烤烟硫营养对钙吸收与积累的影响
Effect of sulfur nutrition on accumulation and uptake of calcium in lfue-cured tobacco
摘要
Abstract
A hydroponics experiment was carried out to investigate calcium content, accumulation and uptake in root, stem and leaf in flue-cured tobacco under different sulfur concentrations. Results showed that calcium contents in root, stem and leaf were reduced significantly or highly significantly along with increase of sulfur concentration from 0 mmol/L to 8 mmol/L. The uptake rate and accumulation of calcium in root, stem and leaf were reduced along with increase of sulfur concentration from 2 mmol/L to 8 mmol/L. Calcium uptake rate in root under 0 mmol/L sulfur concentration was lower than that under 2 mmol/L. Calcium uptake rate in leaf under 0 mmol/L sulfur concentration was higher than that under 2 mmol/L from rosette to fast growing stage, while calcium uptake rate in stem nder 0 mmol/L sulfur concentration was higher than that under 2 mmol/L from fast growing to maturation stage. Calcium accumulation in root under 0 mmol/L sulfur concentration was lower than that under 2 mmol/L, but no significant difference under 0 mmol/L and 2 mmol/L sulfur concentration in stem and leaf. No or lower sulfur concentration promoted calcium uptake and accumulation in root, stem and leaf.关键词
