Dynamic Accumulation of [Beta]-carotene and Dry Matter in Orange-fleshed Sweetpotato [Ipomoea batatas (L.) Lam] and Their Correlation Analysis

Using three orange-fleshed sweetpotato varieties as experimental materials, 16 economic traits at 60 d, 75 d, 90 d, 105 d, 120 d and 135 d after planting were measured, so as to revealing the dynamic variations of β-carotene and dry matter accumulation in roots and their relationships with economic...

Summary:Using three orange-fleshed sweetpotato varieties as experimental materials, 16 economic traits at 60 d, 75 d, 90 d, 105 d, 120 d and 135 d after planting were measured, so as to revealing the dynamic variations of β-carotene and dry matter accumulation in roots and their relationships with economic traits in orangefleshed sweetpotato. The results showed that the dynamic variations of β-carotene accumulation in tubers varied hugely among different varieties. Interesting, the βcarotene content of all three varieties showed a significant decrease after 120 d, while the dry matter content of them performed a similar "fluctuation-type". Correlation analysis indicated that β-carotene content of three orange-fleshed sweetpotato varieties had no significant correlation with dry matter content and photosynthetic parameters, but the correlation with other economic traits also varied among varieties.
