Etude comparative de quelques stimulateurs de la croissance végétale provenant des plantes spontanées

Abstract

This study investigated the effects of aqueous leaf extracts of Artemisia herba alba L. from the Asteraceae (Chih) family and Malva parviflora from the Malvaceae family (Khoubeïz)., on the growth and the germination rate in the SorghumVulgare plant of the Poaceae (Sorghum) family two spontaneous medicinal plants harvested in April 2021, in the Sebseb region of the wilaya of Ghardaïa,. The aqueous extract is obtained after extraction at reflux. The tests are carried out at different doses of the aqueous extract (0%, 50% and 100%), this study has shown that the 50% extract of Malva parviflora has high efficiency in growth and germination rate ( 60 ± 2.08%) The growth kinetics of SorghumVulgare (Sorghum) treated with different dilutions of the aqueous extract of Malva parviflora, show a significant increase in the growth kinetics over time, The aqueous extract of Malva parviflora promotes growth and germination rate in plants and can be used as a fertilizer.
