Abstract
Hot pepper (Capsicum chinense Jacq.) is an excellent source of capsaicinoids for many industrial uses.
It has been demonstrated that a higher carotenoid content is found in greenhouse and shadehouse pepper (C. annuum) fruits as compared to open-field production.
However, there is limited information on dry fruit yield and pungency of C. chinense under protected cultivation.
This investigation identified the responses of capsaicinoid yield in Capsicum chinense genotypes under greenhouse (GH) and shadehouse (SH) environments.
The hot pepper genotypes, ‘Akanee Pirote’, ‘Phet Mordindang’, ‘Tubtim Mordindang’, HB1, HB2, HB3, and HB4 were developed at Khon Kaen University, Thailand for high pungency and high fruit yield, while ‘Orange Habanero’ and ‘Super-hot’ are commercial cultivars used as cultivar checks.
The results revealed that the environmental factors between the GH and the SH were very different, and they affected fruit number, dry fruit yield, capsaicinoid amounts, and capsaicinoid yields.
In general, the pepper plants grown under the GH environment produced greater fruit numbers, higher dry fruit yields, higher capsaicinoid content, and higher capsaicinoid yield than those plants grown under SH conditions.
However, hot pepper genotypes did have different responses in each environment. ‘Phet Mordindang’ and ‘Akanee Pirote’ produced the highest capsaicinoid yields under GH condition (1,031.6 and 1,009.6 mg plant-1, respectively), while those plants under SH condition produced 307.6 and 125.1 mg plant-1, respectively.
The capsaicinoids production under protected environments found in this study is important information for Capsicum production of high value market of pharmaceutical extract products.
