Abstract:
Plant tissue culture is an important biotechnological technique for the production, conservation and regeneration of in vitro culture of higher plants. Biostimulants are biological, organic and synthetic components that promote plant growth and some seaweeds have been used as adequate additive for improving tissue culture as an efficient method for plant mass propagation. Modern microscopy techniques employ the management of image processing software for the extraction of numerical data from the images for better analysis. This work analyzed the biostimulant effect of marine seaweeds: Sargassum cymosum and Ulva fasciata and powders on the morphometric characteristics of Sedum praealtum explants by the image analysis of their shape descriptors and distance dispersion measurement validating the application of non-destructive digital morphometrics that allows describe the shape plasticity’s of S. praealtum explants under seaweed biostimulation. This study reveals that instead of inducing a simple linear acceleration of growth; both seaweed powders function as a highly sensitive, concentration-dependent morphogenetic switch that actives the structural development and biomass quality in succulent micropropagation and mass-regeneration systems.
