Photosynthesis and Nitrogen Metabolism of Nepenthes alata in Response to Inorganic 𝐍𝐎_𝟑⁻ and Organic Prey N in the Greenhouse

Table 1

Total Chl content, Chl a/b ratio, total carotenoid content, and Chl/carotenoid ratio of leaf and pitcher of N. alata. The means and standard errors of four readings are given for each pigment. Letters represent comparison between leaf and pitcher. Any two means having a common letter are not significantly different.

Photosynthetic pigments	Leaf	Pitcher
Total Chl content (𝜇g/g FW)	1273.12 ± 46.80^a	266.39 ± 29.42^b
Chl 𝑎/𝑏 ratio	2.95 ± 0.04^a	2.01 ± 0.06^b
Total carotenoid (𝜇g/g FW)	207.11 ± 8.28^a	44.80 ± 5.00^b
Chl/Carotenoid ratio	6.15 ± 0.11^a	5.95 ± 0.04^a
