Triatoma infestans, a blood-feeding insect, synchronises physiological mechanisms leading to moult with food intake. Since the corpora allata are important in moult and metamorphosis regulation, we have studied morphological changes in 4th ...
Inhibitory effect of jasmonic acid and ethylene on epicotyl growth and bud induction in the maritime pine, Pinus pinaster Soland. in ait [0.03%]
丁香酸和乙烯对木松 Pine pinaster Soland ait Maritime幼苗胚轴生长及芽诱导的抑制效应
Maria Teresa Martin,Hilda Pedranzani,Patricia García-Molinero et al.
Maria Teresa Martin et al.
Two independent parameters, epicotyl height (cm) and number of induced buds were studied on Pinus pinaster explants to analyse the effects of three phytohormones (6-benzylaminopurine, jasmonic acid, ethylene) which were combined or not in 1...
C2- and C4-position 17beta-estradiol metabolites and their relation to breast cancer [0.03%]
