The enhancing effect of three marine bioactive substances (MBS) – EXT1116, NA9158 and 251104 – on the absorption of ammonium and potassium by the root system and the growth of potted grapevine (Vitis vinifera L.) plants is reported. Root ion influxes were determined in vivo by the non-invasive vibrating probe technique. Treatment with MBS generally enhanced nutrient absorption only in the root region between 0.8 and 1.7 mm from the root apex. Among the three substances tested, EXT1116 was the… CONTINUE READING
