (Euphorbia pulcherrima Wild. ex. Klotzsch). In this study, PoiBI was transmitted by dodder from poinsettia to crown-of-thorns (E. milii Des Moulins) in one out of ≈100 attempts, whereas grafting transmission was unsuccessful. PoiBI was shown to be viable in E. milii, as it was detected in the recipient plant and in its cuttings o...

Photodegradation of the molluscicidal latex of "crown-of-thorns" (Euphorbia milii var hislopii).

Study of the embryofeto-toxicity of Crown-of-Thorns (Euphorbia milii) latex, a natural molluscicide.

The crude latex of Crown-of-Thorns (Euphorbia milii var. hislopii) is a potent plant molluscicide and a promising alternative to the synthetic molluscicides used in schistosomiasis control. The present study was undertaken to investigate the embryofeto-toxic potential of E. milii latex. The study is part of a comprehensive safety evaluation of this plant molluscicide. Lyophilized latex (0, 125,...

Effect of Salicylic Acid on Rooting of Poinsettia (Euphorbia Pulcherrima)

The poinsettia's species name pulcherrima means "most beautiful" and that it is! Poinsettia's brilliant red floral display held against rich green foliage has made this unlikely species a holiday favorite. Its appealing presentation of the traditional Christmas colors has so endeared poinsettia that it is now second only to the Christmas tree as the most popular holiday plant. Studies have show...
