Title (EN) PLANT GROWTH PROMOTER WITH STRIGOLACTONES REGULATION ACTIVITIES
(FR) PROMOTEUR DE CROISSANCE VÉGÉTALE AYANT DES ACTIVITÉS DE RÉGULATION DES STRIGOLACTONES
Abstract:
(EN) The present invention uses compound 3-OH-β-apo-13-carotenone (zaxinone) as a negative regulator of the plant hormone strigolactones (SLs). The compound 3-OH-β-apo-13- carotenone is a positive growth regulator which triggers the formation of crown roots and promotes growth in size and number of roots and shoots. Disclosed herein is a method of using 3-OH-β-apo-13-carotenone as a growth-promoting compound for cereal, grain and vegetable crops. The 3-OH-β-apo-13-carotenone compounds is also a negative regulator of strigolactone biosynthesis and release. Disclosed herein is a method of combating root parasitic weeds affecting cereal, grain and vegetable crops. Application of 3-OH-β-apo-13-carotenone to plant growth media down-regulates strigolactone production in cereal, grain and vegetable crops preventing root parasitic weed infestation of the crops by inhibiting germination of parasitic weed seeds.
(FR) La présente invention utilise le composé 3-OH-β-apo-13-caroténone (zaxinone) à titre de régulateur négatif des strigolactones (SL) d'hormones végétales. Le composé 3-OH-β-apo-13-caroténone est un régulateur de croissance positive qui déclenche la formation de racines en couronne et favorise la croissance en taille et en nombre des racines et des pousses. L'invention concerne un procédé d'utilisation de la 3-OH-β-apo-13-caroténone à titre de composé favorisant la croissance des cultures céréalières et légumières. Les composés de 3-OH-β-apo-13-caroténone sont également des régulateurs négatifs de biosynthèse et de libération des strigolactones. L'invention concerne un procédé de lutte contre les mauvaises herbes parasites des racines qui affectent les cultures céréalières et légumières. L'application de la 3-OH-β-apo-13-caroténone à des milieux de croissance végétale sous-régule la production des strigolactones dans les cultures céréalières et légumières, empêchant ainsi l'infestation par les mauvaises herbes parasites des racines des cultures par inhibition de la germination des graines desdites mauvaises herbes parasites.
