The present experiment was conducted at the experimental farm of department of Floriculture and landscaping, Punjab Agricultural University from 2014-15 and 2015-2016 with the objective to study the morphological and floral variability in gladiolus variety ‘Punjab Glance’. The experiment was conducted in Factorial Randomized complete Block Design (...

The effect of gamma rays irradiation on vegetative characters of chrysanthemum variety 'Thai Chen Queen' was studied in this experiment. Four different doses of gamma rays (0, 10, 15 and 20 Gy) form 60Co source of ionizing radiation were used to irradiate rooted cuttings. Planting was done in earthen pots after irradiation and the experiment was la...

Five week old seedlings of Coreopsis lanceolata, Gaillardia aristata, Matthiola incana, Nemesia strumosa, Verbena hybrida and Viola tricolor were transplanted on five dates i.e. 20th October, 5th November, 20th November, 5th December and 20th December at 30x30 cm. The planting time significantly affected the plant growth and seed yield. The optimum...

The present investigation on variability, heritability, genetic advance in twenty three marigold genotypes was carried out for plant growth and flower yield. The highest value of PCV and GCV was observed for number of flowers per plant (117.95 and 116.50, respectively). High heritability was observed for days to bud initiation (98.48) followed by d...

Fifty seven genotypes of gladiolus were assessed for their efficiency with respect to yield and its contributing traits at PAU Ludhiana (Punjab). The higher PCV and GCV estimates were observed for the number of cormels plant−1, weight corm−1 and polar diameter of corm. High heritability with high genetic advance was registered for weight corm−1, sp...

Rooted cuttings of chrysanthemum variety ‘Otome Pink’ were treated with 0, 10, 15 and 20 Gy of gamma rays and evaluated for various morphological, palynological and anatomical characters. Plant survival, plant height, number of flower heads, stems per plant, stem diameter and leaves per plant reduced after gamma irradiation. The delayed flowering a...

To make the poplar (Populus deltoids) based agroforestry systems economically more profitable, twelve winter flower annuals under three environmental conditions (open, under 3 and 4 year old poplar canopy) with four replications in split-split plot design were evaluated. Results of the study revealed that yield and other parameters of flowering ann...

The seeds of Gaillardia aristata were packed in five different packaging material (cloth bag in desiccator, poly set bin, polyethylene bag - 600 gauze, cloth bag and aluminium foil) for a period of 18 months. The germination was recorded maximum (39.51%) in cold storage followed by ambient conditions (31.62%) and incubator (22.98%). Among the packa...

The seeds of coreopsis were stored under three storage conditions [cold storage (0-4°C and 90±2.7% RH), incubator (20-22°C and 75±1.5% RH) and ambient conditions] and packed in five different packagings (cloth bag in desiccator, cloth bag, aluminium foil, plastic bin, polyethylene bag - 600 gauze) for a period of 18 months. The highest germination...
