Abstract

Aim: To study the influence of seed priming on the pattern of capsule and seed development in sesame.

Place and Duration of Study: The field experiment was conducted during the pre kharif seasons of 2017-2018 and 2018-2019 in sesame variety Savitri at AB Block farm, Bidhan Chandra Krishi Viswavidyalaya, Kalyani, Nadia, West Bengal, India.

Methodology: Experiment was laid out in split plot design with 3 replications. Ten schedules of seed priming viz T1 (KNO3 @ 10 mM), T2 (KNO3 @ 20 mM), T3 (KNO3 @ 50 mM), T4 (KH2PO4 @ 50 mM), T5 (KH2PO4 @ 100 mM),T6 (KH2PO4 @ 200 mM), T7 [Polyethylene glycol (PEG) 6000 @ -0.4 MPa], T8 [Polyethylene glycol (PEG) 6000 @ -0.3 MPa], T9 [Polyethylene glycol (PEG) 6000 @ -0.2 MPa], T10 Distilled water (Hydro priming) along with control T11 (Dry seed) were taken as main plot treatment and stage of harvest was considered as sub plot treatment. The pattern of capsule and seed development was studied at 10 days after anthesis (DAA), 20 days after anthesis (DAA), 30 days after anthesis (DAA), 40 days after anthesis (DAA) and 50 days after anthesis (DAA) interval. Ten plants from each replication and in each treatment were selected at random to record data on morphological and physiological characters.

Results: Fresh capsule length, fresh capsule breadth, fresh capsule weight, fresh seed weight and dry seed weight showed a steady increase up to 40 days after anthesis (DAA) then decreased slowly up to maturity.

Conclusion: Considering seed yield and quality parameters, T7 [Polyethylene glycol (PEG) 6000 @ -0.4 MPa] and T9 [Polyethylene glycol (PEG) 6000 @ -0.2 MPa] appears to be ideal among the treatments for quality seed production in sesame.

Keywords:
