Sesame (Sesamum indicum L.) belongs to the family (Pedaliaceae), and the crop is valuable. Sesame is an oilseed plant, and the study of its storage conditions is essential. Cryoprotectants are usually lower the freezing point of the solution and is blocked the creation of ice crystals in inside and outside solution of the cell. In this research was performed, cryopreservation to method vitrification with two types of solution protecting PVS2 and PVS3 in 7 times (20, 40, 60, 80, 100, 120 and 140 minutes). This experiment factorial was studied in the form of with completely randomized design (CRD) with two factors protective solution (two level) and time levels (seven level) and three replications. The results of analysis of variance for treatment time and soluble type in three traits, percentage germination, root and shoot length was significant at the level of 1% (P

Background and purpose: Basil is annual herb it belongs to the mint family and it has 30 species; therefore, in this research, optimization of tissue culture conditions of purple basil plant for callus production, identification of callus induction percentage, growth rate, growth speed and relative water content of callus was done through tissue culture. Materials and Methods: The callus induction optimization experiment was carried out as a factorial in the form of a completely randomized design with 4 factors, micro samples and three levels of BA, IAA and IBA hormones. Findings: The results showed that the highest percentage of callus induction (88%) was related to the culture medium containing 2 mg/L IBA and 2 mg/L BA. The effect of hormonal compounds on the four investigated characteristics of callus generation percentage, growth speed, relative water content and growth rate (dry weight) has had a significant effect, which can be used to select the best combination in callus formation and tissue culture optimization, and finally the future goals of the breed. Also, the interaction effect of two explant factors and hormonal compounds only had a very significant effect (P≤1%) on the growth rate index. Conclusion: The quality of the induced calluses indicates the correct selection of explants and suitable hormonal compounds. Therefore, there is a direct relationship between callus production and growth regulators, and also according to the type of plant studied and the amount of hormone present in it, the amount of growth regulators used in callus induction will be different.

In this research was performed, cryopreservation to method vitrification with two types of solution protecting PVS2 and PVS3 in 7 times (20, 40, 60, 80, 100, 120 and 140 minutes). This experiment factorial was studied in the form of with completely randomized design (CRD) with two factors protective solution (two level) and time levels (seven level) and three replications. The results of analysis of variance for treatment time and soluble type in three traits, percentage germination, root and shoot length was significant at the level of 1% (P<0.01). Interaction between the time treatment in solution type for the length of root and shoot length were significant at the level of 1% (P<0.01) for germination percentage was insignificant at the level of 5% (P<0.05). Overall, analysis of variance showed that is effective the protective solution type and levels of treatment time in the process of vitrification and the cryopreservation Sesame plant in assessment indicators.
