Varietal Variances in Photosynthesis and Transpiration Rates of Hibiscus Cannabinus L. (Kenaf)

Abstract

Kenaf (HIBISCUS CANNABINUS L.) is one of the important fiber crops next to cotton which is cultivated for its
core and bast fibres. For successful commercial cultivation of kenaf, we need to choose the proper
variety with most growth rate and biomass content. As growth and biomass production of plant are
strictly related to their physiology attribute, to meet this, we measured gas exchange characteristics of
three varieties of guantemala 4 (G4), V36 and kohn kaen 6(KK60) within characteristics, we measured
within four regular intervals of 30 days. The varieties showed different gas exchange pattern in each
stage of their growth. However, results of study showed that, there was no significant difference
between these three varieties in terms of their net photosynthesis (Anet) and transpiration rate.
