為探討花粉來源對茂谷柑果實品質之影響，2005年進行開放授粉、自花授粉、不授粉及授海梨柑花粉4等種處理，2006年進行授海梨柑、柳橙、桶柑花粉、自花授粉及開放授粉等5處理，結果顯示茂谷柑具自交親合性且有單為結果能力，而授海梨柑及柳橙花粉明顯增加著果率（21.3％至25.8％），自花授粉果重較輕且種子數較少（8.9－10.4個）。
The purpose of this study was to find the effects of pollen source on fruit set and fruit quality in 'Murcott'. We compared open pollination, self artificial pollination, bagging with emasculation and cross-pollination with 'Hai-li' tangor in 2005, and compared cross-pollination with 'Hai-li' tangor, 'Liu-chen' orange, 'Tankan' tangor, self artificial pollination and open pollination in 2006. 'Murcott' was found to be self-compatible and has parthenocarpic ability. Pollination with 'Hai-li' and 'Liu-cheng' pollen produced a significantly higher fruit set (21.3%-25.8%). Self artificial pollination significantly decreased fruit weight and seed number (8.9-10.4 seeds per fruit)
