Abstract:
A factorial based on RCBD
experiment was conducted to evaluate the
effects of priming and foliar spray of
cycocel on rapeseed yield components.
Treatments were included; seed priming (0,
600, 900, 1200, 1500 μM) and foliar spray
(0, 600, 1200 μM) with cycocel at
development stage of flower buds. The
results revealed that seed priming with
cycocel significantly increased emerged
plant number per plot, silique dry weight in
the main stems and branches, plant dry
weight, branches number, silique number in
the main stems and branches, seed number
in branches, 1000 seeds weight, and seed
yield in non-stress conditions. Foliar
application with cycocel also increased
plant dry weight, 1000 seeds weight in
branches, harvest index and seed yield.
Moreover, interaction effect of priming and
foliar application of cycocel increased plant
dry weight and 1000 seeds weight with
branches. CCC foliar application during the
early stages of reproductive stage went to
elevated plant dry weight and 1000 seeds
weight in auxiliary branches and, also
increased harvest index and grain yield.
Mean comparison and interaction effects of
traits also revealed that, appropriate levels
of CCC had the meaningful effects on any
agronomic and physiological trait. However,
the most meaningful impact in most traits
was traced in case with primed seed with
900 and 1500 μM CCC. Overall, owing to
the present data, CCC priming under both
normal and harsh conditions may raise the
germination related traits, seedling
establishment, plant growth and ultimately
may goes to increased yield.
