چکیده
Seasonal variation (e.g. temperature and photoperiod) between growing seasons might affect
inulin content and inulin yield of Jerusalem artichoke. However, there is limited information on
genotypic response to seasons for inulin content and inulin yield. The objective of this study
was to investigate the variability in genotypic response to seasons for inulin content and inulin
yield of Jerusalem artichoke. Field experiments were conducted during the early-rainy season
from June to September 2011 and the post-rainy season from September to December in 2011
and these 2 seasons were repeated in 2012 at the Field Crop Research Station of Khon Kaen
University. A randomized complete block design (RCBD) with 5 replications was used. Four
Jerusalem artichoke genotypes were studied during both seasons in each year. Data were
recorded for brix value, inulin content, tuber yield, inulin yield, biomass and harvest index at
harvest. The results revealed that seasonal variations had significant effects on inulin content,
inulin yield, tuber yield, biomass and harvest index but not on brix value. The results indicated
that growing Jerusalem artichoke in the early-rainy season with high temperature and long
photoperiod resulted in greater inulin content and biomass. In contrast, growing Jerusalem
artichoke in the post-rainy season with low temperature and short photoperiod resulted in
greater tuber yield and inulin yield. The present study revealed that temperature and photoperiod
were important for producing tuber yield and inulin yield. This information can be used to select
the appropriate growing seasons for sustainable production of inulin content, inulin yield and
tuber yield of Jerusalem artichoke in Thailand.
