Response of Plant Growth Substances and Bio-enhancer on the Enhancement of Bulblet Growth under the In-vivo Condition of Lilium

Lilies are one of the most extensively sold cut flowers due to their quantity and variety colours [1]. This this study aims at development bulbs from microbulblets by use different bio-enhancers growth substances decrease time for bulblet bulb ontogenic development. The experiment was carried out in Department Horticulture, Sikkim University year 2016-2017 find effect bio enhancers on enhancement vivo condition Lilium spp. conducted using completely randomized block design (CRD) which replicated thrice details treatments were as follows: T1-Paclobutrazol @10ppm, T2-Paclobutrazol @20ppm, T3-Paclobutrazol @ 30ppm, T4-Thiourea T5-Thiourea T6-Thiourea @30ppm, T7-Cow urine @10%, T8- Vermiwash @100%, T9- @50% T10- Control. sprayed 15, 30 45 days intervals. Among all used microbulblets, performance substance found more effective. treatment thiourea @30ppm (T6) paclobutrazol 20ppm (T2) recorded maximum weight (1.38g 1.27g respectively while @20ppm observed length (20.01 cm) breadth (15.46 after 90 spray under. However, organic like vermiwash 100% (T7) 50% (T8) par with @20ppm. root (7.70 shoot (17.38 given (T6). amount carbohydrate accumulated (76.31 mg/g) 10ppm (T4) 60 treatments, (T8). After concentration carbohydrates did not differ significantly where value 78.97 mg/g cow @10% (T7). Maximum moisture content @10ppm (65.76%). Keeping view results obtained regeneration scale can be substitutes chemical farming recommended farmers.
