Shinn.] is an important cut flower for export trade in Taiwan. Market demand has been increasing with increasing planting area and production. However, nutrition management during plug production for Eustoma has not been well established. This study aimed to determine the effects of nitrogen (N), phosphorus (P), and potassium (K) concentration, and nitrogen form of nutrient solution during plug production on seedling growth at 25/20oC and subsequent plant growth and flowering performance of Eustoma ‘Claris Pink’ and ‘Rin’ grown in summer and winter.全株淨光合作用葉綠素螢光根活性植體分析養液whole plant net photosynthesischlorophyll fluorescenceroot activityplant tissue analysisnutrient solution
