Analysis of Photosynthetic Characteristics and UV-B Absorbing Compounds in Mung Bean Using UV-B and Red LED Radiation

Table 3

Effects of red LEDs and UV-B on the photosynthetic characteristics of the mung bean.

Duration	Treatment	Photosynthesis	Stomatal conductance	Water use efficiency
		(𝜇mol/m^2/s)	(mmol/m^2/s)	WUE
20 d	CK	4.85	77.3	6.5
	L	5.62*	90.6*	9.8*
	U	4.63	75.9	7.0
40 d	CK	6.23	110.7	13.3
	L	7.49^#	142.3^#	19.6^#
	U	5.33^#	90.8^#	9.1^#

Note: different letters followed the data of same index at the same treatment time indicate significant difference among treatments. Means with asterisk (*) or pound sign (^#) were significantly different at the 𝑃<0.05 level (𝑛=6) according to Duncan’s multiple range test (*𝑃<0.05; ^#𝑃<0.05).
