9. Physiological Analysis of the Growth and Productivity of Radish Varieties

Author: Walid al Humrani


Laboratory experiments were conducted with young plants of three radish varieties. An analysis of the growth and distribution of the biomass by authorities 15 days after the beginning of root formation. Certain parameters of the photosynthetic apparatus were determined – total leaf area surface and leaf blade and cotyledon. For the same period the biological and economic productivity of the photosynthetic apparatus in different varieties was recorded.
It was found that the relative growth rate (RGR) of the different experimental varieties varied, being highest in Edri cherveni (Big red). The biggest photosynthetic apparatus was observed in the same variety. Economic productivity is the highest in the Sachs variety.
