Foliar application of glycinebetaine—a novel product from sugar beet—as an approach to increase tomato yield

Gas exchange and chlorophyll synthesis of maize cultivars are enhanced by exogenously-applied glycinebetaine under drought conditions

“…Exogenously applied GB can rapidly penetrate through leaf surface and be easily transported to other plant organs, where it would contribute to improvement in stress tolerance (Mäkelä et al 1998). Response to drought stress differs noticeably among different crop cultivars due to their inherent differences in droughttolerance (Huang and Zhao 2001).…”

“…GB might contribute to restrict cytoplasmic dehydration and maintain leaf turgor in plants subjected to water deficit conditions (Iqbal et al 2008), thereby maintaining high photosynthetic activities. Thus, increased photosynthetic capacity could then lead to improved capability of the plant to allocate more assimilates to developing seeds (Mäkelä et al 1998).…”

Plant ALDH10 Family

“…vars synthesize considerably lower levels of GB, and naturally occurring GB-deficient inbred lines have also been identified (44). Moreover, certain maize varieties with tomato and pea do not accumulate GB due to the loss of a functional CMO (choline monooxygenase) gene (45)(46)(47), correlated with the very low activity of ZmAMADH1b, ZmAMADH2, SlAMADH2, and PsAMADHs with BAL (below 1.5% compared with that with APAL; Fig. 3) (4).…”

The influence of NANO-GRO® organic stimulator on the yielding and fruit quality of field tomato (Lycopersicon esculentum Mill.)

“…Therefore, it is relevant to support plants by the application of stimulators. In recent years, numerous studies have been carried out both on vegetables and fruit plants, as well as ornamental ones, where different kinds of preparations belonging to stimulators were examined (Mäkelä et al 1998, Ashraf and Foolad 2007, Basak 2008, Skórska 2011, Gorczyca and Kasprowicz 2011, Matysiak et al 2011, Nardi et al 2016). Each of them had a specific composition.…”

“…This process must be changed so that the plant can become more resistant to stress. At the moment there are a lot of preparations on the horticulture market which support plants, and research on new ones is in progress (Mäkelä et al 1998, Matysiak and Adamczewski 2009, Kocira et al 2013, Mila and Dobromilska 2013. NANO-GRO ® is a stimulator with a unique composition, which has the form of an oligosaccharide granule (sucrose purified of 98% ethyl alcohol) soaked with sulfate elements: Fe, Co, Al, Mn, Mg, Ni, Ag at nanomolar concentrations.…”
