Ascophyllum nodosum extracts (ANE) are well-established plant biostimulants that improve stress tolerance and crop vigour, while also having been shown to stimulate soil microbes. The intersection of these two stimulatory activities, and how they combine to enhance plant health, however, remains poorly understood. In the present study, we aimed to...

There is an increasing global concern about the availability of water for agricultural use. Drought stress negatively impacts plant physiology and crop productivity. Soybean (Glycine max) is one of the important oilseed crops, and its productivity is often reduced by drought. In this study, a commercial extract of Ascophyllum nodosum (ANE) was eval...

Previous experiments have demonstrated positive effect of Acadian® extract of Ascophyllum nodosum on plant stress-resistance, however the mode of action is not fully understood. The aim of this study was to understand the physiological effect of Acadian® seaweed extract on the plant response to drought stress. Leaf temperature and leaf angle were m...

Bibb-type lettuce is one of the leading greenhouse vegetables grown in North America and the world. Almost all greenhouse lettuce is produced hydroponically using computerized production systems such as ebb and flow, NFT, and floating raft systems. Greenhouse production of lettuce is relatively small compared to field grown. But because it is clean...

Many vegetable and ornamental bedding plant crops are grown in plug trays and cell packs under greenhouse conditions prior to transplanting into the field or landscape. The development of a large, healthy root system is important for young seedlings to help withstand the shock of transplanting. Seaweed extracts are known to improve root development...
