Abstract

The fresh consumption of mulberry fruit and the use of its leaves in sericulture are two aspects of the most important applications of this multi-purpose tree. The developing sericulture industry and not depending on the import of silk to the country, and most importantly, the creation and expansion of this industry for the sustainable development of rural areas has made the supply of leaves needed for feeding silkworms to be a priority for the sericulture industry. Fast and cheap reproduction of high-yielding leafy cultivars is one of the concerns of this industry. In order to evaluate high-yielding leafy cultivars by vegetative propagation methods with cuttings, an experiment with seven cultivars with the effect of two hormones including indole butyric acid and naphthalene acetic acid at the rate of 20 mg/liter in three times of 12, 24 and 48 hours against the control in the form of a completely Randomization was done in a factorial manner. The results showed that based on the examined traits, the difference between cultivars was insignificant in terms of the type of treatment, but in terms of the duration of the effects of the treatments, there was a significant difference at the level of 1%. Regarding the rate of rooting and establishment of the cuttings, the difference between cultivars was significant, and the cultivar Kenmochi had the highest percentage (93.3) of rooting in both treatments. The cultivar Shin Ichinose was the least (45%) susceptible to rooting materials. Tachibana, kaeiryonezumi Gaeishi and Yukishinogi cultivars responded better to indole butyric acid (94, 74, 77%), while naphthalene acetic acid led to upper rooting percentage in Kenmochi and Kokuso cultivars (94, 80%).
