摘要

夜間日光燈照已證實能影響印度棗之開花及產期，惟不同的光源間可能有不同的影響，因此本試驗以日光燈、鎢絲燈、植物燈、太陽燈，以及不照光（對照）等5種處理， 探討其對高朗1號及特龍印度棗生育之影響，以提供學者研究及農民採行之參考。試驗採用逢機完全區集設計，4重複，燈照處理者自6月25日開始，每日於日落後照射12小時，共照射40日。試驗結果顯示，經日光燈、植物燈、鎢絲燈、太陽燈等四種光源光照處理者皆能促進植株提早開花、增加開花數、增加早期著果數及提早產期。施以日光燈及植物燈光照處理者與無光照者其產量較高，而經鎢絲燈及太陽燈處理者其產量較低。鎢絲燈與太陽燈處理及日光燈與植物燈處理者，其產期較未經光照處理者分別提早50及45日。基於光照成本及產量之考量，在本試驗中日光燈乃是最適當之照射光源。

Fluorescent light applied in the night forcing the flower and earlier bearing of Indian jujube had been proved. However, light sources might also have various effects on the flowering and bearing in Indian jujube. Four kinds of light resources including fluorescent, floral, solar, and incandescent lamps were used to investigate the flowering and yielding responses of Telong and Kaolang 1. A random complete block design with 4 replications was used in this study. Treated plants were lighted for 12 hours from the evening and started from 25th of June in 1996 for 40 days.Results showed that the earlier flowering, increasing number of flower and fruit sets, and earlier bearing were found for plants treated four light sources. Higher yields were found for plants lighted with fluorescent, floral light and control. Plants treated with solar and incandescent lights showed lower yield. Yielding date can be advanced 50 and 45 days when plants treated with solar, incandescent and fluorescent, floral lights, respectively. Considering the costs of lighting and yield of Indian jujube, the fluorescent lamp was the most suitable light source in this study.
