SALT
TOLERANCE OF PHYSALIS DURING GERMINATION AND SEEDLING GROWTH
ERTAN
YILDIRIM1* HUSEYIN KARLIDAG2 AND ATILLA DURSUN1
Abstract:
The
study was conducted to evaluate the effect of NaCl salinity on
germination and emergence of Physalis ixocarpa and Physalis
peruviana. Seeds of P. ixocarpa and P. peruviana were
germinated by the use of 0, 30, 60, 90, 120 and 180 mM NaCl solutions in
petri dishes. Final germination percentage (FGP) decreased with the
increase in NaCl concentration. Both species germinated at the ranges of
salinity. P. peruviana gave the greater germination percentages
under salt stress than P. ixocarpa. NaCl salinity at different
concentrations adversely affected germination rates. For seedling
growth, seeds of both species were sown at 10 mm depth in plastic trays
filled with peat to determine final emergence percentage (FEP). The
trays were irrigated manually to saturation every day with 0, 30, 60,
90, 120, 150 or 180 mM NaCl solutions to maintain the level of salinity.
Salinity affected seed emergence and seedlings growth more than seed
germination. The study showed that no emergence of Physalis was
observed at 90, 120 and 180 mM NaCl salinity. Fresh and dry weights of
normal seedlings were also evaluated. Salt stress significantly
decreased the plant fresh and dry weight of both species. Based on the
results of the experiment, it can be concluded that seedling emergence
and growth is more sensitive to salt stress than seed germination in
Physalis.
