The effect of storage and different red and far red light treatments on Catalpa ovata g. don seed germination
Chinese catalpa is a medicinal and ornamental, low demanding tree which tolerates urban pollution, drought and poor soils. It should be planted more often in Serbia, and generative propagation is the most suitable method for mass production of this species. The aim of this research was to...

| description | Chinese catalpa is a medicinal and ornamental, low demanding tree which
tolerates urban pollution, drought and poor soils. It should be planted more
often in Serbia, and generative propagation is the most suitable method for
mass production of this species. The aim of this research was to investigate
the effects of red and far-red light on Catalpa ovata seed germination, as
well as the influence of seed storage length on germination. The seeds were
collected in 2003 and 2007 from the same tree, stored for one and five years
and exposed to red light (R) or far-red light (FR) before seed germination
tests. After one year of storage, seed germination was high (74-82%) in a
control treatment (white light conditions, 16h light and 8h dark), and the
seeds did not germinate in dark conditions. Red light and a combination of
red light and far red light treatments induced germination, but the obtained
values varied (7 - 66%) depending on the year of seed harvesting. The seeds
collected in 2003 had a higher germination percentage (51.0%) compared to
the germination of seeds collected in 2007 (up to 14%) after red light
treatment. The time of exposure to red light pulse (10, 15, 20 or 30 min)
did not considerably affect germination rate. After 5 years of storage,
germination percentage was considerably lower, reaching only 30% in white
light conditions. The results obtained in this research confirmed that C.
ovata seeds are photoblastic and can be stored for one year preserving a
high germination rate. |
