EFFECT OF CHEMICAL FRUIT THINNING 0F SAMANY DATE PALM CULTIVAR. [PDF]
The effect of fruit thinning using ethephon and cytophex at different concentrations and dates of application was studied on Samany date palm cultivar in two seasons (2003-2004). Fruit set percentage was much decreased when ethephon was sprayed at all

Translocation of Ethephon in Beans and Peas1
Abstract Translocation of (2-chloroethyl) phosphonic acid (ethephon) was studied in 14-day old bean plants ( Phaseolus vulgaris L. cv. Black Valentine) and 7-day old pea seedlings ( Pisum sativum L. cv. Alaska).

Reactive oxygen species, antioxidants and the regulation of plant development
The regulation of axillary bud outgrowth by the interplay between phytohormone and redox signals. Axillary bud outgrowth is regulated by cellular energy status and the balance between phytohormones, notably abscisic acid (ABA) and gibberellic acid (GA).

Effects of Ethephon on Olive Ripening1
Abstract Solutions of (2-chloroethyl) phosphonic acid (ethephon) at 1000, 1500, and 2000 ppm were sprayed on trees of ‘Giarraffa’ olive ( Olea europaea L.) time midway between the onset of pit hardening, and the maximum respiratory rate induced early pigmentation of drupes ...

Three closely linked X‐chromosomal genes potentially control sex determination in Cannabis sativa
Summary Sex determination mechanisms in dioecious plants remain poorly understood yet offer an excellent model system to study genetic changes underlying morphological evolution. We investigated the genetic basis of sex determination in Cannabis sativa, combining quantitative trait locus mapping in a segregating population, comparative transcriptomics ...

Scientific Opinion on waiving of the dog studies in the regulatory process of agrochemicals approval
Abstract Commission Regulation (EU) No. 283/2013 sets out the data requirements for pesticide active substances and includes short‐term oral toxicity testing in rodents (90‐day rat study) and non‐rodents (90‐day dog study) to support human health hazard assessment for pesticide active substances in the European Union (EU). However, the relevance of the
