HETEROGENEITY OF PROGENY IN MERISTEM CULTURE

J.Y. Kouadio, C.T. Phan
Plants obtained by meristem culture from the different nodes of a tomato mother plant (Lycopersicum, esculentum, L. cultivar "Jumbo") show a higher precocity of plants from the median nodes (4 and 5).

The distribution of phenolic compounds, proteins and nucleic acids decreases from the top to the bottom of the mother plant.

The total soluble sugars decrease also from the apex to the bottom when the plant is young, while, we notice a relative increase of the sugar concentration in the bottom nodes as the plant aged.

The plants from median nodes, the most precocious contains the lowest concentration of sugar while their concentration of phenolic compounds is the highest.

We then interest ourselves on the qualitative study of these compounds including enzymatic studies, and certain conditions which can sway the heterogeneity observed.
