TRAVIESO, María del C et al. In Vitro evaluation of phospholipids effect on germination of tomato seeds (Lycopersicon esculentum Mill). cultrop [online]. 2015, vol.36, n.2, pp. 148-152. ISSN 1819-4087.

The effect of a mixture of natural phospholipids applied as substrate on filter paper on in vitro germination of tomato seeds of three varieties (Amalia, Campbell 28 and Vita) was evaluated. In all cases, an inducing effect on the radicular growth of seedlings derived from newly germinated seeds, given by lengths of radicles significantly higher in treated groups compared to controls were showed. Althought hypocotyles maxims longitudes were higher in this group with respect to control, no statistical difference in this growth indicator were evidenced. There was not homogeneous behavior in terms of percentages of germination. These results demonstrate the potential use of these compounds as inducers of radicles growth plant and are the first obtained in Cuba on the exogenous application of phospholipids as roots bio-stimulants, opening a new way to study the biological roles of these biomolecules and its exogenous application in economic and social impact crops
