Mendel's presentations were published as "Experiments on Plant Hybridization" in the Proceedings of the Nature Research Society of Brünn in 1866.

Mendel published the results of his experiments in the year 1866.

Gregor Mendel
Gregor Mendel was an Austrian scientist and Augustinian friar who is known as the "father of modern genetics". He conducted groundbreaking experiments on pea plants in the mid-19th century, which laid the foundation for the understanding of inheritance and the laws of genetics.

Mendel's Experiments
Mendel conducted his experiments between 1856 and 1863 at the St. Thomas's Abbey in Brno, Austria-Hungary (now in the Czech Republic). He carefully designed and controlled his experiments using pea plants, which allowed him to study the patterns of inheritance in a systematic manner.

Publication of Results
After conducting his experiments, Mendel presented his findings to the Natural Science Society in Brno in 1865. However, it was not until the following year, in 1866, that he published his results in the society's journal, "Verhandlungen des naturforschenden Vereines in Brünn" (Proceedings of the Natural History Society of Brünn).

"Experiments on Plant Hybridization"
Mendel's publication, titled "Experiments on Plant Hybridization," outlined his experiments, observations, and conclusions. In this paper, he described the fundamental principles of heredity, which would later be known as Mendel's Laws of Inheritance.

Reception and Impact
Initially, Mendel's work went largely unnoticed and was not widely recognized. It was only in the early 20th century, several decades after his death, that his experiments were rediscovered and his contributions to genetics were fully appreciated. His work formed the basis for the field of genetics and revolutionized our understanding of how traits are passed from one generation to the next.

Conclusion
In conclusion, Mendel published the results of his experiments on plant hybridization in the year 1866. His groundbreaking work laid the foundation for the field of genetics and is still widely studied and celebrated today.
