The warming climate changes the agrobiological properties and nutritional conditions of perennials, affecting the quality of the plants. Perennial Allium species plants are considered of a high nutritional value. Using sustainable cultivation technologies, they can grow in one place for up to six years. Therefore, it is very important to preserve and select plants suitable for the conditions of the changing climate. Investigations were carried out in the crop rotation experimental field station at the Lithuanian Research Centre for Agriculture and Forestry of the Institute of Horticulture during 2017n2021. The experiments were carried out on plants of Allium schoenoprasum L., Allium angulosum L., Allium nutans L. and Allium fistulosum L. in the spring of 2017. Plants were propagated vegetatively - by dividing the three-year-old sprouts into six-eight bushes and planted on a flat surface. The complex effect of abiotic and biotic factors on the vegetative and generative development of perennial Allium plants was investigated in the collection. The selection of valuable individuals was carried out, long-term observations and development of plant growth stages were performed, adaptation to soil and climatic conditions and plant productivity were assessed.
