high temperatures enhance GBSS activity on 14 days after anthesis in Yagmai 9, but then reduces GBSS activity significantly after 14 days after anthesis, greater diurnal temperature differences enhances GBSS activity under optimum temperatures, but reduces activity slightly under high temperatures | Triticum aestivum |
| 2.4.1.242 | additional information | - |
in Xuzhou 26, high temperature affects GBSS activity slightly on 14 days after anthesis, but reduces GBSS activity on both 21 and 28 days after anthesis, greater diurnal temperature differences enhances GBSS activity under optimum temperatures, but reduces activity slightly under high temperatures | Triticum aestivum |
