dc.description.abstractABSTRACT The present research entitled “Studies on seed set and colchicine content in Gloriosa superba L.” was carried out in the experimental field as well as in laboratory of the Department of Forest Products, College of Forestry, Dr Y S Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during 2019-21. The study was conducted on morphology, phenology, floral biology, seed germination, pollination treatment and colchicine content in different parts of Gloriosa superba. The species was perennial in nature with climbing stem. Stem was cylindrical, weak, glabrous, sparsely branched arising from V or L shaped tubers. Leaves were simple, ovate to lanceolate, sessile, entire, glabrous, obtuse base with acuminate tips endings into tendrils. Flowers were greenish at first then yellow passing through orange to scarlet red colour at maturity. The maximum stigma receptivity was found on the day of anthesis and maximum anthers dehisced between 8:30- 9:30 am. The peak period of anthesis was found at the time of 8:30 to 9:30 am. In bed conditions, maximum germination percentage (64.80 %), height of seedling (18.35) cm, number of leaves per seedling (15.70), peak period of germination during fifth week was found in hot water without sarcotesta (T6) treatment, earlier germination initiation and minimum germination duration was recorded in conc. H2SO4 (T10). The maximum micro-tuber length and diameter (4.92 cm), (8.87 mm) of arm one and length and diameter of arm two (3.09 cm), (8.45 mm) was recorded in hot water without sarcotesta treatment (T6). Similarly, in pot condition, maximum germination percentage (62.40%), earlier germination initiation (32.60 days), height of seedling (18.05 cm), number of leaves per seedling (16.10), peak period of germination during sixth week was observed in hot water without sarcotesta treatment (T6) and minimum germination duration (30.30 days) was observed in PGPR-I (T2). The maximum micro-tuber length and diameter (4.56 cm), (8.35 mm) of arm one and length and diameter (2.64 cm), (7.89 mm) of arm two was observed in hot water without sarcotesta (T6) treatment. Weight of micro-tuber was recorded maximum (3.48 g) in bed as well as in pot condition (3.13 g) in treatment of hot water without sarcotesta (T6). Among different pollination methods, maximum fruit set (80.00 %), number of seeds per pod (43.73), pod length (6.04 cm), pod diameter (1.81cm), 100 seed weight (3.36 g), seed diameter (4.29 mm), extract percent (34.44 %), colchicine content (1.54 %) was noticed in assisted pollination treatment (T7). Assisted pollination method resulted in maximum amount of colchicine content in seeds (1.40 %) which was followed by pericarp (0.29 %), leaves (0.11 %) and stem (0.03 %). The seeds without sarcotesta also resulted in high percentage (0.94 %) whereas with sarcotesta value of colchicine recorded was (0.43 %).en_US
