    abstract = {The objective of this study is to investigate the interaction of R, B and FR from phosphor-converted
LED on the growth and yield of the sweet basil and holy basil. Seedlings were grown in the chamber with a
continuous supply of 200 &#956;molm<sup>&#150;2</sup> sec<sup>&#150;1</sup> PPFD of R and B. Several ratios were applied as R:B.3.5 and 7.0
without FR and R:B.3.5 with FR 50 &#956;molm<sup>&#150;2</sup> sec<sup>&#150;1</sup>. The photo period was 16/8 h. The results found that R:B.3.5
with FR50 significantly increased the growth rate by 49-114%, the plant height by 64-137%, the stem diameter
by 20&#150;25% and the total fresh weight by 98-181% of the crops. R:B.3.5 with FR50 also significantly increased
the average leaf area by 59-85% for the holy basil but not in the sweet basil and increased the total
dry weight by 110<sup>&#150;2</sup>53% of the sweet basil but not in the holy basil. Additionally, no effects on the leaf
thickness of the crops were observed. R:B.7 without FR had the trend to promote the growth of leaf and stem
and total fresh weight of the crops than R:B.3.5 without FR. Moreover, the combination of FR with the R and
B light could increase the leaf expansion, stem length whole plant photosynthesis and total fresh and dry weight
of the sweet basil and holy basil.}
