- Title
EFFECTS OF POWDERED ROOTING HORMONE ON THE GROWTH OF DIEFFENBACHIA.

- Abstract
Gardeners and farmers use rooting hormone on plants to speed up the process of propagation and increase the likelihood of healthy plants, in December of 2006, 20 Dieffenbachia cuttings were planted in pH-balanced soil. Prior to planting, 10 of these cuttings were dipped into powdered rooting hormone containing auxin. All 20 plants were watered with distilled water until water seeped through the hole in the bottom of the pot. All plants were grown in a greenhouse under artificial light at a temperature between 20°C and 23°C. They were given a month to grow. The average root length of the plants without hormone was 15 mm. longer than those with hormone. The average number of roots for a plant with hormone was 6 more than plants without the hormone. Additional observation showed that the plants without hormone had stronger stalks and greener leaves. These additional observations along with the measured results lead to the conclusion that the plants without hormone were healthier.
