uses and effects of auxins

Top PDA Devices thumbnail
-like characteristics. Auxins have a cardinal role in coordination of many growth and behavioral processes in the plant's life cycle and are essential for plant body development.

. The most important auxin produced by plants is indole-3-acetic acid ( IAA ). Link to illustrated description of seed development.] is initiated by the accumulation of auxin. Already-developing leaves deplete the surrounding cells of auxin so that the new leaves do not form too close to them. In this way, the characteristic pattern of leaves in the plant is established. . Plant shoots display positive phototropism : when illuminated from one direction, the shoot proceeds to grow in that direction.

    • Dr. A.K. Kepcka Fruit-setting and the development of fruits, as influenced by application of auxins, or by artificial pollination, has been observed in many experiments carried out for several years in the Department of Vegetable Crops of the Warsaw College of Agriculture, in Skierniewice, in order to establish the best method of improving the setting and increasing the yield of good quality glasshouse tomatoes. Since the effects of auxin sprays and artificial pollination on fruit-setting and the early and total yield of tomatoes are known very well, it seems sufficient to present our data on these phenomena in outline only, so that the main purpose of this paper could be a discussion in more detail of the influence of these treatments, as well as the influence of the environmental conditions, on fruit quality .
