Response two genotype of bean to spraying salicylic acid and boronic acid
Abstract
The effects of spray nutrition with boron and salicylic acid on two genotypes of bean plants, Local and Spanish genotypes, learned using a Randomize complete block design (RCBD) in growth season 2023-2022. Three boron concentrations (0, 25, 50) mg. L1 and salicylic acid concentrations (0, 100, 200) mg. L-1 were used, each coefficient contains three replicates. Plant height, glucose content, protein content, and biological yield were all studied. The results explain that 100 mg. L-1 of salicylic acid concentrations gives maximum values for plant height and biological yield. The concentration of 200 mg. L-1 of salicylic acid gives maximum values in protein and carbohydrate content. The concentration 50 mg. L-1 of boon produced the greatest plant height and carbohydrate content, while the concentration 25 mg. L-1 of boron yielded the greatest protein content. The biological yield decreased significantly. The local genotype excelled in carbohydrate content, while the Spanish genotype excelled in plant height, protein content, and biological yield. The interaction between types and boron concentration revealed that the Spanish genotype had the maximum plant height and protein content at 25 mg. L-1, However local genotype gives the maximum value of carbohydrate content at 50 mg. L-1, while the biological yield did not achieve any significant increase. The interaction between salicylic acid and genotypes produced the greatest plant height and biological yield for the Spanish genotype, whereas the concentration of 200 mg. L-1 of salicylic acid produced the greatest of protein content for the local genotype. The local species had the maximum carbohydrate content at the concentration 100 mg. L-1 of salicylic acid. When both salicylic acid and boron concentrations were applied at 100 and 0 mg. L-1, the result explane the interaction between them achieved a significant increase in plant height and biological yield, whereas the interaction of 100 mg. L-1 of salicylic and 25 mg. L-1 of boron concentrations gives significant increase in protein content. Furthermore, combining concentration 200 mg. L-1 salicylic acid with 50 mg. L-1 boron an in achieved a significant increase in carbohydrate content. As a result of the three-way interaction between three research components, a concentration 200 mg. L-1 0f salicylic acid with 25 mg. L-1 of boron yielded the maximum value for plant height of the Spanish genotype. while, the Spanish species had the maximum protein content at a concentration 100 mg. L-1 of salicylic acid with 25 mg. L-1 of boron. The concentration is 200 mg. L-1 of salicylic acid with 50 mg. L-1of boron, on the other hand, provided the greatest value for carbohydrate content of the local genotype.
