Example, to search for all recorded cases of biostimulant use on tomato mitigate effects of drought type: "tomato, drought"


Type: Seaweed extract, Company: BioAtlantis


No effect on drought stress tolerance
No effect on produce quality

BioAtlantis treated Hydrangea, cv. Phantom, grown in a peat-based substrate in drought stress conditions had 2 % longer branches, 14 % less branches, 3 % less fresh weight, 2 % more dry weight, a 2 % better root development, a 9.5 %higher chlorophyll-index, a 22.8 % lower flavonol-index, a 44.1 % lower anthocyanin-index and a 10.7 % higher stomatal conductance  compared to the untreated control grown in the same conditions. No significant effects.
