Abstract
The study was accomplished at
‘2abiotech Lab’ of the horticulture farm of Sher-e-Bangla Agricultural
University, Dhaka to improve the flower production and quality of Rose with
pinching during the period of October to November, 2013. The study comprised of
four levels of pinching, namely control (P0), soft pinching (PS) - < 2 cm,
medium pinching (PM) – 4 cm and hard pinching (PH) – 8 cm. Significant
differences along with treatments were observed for evaluating all the
attributes. Leaf area and chlorophyll percentage were also significantly varied
at different treatments with days after pinching (DAP). Maximum chlorophyll
observation (54.5) was measured by medium pinching (PM) at 20 DAP. Whereas
minimum leaf area and chlorophyll percentages (25.2 cm2 and 39.7, respectively)
were recorded by control (P0) at 60 DAP. Maximum number of blind shoot (11.4)
was recorded by hard pinching (PH), whereas, minimum (5.4) by medium pinching
(PM). Highest number of flower yield (13.4) was recorded by medium pinching (PM),
whereas the minimum number of flower yield (5.3) by control (P0).
