ABSTRACT
Mulberry (Morus alba L.) belongs to the family moraceae. Mulberry is the basis for commercial sericulture since
mulberry leaf is a natural and sole food for silkworms (Bombyx mori L.). Triazoles compounds are widely used
systematic fungicides to control diseases in plants and animals. The fungicides triademefon (TDM) 15 mg L−1
and paclobutrazol (PBZ) 12 mg L−1 were used by soil drenching on 70, and 120 days after planting. The effects of
different concentration of triazoles (TDM and PBZ) compounds increased total chlorophyll, carotenoid content,
intercellular CO2 concentration, net photosynthetic rate (PN), water use efficiency, total root length, dry weight,
and moisture content. On the other hand, petiole length, total leaf area, stomatal conductance, transpiration
rate (TR) were decreased. Among the triazole compounds PBZ showed higher effectiveness than the other
two triazole compounds. It is concluded that triazoles are able to protect plants from the environmental stress
conditions in mulberry varieties.
