Abstract:Based on the investigation and analysis of the cadmium content in 8 kiwifruit varieties(Jinkui, Jinyan, Cuiyu, Donghong, Hongyang, Fengyue, Kuimi, Miliang No. 1) in partial adult kiwifruit orchards in Hunan Province, Miliang No.1 and Jinyan Kiwifruit with different cadmium enrichment capacity were selected to study the difference in cadmium absorption and transportation under cadmium stress(5, 10, 15, 20 mg/kg). The results showed that the cadmium content of the eight kiwifruit varieties in the adult orchard did not exceed the national standard value(0.05 mg/kg) when the soil was polluted by moderate cadmium(0.9 mg/kg). The cadmium content of kiwi fruit is the highest in ripening period. Under cadmium stress, the cadmium content in the organs of Miliang No. 1 and Jinyan increased with the increase of cadmium treatment concentration, and the enrichment ability was stronger when the cadmium concentration was lower. The cadmium distribution coefficient in the root is the largest(>0.90) and the fruit is the smallest. indicating kiwifruit mainly absorbs and accumulates cadmium from the root. The absorption and accumulation of cadmium in the whole plant of Miliang No. 1 were significantly higher than that in the whole plant of Jinyan, but the transfer ability of cadmium of Jinyan is stronger than that of Miliang No. 1 and the cadmium content of Jinyan fruit is significantly higher than that of Miliang No. 1.
