芥藍耐熱品種選育

本研究在高溫環境下評估芥藍品種之耐熱性，並利用葉綠素計讀值、葉綠素螢光及電解質滲漏率評估作為耐熱性生理指標之應用性，以期選育出耐熱、品質佳、豐產之芥藍新品種。在生長箱日夜溫度35℃／30℃之處理下，32個芥藍品系中，初步篩選出編號16-1219及16-1223之soil and plant analyzer development（SPAD）值在30以上、電解質滲漏率在50%以下及萎凋指數在65%以下，屬於較耐熱的品系。 This research is to evaluate heat tolerance in Chinese kale for the purpose of new variety selection. The physiological indices under high temperature conditions, such as soil and plant analyzer development (SPAD), maximal quantum efficiency of PSII (Fv/Fm) and electrical conductivity (EC) value, were investigated for heat tolerance selection in addition to high quality and high yield. In the growth chamber of day/night temperature 35℃/30℃, thirty-two Chinese kale lines were screened.
