“…One can recommend that passage time of three months was the most suitable regarding the measured parameters and healthiness of cultures. Most researchers who worked on the micropropagation of Blackberry stated that period of 4 or 6 weeks as a passage time among subcultures (Fira et al, 2014, Gomes et al, 2017and Aly et al, 2022.…”

T HIS work aimed to establish an in vitro protocol for Blackberry "Karaka Black" micropropagation. Stem node explants were experimented on three types of medium salts (WPM, MS and B5) in establishment stage. Also, three types of cytokinins were tested for multiplication i.e. BA (0.0, 0.4, 0.8 and 1.2 ppm), TDZ (0.0, 0.1, 0.5 and 1.0 ppm) and Kin (0.0, 1.0, 5.0 and 10.0 ppm). Two soil mixtures were used in acclimatization stage. Finally, the effect of passage time and number of subcultures on multiplication rate were investigated. The results indicated that WPM followed by MS medium gave the highest shoot length and leaf number. BA at 0.4 ppm, Kin at 5.0 ppm and TDZ at 0.1 ppm achieved the most preferable values for multiplication stage but the kinetin one gave the healthiest plantlets. The most microshoots got well-formed roots in multiplication phase. Consequently, rooting stage was not required. The multiplication rate slightly decreased after the 3 rd subculture and three months of culture date proved to be the most suitable passage time among subcultures. Peatmoss and sand mixture gave the highest plantlet quality during acclimatization.

“…Gomes et al, 2017, carried out five successive subcultures on four genotypes of Blackberry, the multiplication rate of each genotype showed a fluctuation among the different subcultures. Consequently, 'karaka Black' may have its own behavior.…”

“…After 30 days of acclimatization in a greenhouse, rooted plantlets showed no significant losses. Blackberry cultivars can be conserved in vitro for 15 months, without subcultures and, after this time, they can be micropropagated on a large-scale, maintaining the regenerative potential and multiplication [11].…”

As a result of studies, it was found that collection samples of berry crops in vitro can be maintained in viable condition on specially selected nutrient media for 12 months. The effect of mannitol concentration (0.45, 0.75 and 1.05%; sucrose control -3%) on the regenerative potential of microprobe of the studied berry crop varieties was estimated. When studying the effect of the reproduction cycle on the morphogenesis of meristemic cultures, it was found that the dynamics of changes in shoot length, number of leaves and shoots depended on the concentration of the active substance. In general, the majority of berry crops that were viable after storage of explants retained the ability to grow again, in many cases reaching or exceeding the control level.
