Fifteen cultivars of spray chrysanthemum were evaluated in polyhouse and open-field, with three planting dates from mid-July to mid-August during 2003-05. Overall plant growth, flower stem length, number of flowers per plant, shelf life and vase life of flower were found to be maximum under 15th July planting compared to 30th July and 15th August plantings both under polyhouse and open-field conditions. Flower size and flower yield (g/plant) was highest under 30th July planting in polyhouse condition, whereas, in open-field it was the 15th July planting. Early flowering was recorded in 15th August planting both in polyhouse and open-field. Cultivar Arati showed maximum flower stem length and flower yield. Some of the other cultivars, viz., Yellow Anemone, Sarad Mala, Apsara Violet and Aditi also exhibited high yield both under polyhouse and open-field conditions. Polyhouse always recorded higher yield than open-field. Cultivar Yellow Anemone planted on 15th July recorded highest number of flowers per plant regardless of growth environment. Highest flower yield (794.94g) per plant was recorded in cv. Arati in 30th July planting under polyhouse, while, it was maximum in 15th July planting in open-field.Keywords

An investigation was undertaken to study the yield and yield components of spray-type chrysanthemum cv. Amal under variaous sources of nitrogen. The treatments considered different levels (100%, 75%, 50% or 25%) of four sources of nitrogen viz., urea, calcium ammonium nitrate, mustard cake and neem cake, alone or in combination of two or more of these. Results revealed that maximum stem length (62 cm) of cut flower and flower yield, number of flower heads (6387) and weight (4071.48 g/sqm) were mostly achiveved by application of total recommended dose of nitrogen through a combination of 25% N as neem cake + 25% N as mustard cake + 25% N as CAN + 25% as urea, and the treatment increased flower yield by 57.96% over treatment with nitrogen solely through urea. Flower size, individual flower weight, shelf and vase life of flower as well as anthocyanin content in floral tissue were higher in combined application of all oil cakes and urea and maximum under treatment combination of 50% recommended dose of nitrogen supplied through mustard cake, 25% N through neem cake and 25% N through urea. Anthocyanin content of flower tissues increased gradually upto 20 days from opening of the flower and, thereafter, declined sharply.Keywords

An experiment was undertaken to develop an improved in vitro regeneration protocol in gerbera. Murashige and Skoog (MS) medium was supplemented with various growth regulators at different concentrations for callus induction and organogenesis. Newly emerging leaves of Gerbera cv. Rosalin were used as explants. Experimental results showed that maximum rate (74.07%) of formation of callus with good growth was recorded on MS medium supplemented with 2.0mgL-1 2,4-D + BAP 0.5mgL-1. Best shoot regeneration (57.8 %) with maximum shoot number (12.0) was achieved on with BAP 2.0mgL-1 + NAA 0.5mgL-1 fortified MS medium. Maximum (66.7 %) and earliest (12.3 days) ischolar_main formation in shoots was recorded on IBA 3.0mgL-1 is 1/2MS media. Survival rate of regenerated plantlets was maximum (73.33 %) in the potting mixture containing garden soil, sand and vermicompost (1:1:1).Keywords
