a pot experiment was conducted in a completely randomized design with five treatment and five replication, in each replication were 6 plants used. the study of zinc sulphate (znso4) application (20 and 40 ppm) and salicylic acid (sa) application (50 and 150 ppm) was compared to the control (distillated water) on growth and flowering petunia hybrid. for each plant was used 100 cc of solution at ...

Thanks to the rapid progress in molecular biology of flavonoid biosynthesis and plant transformation, it has become feasible to modify the pathway and flower color through genetic engineering. One of the advantages of molecular breeding is that flower color can be specifically modified without changing the other characteristics of the targeted variety. Novel flower color varieties such as brick...
