Effect of nutrient regime on patterns of resource allocation in Phaseolus vulgaris L. (kidney bean).

Common bean is an important component of the production systems and a major source of protein. Nutrient solution concentration is a critical factor affecting plant growth in soil. Here, we investigated the effects of Nutrient solution on the growth and Phaseolus vulgaris L. (kidney bean) plants. First, were cultivated soil in two different nutrient with low, high concentrations and distilled water as control (0.0; 1.375, 22mM). Shoot and root length yield increased at (final week) days after plantation (DAP) of shoot and decreases of root length of bean, we examined the effect of nutrient changes of the cultivation period on the growth using high and low nutrient conditions. In plants transferred from high to low,the number of attached leaves increased toward the end of the first week of the cultivation period. Whereas this value increased in leaf length on concentration of high nutrient 22mM and decreases in concentration of lower 1.375mM of nutrient regime. The density of hairs showed on adaxal and abaxal leaf surface not significant difference between them. Our results suggest that the regulation of nutrient regime during the cultivation period affects the growth characteristics of bean. The effect of nutrient on fresh and dry weight of shoot was affect by high dilution 22mM shoot fresh weight, while the fresh weight root not affect by concentration on bean. [ABSTRACT FROM AUTHOR]
