Effect of IBA, types of Cutting and Rooting Media on Sprouting, Survival Percentage and Growth of Cuttings of Kartoli* (Momordica dioica Roxb.)

Abstract

Spine gourd is a perennial, dioceous climbing creeper belongs to family Cucurbitaceae and commonly known as Kartoli. The present study aimed to investigate the effect of different concentrations of IBA, types of cutting and rooting media on days required for sprouting, survival percentage growth of cuttings of kartoli. The cuttings taken from the tip, middle and basal portion of the vine were dipped into 250, 500, 750 and 1000 ppm of IBA (Indole-3-butyric acid) solution and planted in different rooting media such as Soil + Sand + FYM, Soil + Sand + Vermicompost and Soil + Sand + Cocopeat in 1:1:1 proportion. The experiment was laid out in Factorial Completely Randomized Block Design with two replications. The observations on days required for sprouting, survival percentage, length and number shoots and roots per cutting were recorded at 30 and 90 DAP. The data revealed that, the days required for sprouting, survival percentage and growth of cuttings of kartoli were found to be significantly influenced by the different concentrations of IBA, types of cutting and rooting media. Interactions between IBA concentrations (G), types of cutting (C) and rooting media (M), the treatment combination of G 4 C 1 M 1 recorded significantly minimum number of days (10.15) required for sprouting, the highest survival percentage (80.00) as compared with the remaining treatment combinations. The maximum length of main shoot and root were recorded in the treatment combination of G 4 C 1 M 1 (153.15 cm and 27.80cm), respectively and the highest numbers of shoots (6.10) and roots (132.80) per cutting were noticed in the same treatment combination as compared with the other treatments under study at 90 DAP.

Influence of Planting dates, Cutting types and IBA Concentrations on Rooting of Silvery (Leucophyllum frutescens)

“…The better percentage of cutting's survival might be ascribed with optimum time and IBA treatments aid to better root growth which amplified the absorption and transportation of nutrients from soil resultantly boost up plant metabolic processes (Singh, 2001). The results of current experiment are also in line with the data of the experiment of Padekar et al (2018) who reveals that, the semi hardwood cutting recorded significantly maximum survival percentage of 61.67 % as compared to the basal portion of the plant of momordica. Among the effect of IBA concentrations on survival percentage of momordica, the IBA at highest level of 10,000 ppm recorded significantly maximum survival percentage i.e.…”

“…The results of current experiment are like this might be due to exogenous auxin application to the cuttings, which might have brought early breakage of bud dormancy and resulted in early bud sprouting (Padekar et al, 2018). The earliest sprouting on semi hardwood cuttings might possibly be due to more absorption of nutrients and uptake of water from roots towards shoots (Mehta et al, 2016).…”

“…Singh and Chouhan (2016) also investigated maximum number of sprouted cuttings (6.62) under mid-august planting time and IBA concentration significantly increased the average maximum number of sprouted cuttings (4.47) at the rate of 2000 ppm in Phalsa cuttings Padekar et al (2018). indicated that, IBA at 750 ppm recorded significantly maximum number of shoots per cutting i.e.…”

Responses of Iba and Naa on Shoot and Root Growth of Semi Hard Wood Cuttings of Guggul [Commiphora Wightii (Arn.) Bhan.]

“…The lowest sprouting percentage (57.91) was recorded in the T 0 -control. The higher sprouting percentage with T 3 -IBA 750 ppm might be due to better root growth, which augmented absorption and translocation of nutrients from medium to the shoots, which might have taken active part in various plant metabolic processes (Padekar, 2018). The chlorophyll content was shown appreciable difference at 90 days after planting.…”
