2，4 D、Dicamba和KT对小麦成熟胚离体培养的影响Abstract:The aim of this study was to investigate the effects of the herbicides 2,4 D, Dicamba, and KT on the in vitro culture of mature embryos of wheat. Results showed that the herbicides had a significant effect on the growth and developmental characteristics of the embryos. 2,4 D and Dicamba showed a strong inhibitory effect, while KT showed a promoting effect on the embryo growth. The study highlights the potential for the use of KT to enhance the in vitro culture of wheat embryos and proposes further research to explore the molecular mechanisms underlying the effect of herbicides on plant development.Introduction:Embryo culture is an essential technique for the propagation and multiplication of wheat plants. It involves the growth of immature embryos, in a sterile medium, under controlled conditions. The use of plant growth regulators, such as hormones, is a common technique to enhance the in vitro culture of embryos. However, herbicides, which are often used in agriculture to eliminate weeds, could also affect the growth and development of plants. The aim of this study was to assess the effects of commonly used herbicides 2,4 D, Dicamba, and KT on the in vitro culture of mature embryos of wheat.Methods:Mature embryos of wheat were used for the study. The embryos were extracted from the spikes and sterilized to avoid contamination. The embryos were then cultured in a Murashige-Skoog (MS) medium supplemented with different concentrations of 2,4 D, Dicamba, and KT. The experiment was conducted for a period of four weeks, after which the samples were analyzed for growth and developmental characteristics.Results:The results of the study showed that the herbicides had a significant effect on the growth and development of the embryos. Addition of 2,4 D and Dicamba showed a strong inhibitory effect on the growth of the embryos, while KT promoted embryo growth. The highest growth rates were observed in samples treated with 3 mg/L of KT. The embryos treated with 2,4 D and Dicamba showed a substantial reduction in shoot and root growth.Discussion:The results of the study indicate that the use of herbicides could have significant consequences on the culture of wheat embryos. The growth and developmental characteristics were found to be strongly influenced by the three herbicides studied. The study also highlighted the potential use of KT to enhance the in vitro culture of wheat embryos. The observed promotion of embryo growth by KT is similar to its role in stimulating plant growth and development.Conclusion:The results of the study suggest that the use of herbicides, such as 2,4 D and Dicamba, should be applied with caution, as they have been shown to inhibit the growth and development of wheat embryos. In contrast, the use of KT may enhance the in vitro culture of wheat embryos. This study sheds light on the potential impact of herbicides on plant development and paves the way for further research to investigate the molecular mechanisms underlying the effect of herbicides on plants.The use of herbicides in agriculture is essential for crop production and weed control. However, their potential impact on plant growth and development cannot be ignored. The results of this study highlight the need for caution when using herbicides, as they may have unintended consequences on plant development. In particular, the study showed that 2,4 D and Dicamba had a strong inhibitory effect on the growth and development of wheat embryos, which could have a significant impact on crop yields.On the other hand, the study also revealed the potential for the use of KT to enhance the in vitro culture of wheat embryos. This is consistent with previous studies that have shown that KT can promote plant growth and development, and suggests that it may have potential applications in agriculture. Future research could investigate the optimal concentration of KT for enhancing wheat embryo culture, as well as explore the molecular mechanisms underlying its effect on plant growth and development.Overall, this study contributes to our understanding of the potential impact of herbicides on plant development and highlights the need for further research to investigate their effects. It is important to balance the benefits and risks of using herbicides in agriculture, and to explore alternative approaches to weed control that minimize their impact on plant growth and development. By doing so, we can ensure sustainable crop production while minimizing negative effects on the environment and human health.The findings of this study have important implications for farmers, policymakers, and the agriculture industry as a whole. Herbicides are widely used in modern agriculture to control weeds and increase crop yields. However, as this study shows, they may have unintended consequences on plant growth and development that could ultimately impact crop yields and food secu
