Study of the Effect of Pretreatment of Corms by Different Concentrations of Gibberellic Acid and at Different Periods on the Growth, Flowering, and Quality of Saffron in Eastern Morocco

Table 6

Effect of different GA₃ concentrations and duration of application on the total weight of corms, the percentage of large-diameter wire corms, the coefficient of corm propagation and the ratio of harvested flowers to total corm weight. Values with the same letter in each application period in the column are not significantly different (); ns: not significant; significant at 5%; significant at 1%, significant at 1%.

Duration of application	Treatment GA3	Total weight of corms (g)	Large wire corms (%) CCF	The ratio of the weight of bulbs produced and bulbs planted (%) (CPC)	The ratio between the harvested flowers and the total weight of corms (RFRPC)
