Did the addition of rooting compound make any difference in the time it took to develop roots? Did it make any difference in the
harkovskaia [24]

Answer:

In in vitro plant tissue culture, indolbutyric acid and other auxins are used to initiate root formation in a procedure called micropropagation. The micropropagation of plants is an asexual propagation or propagation technique that is based on the organogenetic potential of plant cells, which consists of cultivating in vitro on appropriate substrates, isolated cells, portions of yolk meristems, vegetative apices at the beginning of their development or microstaquillas. Small samples of plants used are called explants. Auxins such as indolbutyric acid can be used to cause mass formation of undifferentiated cells called corns. Callus formation is often used as a first step in the micropropagation process since, by exposure to certain auxin hormones, callus cells can be induced to form other tissues such as roots.

Indolbutyric acid is often used to promote the rooting of stakes. In a study in Camellia sinensis, the effect of three different auxins, indolbutyric acid, indolacetic acid and 1-naphthalenacetic acid on root formation was measured. According to the authors, indolbutyric acid produced a higher root yield compared to other auxins.9 This effect of indolbutyric acid is consistent with that found in other studies; This hormone is considered the most commonly used auxin for root formation, 10 because it is much more potent than indolacetic acid and other synthetic auxins.7

Jatropha curcas is a species in which there is an improvement in the quality of the rooting of the stakes with the addition of indolbutyric acid in the middle (longer root length, number of roots, percentage of rooted stakes, and dry root weight) , 11 although not always the effect on rooting is statistically significant.

1 Both types of succession require the same amount of time to occur.

2 Both types of succession result in greater biodiversity over time.

3 Both types of succession decrease the stability of an ecosystem.

4 Both types of succession have the same starting conditions.

5 Both types of succession eventually lead to a community closer to equilibrium.
