Plant chromosome manipulation is a powerful tool in plant breeding due to its significant impact on various genetic traits and diversity. To investigate the effect of polyploidy induction in anise (Pimpinella anisum L.), three different concentrations (0.01%, 0.5%, and 5%) of colchicine were tested. In this study, the seeds and terminal buds of five-week-old plants were treated with colchicine, and the process was repeated for three consecutive days. Subsequently, molecular, physiological, and morphological traits of both control (diploid) and induced (autotetraploid) plants were investigated. The results revealed that 0.01% colchicine had no significant effect on ploidy induction, while significant effects were observed at 0.5% and 5%.  Seedlings treated with concentrations higher than 0.5% colchicine exhibited larger stomatal size, lower stomatal density, and darker leaf color. In addition, the contents of DNA, RNA, and total protein increased in seedlings treated with concentrations of 0.5% and 5%. Karyotype observation confirmed polyploidy induction in plants treated with colchicine concentrations above 0.5%.  Overall, this study shows that  colchicine  can alter anise plants’ ploidy by 0.5% and 5% and  boostleaf size and pigments associated with photosynthesis, resulting in stronger plants.

The industrial maintenance of livestock and poultry on a large scale in an intensive manner has increased the possibility of diseases, which reduces the occurrence of these diseases helps to increase growth and improves production traits. Today, the use of growth-promoting antibiotics has been limited due to the possibility of bacterial resistance and also transmission through manufactured products to consumers. Medicinal plants with antimicrobial effects and reduced serum lipids have been proposed as suitable alternatives for antibiotics. The origin of many medicines are herbal plants because due to the lipophilic nature of the effective oils found in some medicinal plants, these compounds can completely disrupt the membrane structure of bacteria, especially Gram-negative bacteria, and even some effective oils in essential oils have Irritation of the digestive system, increasing the production of digestive enzymes, improving the use of digestive products and the body's immune response. The most important biological activity of medicinal plants is related to antioxidant and antibacterial activities, related to their biologically active molecules such as carvacrol, thymol, cineol, allicin, capsaicin, piperine, etc. The property of stopping the reproduction of the disease agent or the lethality of the disease agent is a common point between chemical drugs and medicinal plants, but creating a protective layer on the intestine to prevent the penetration and growth of the coccidiosis agent in the intestines and stimulating the body's immune system against the disease agent is a unique feature.
