Cannabis sativa L. is an ancient crop with medicinal and industrial applications that is cultivated to use its fibers and is also an effective painkiller. Cannabinoids are terpenophenolic compounds that have only been identified in cannabis genus. In the present study, the effect of cycocel on the amount of delta-9-tetrahydrocannabinol (THC), the main cannabinoid of cannabis plant, in both male and female cannabis plants was evaluated as a factorial experiment in a completely randomized design with three replications at greenhouse of Bahonar university of Kerman. The main factors included both genders of cannabis plant, male and female and different concentrations of cycocel (0, 500, 1000 and 1500 mg/l). THC was measured by liquid chromatography and UPLC, and total soluble proteins, total soluble sugars and malondialdehyde were analyzed using a spectrophotometer. The results were showed that with increasing cycocel concentration to 500 mg / l, the amount of tetrahydrocannabinol (THC) in the leaves and flowers of the female cannabis significantly increased. Comparing the interaction of genders and cycocel, it was found that the active ingredient of leaves in the female plants had a higher increase than the male plants up to a concentration of 1000 mg/l. The results also demonstrated that concentration of 1000 mg/l had the highest protein content in compare to other treatments in both male and female plants. The content in male gender was higher than the female base up to 1000 mg /l, but at the concentration of 1500 mg/l the female base was better. The lowest quantities of malondialdehyde and other aldehydes was observed in both genders treated with 1000 mg /l cycocel. Overall cycocel concentrations in compare to the control increased the soluble carbohydrates and reducing sugars. According to the obtained results, to achieve the maximum active ingredient of THC, application of 1000 mg/l cycocel in female gender is recommended.

Newspapers with poor seed germination is slow. Crust has been suggested to be due to poor germination. In the present study astrophysical seed scarification experiment in a completely randomized design using 98% sulfuric acid at time 0, 1, 2, 3 and 4 h in 4 replications was applied to the seed. Characteristics such as germination percentage, germination rate, root length, stem length, root fresh weight and fresh weight of stem were investigated. The variables measured in this study were the percentage and rate of germination, shoot length, root length and root fresh weight and root stipes, shoot length, root fresh weight, shoot to root ratio was calculated. Effect of scarification with sulfuric acid results showed that the germination percentage increased with increasing duration of treatment, So that the highest mean germination percentage (90%) and acidtreated 4 hours with an average minimum of distilled water (10%) achieved a statistically significant difference in the time indicated. Germination percentage of modifications on the ninth day of the experiment showed that the beginning of the experiment showed a rapid increase But after 15 days, germination was slow or stop the treatments. 3 and 4 h of acid treatment than the other treatments showed better germination percentage during the evaluation period, Control treatment had the lowest rate of germination. Sulfuric acid results in this study have a positive effect on seed germination was followed with Canna.
