Abstract
The present investigation on the "studies of packing, storage and chemical on growth and development of gladiolus (Gladiolus spp)" was carried out at College of Horticulture, Pune. Design of the experiment was randomized block design. These studies were carried out with the objective of breaking dormancy of gladiolus by using various conventional methods, cold storage and plant growth regulator, so as to test the effect of all these treatments on further growthand development. Data were recorded for the characters namely; time taken for50 % sprouting, number of corms sprouted, days to 50 % flowering, plant heightat flowering stage, spike length, rachis length, number and size of florets, numberof corms and cormels produced per plant, weight of corms and vase life.Results obtained from these nvestigations indicated that the conventionalmethods such as 0 % ventilation, 0.5 % ventilation, 1 % ventilation, sphagnummoss storage + periodic dipping in tap water were at par with the performance of cold storage. As far as weight reduction, at time of planting was considered, coldstorage had shown 19.48 % reduction followed by 0 % ventilation (18.65 %).Control had shown only 11.82 % reduction. Time taken for 50 % sprouting was the shortest for cold storage followed by sphagnum moss + periodic dipping in water. Number of corms sprouted was 100 % in almost all treatments except in 0 % entilation, GA3 and 0.5 % ventilation. Rotting was observed in these two ventilation techniques. It was due to entrapped respiratory moisture. Time taken for 50 % flowering was the lowest in cold storage followed by 0 % ventilation, sphagnum moss + periodic dipping in water and 0.5 % ventilation. Plant height and length of spike were the highest in control. Rachis length was the highest in the sphagnum moss + periodic dipping in water followed by 1 % ventilation. Size of florets was the highest in 0 % ventilation followed by cold storage. Number of spikes was the highest in 0.5 % ventilation followed by cold torage. In the present studies number of corms per plant and weight of corms per plant were the highest in cold storage, followed by 0.5 % ventilation and 0 % ventilation. Cormel production was the highest in 0 % ventilation followed by cold storage. Vase life in plain water was shorter than that in distilled water. Cold storage treatment and 0 % ventilation showed more vase life. These results indicate that conventional methods of high temperature storage were at par with the non-conventional ethods.
