The Effect of Boron Spraying on Some Productive and  Specificcharacter of two Ecotypes of Anise (Municipal and Shami) (Pimpinella anisum L.)

The lack of studies on the anise plant contributed to increasing the importance of the research, as the research was carried out in the Salhab region, Hama Governorate, Syria, for the agricultural season 2022-2023. The aim was to study the effect of boron spraying on some characteristics of two ecotypes of anise, which are the municipal anise and the Shami anise. Four concentrations of boron (0-25-50-75) mg/L had been studied according to the'' split plot design for one time only'' design. Thus, boron was sprayed twice at the beginning of flowering and at the beginning of the fruiting stage. In addition, averages were recorded, and significant differences were calculated. The results showed that the municipal ecotype was superior to the Shami ecotype in productivity per hectare, as model ecotype affected productivity.

The results of the interaction of the studied ecotypes with the studied concentrations of boron showed that there were significant differences between the studied treatments and control, while the interaction of the municipal ecotype of anise with boron 25 mg / L achieved a significant superiority over the rest of the treatments and control in terms of fruit weight / plant, and achieved the highest value of (18.62). g compared to control, which achieved the lowest value (7.46) g for the municipal ecotype.

On the other hand, the results of the interaction between the studied ecotypes and concentrations of boron (0,25,50,75) mg/l for the weight of 1000 fruits showed that there were significant differences between treatments and control. The interaction of the municipal aniseed ecotype with boron at a concentration of 75 mg / L achieved a significant superiority over the rest of the treatments and control. The interaction of the Shami ecotype with boron at a concentration of 75 mg / L achieved a significant superiority over the studied treatments and control in terms of the number of fruits /inflorescences.

The interaction of the municipal ecotype with boron of a concentration of 25 mg/L achieved the highest percentage of essential oil, which was (5.60%), while the lowest value was in the Shami ecotype and at the same concentration of boron, which was (2.40%). It was observed that there were no significant differences between the studied boron concentrations and the average concentrations in each of the rows, the weight of 1000 fruits, and the percentage of essential oil.

  In addition, there were no significant differences in the ecotype of the studied cultivars and each of the characteristics of the number of fruits in one flower, the weight of 1000 fruits, and the weight of the fruits/plant.
