Studies on the efficacy of extracts of Reynoutria sachalinensis on cucumber growth using the richards function and evolutionary modelling

The effect of R. sachalinensis extracts against powdery mildew of cucumbers in relation to the growth of leaf blade and petiole of leaves cucumber (No. 1-6) was studied in small-scale experiments, during the growth period using the Richards function. In this paper, the Richards function in the logarithmic form was used to precisely analyze growth of leaf blade and petiole of the leaves. The equations for each individual organ were fitted using Evolutionary Algorithms. Also, the improvement of unknown parameters´ values was defined through Evolutionary Algorithms. So, by estimating the (near) optimal model of the growth of each individual organ, the proposed method manages to simulate the growth of the plant and how Reynoutria sachalinensis extracts against powdery mildew of cucumbers affects it, as demonstrated by experimental results.
