Poinsettia exposures have good outcomes...just as we thought.
The poinsettia (Euphorbia pulcherrima) is a much-maligned plant which is thought by the public and some health professionals to be extremely toxic. Despite pronouncements by public health officials to the contrary, the poinsettia continues to be recognized as a poisonous plant. To determine if there was any validity to the toxicity claims, 849,575 plant exposures reported to the American Associ...
متن کاملUsing Paclobutrazol to Control Height of Poinsettia ‘Freedom’
Late-season height control of poinsettia (Euphorbia pulcherrima) is difficult since most chemical growth retardants adversely reduce bract size when applied after first bract color. Paclobutrazol (Bonzi) controls stem elongation late in poinsettia crop development but can excessively reduce bract size if improperly applied. Two experiments were conducted to quantify how paclobutrazol applicatio...
متن کاملPhytoplasma induced changes in gene expression in poinsettia
Phytoplasma infection causes a desirable branching phenotype in the ornamental plant Euphorbia pulcherrima by releasing apical dominance. Four E. pulcherrima genes specifically regulated during phytoplasma infection were identified using differential display of cDNA-PCR products. According to BLAST searches the possible functions of the identified genes included a histidinecontaining phosphotra...
متن کاملEffect of Parasitoid Release Pattern on Whitefly (homoptera: Aleyrodidae) Control in Commercial Poinsettia
Under commercial poinsettia production conditions we compared two patterns of parasitoid release for the aphelinid whitefly parasitoid Eretmocerus eremicus Rose and Zolnerowich. We compared the currently used pattern of a fixed weekly release number (3 females per plant per week) to an experimental pattern in which more parasitoids were released early in the crop (wks 1-8), followed by a lower ...
متن کاملEffect 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...
