what is the internodal length jasmine
Answers
Jasmine is one of the important commercial flower crop, grown for its white fragrant flowers, largely used for garland and floral decoration. The jasmine belongs to family ‘Oleaceae’. A study on the effects of four growth regulators viz., NAA, cycocel, gibberellic acid and ethrel each at two concentrations was carried out on Jasminum auriculatum Vahl. in the Floriculture Unit of the Department of Horticulture, College of Agriculture, University of Agricultural Sciences, Dharwad during 2005-06. The main objective was to evaluate their effects on growth, flowering and yield of Jasminum auriculatum Vahl. GA3 at both the concentrations significantly increased primary and secondary lateral shoot length, GA3 gave more number of internodes and the enhancing the internodal length. GA3 increased the length and width of the leaves with an associated increase in the total leaf area and slightly reduced number of leaves. Cycocel and ethrel were equally effective in increasing the number of productive shoots closely followed by NAA. Reduced number of productive shoots was observed under high concentration of gibberellic acid. Cycocel at 500 ppm induced early flowering and registered longer duration of flowering. Cycocel at 500 ppm recorded highest yield in terms of both weight and number of flowers, whereas both the concentrations of GA3 registered lowest values. Cycocel at 500 ppm recorded highest length of flower bud and increased the weight of hundred flower buds, whereas both the concentrations of GA3 recorded lowest length of flower bud and reduced the weight of hundred flower buds. Cycocel at 500 ppm increased chlorophyll ‘a’ content whereas ethrel at 100 ppm increased chlorophyll ‘b’ content. The total chlorophyll content was maximum with cycocel at 500 ppm.
Answer:
The leaves and stem together are called
the shoot. shoots can be separated into long shoots and short shoots on the basis of the distance between buds ( internode length).
