“…The increases in dry weight of roots have directly influenced the length of roots, and the number of roots. The present findings are in conformity with the results in dragon fruit (Rahad et al 2016, Chahal 2020, Dhruve et al 2018, pomegranate (Deshmukh et al 2019), and mahogany cuttings (Sondarva et al 2017).…”

The present study was carried out at the Fruit Nursery, Department of Fruit Science, Dr Panjabrao Deshmukh Krishi Vidypeeth, Akola.With the aim to investigate the effect of various compositions of soil media and to find the proper composition for better rooting of dragon fruit cuttings. The design of experiment was CRD with five replications consisting of seven treatment combinations viz., T1-Soil:Sand:FYM, T2-Soil:Red Soil:FYM, T3-Soil:Silt:FYM, T4-Soil:Sand:Vermicompost, T5-Soil:Red Soil:Vermicompost, T6-Soil:Silt:Vermicompost with ratio of 2:1:1 and T7 was control (100% Soil). All the data were recorded on different growth parameters of selected representative cuttings which were selected at random from each replication. Treatment T5 i.e. Soil:Red Soil:Vermicompost in ratio 2:1:1 displayed superior performance articulated in terms of root growth parameters viz., number of root per cutting (58.2), root length (21.54 cm), root diameter (2.36 mm), length of longest root (23.66 cm), average number of roots (53.62), average length of root (20.96 cm), root volume (1.82 cc), fresh weight of root (5.18 g), dry weight of root (0.86 g) and survival percentage (97.59%) among different treatments for successful propagation of dragon fruit cuttings.

“…On the other hand, the number of new shoots differed among genotypes (P<0.05). A previous study reported that dragon fruit with red-pulped fruits generated a higher number of new shoots than the white-pulped genotypes under no auxin treatment [10]. In our study, the lower number of new shoots for the 'White' genotypes may be related to ant infestation.…”

“…However, effects observed on root performance of H. undatus were a result of the application of high concentrations of auxins. Previous studies found that the application of IBAwas effective at a concentration ranging from 6000 ppm to 7000 ppm [9][10]. These concentrations are surprising given the knowledge that auxins are effective even at very low concentrations and auxins applied at high dose may actually be damaging [11].…”

“…In fact, a study on cactus pear showed that the root length decreased with increasing concentrations of auxins from 5,000 mg.l -1 to 10,000mg.l -1 [15]. Moreover, the high auxin concentrations (6000 to 7000 mg.l -1 ) used from previous studies on dragon fruit did reveal significant responses between white and red-pulped varieties of dragon fruit [9][10].…”

Information is limited on the effects of commercial plant growth regulators (PGRs) on dragon fruit. Most studies on rooting effects on dragon fruit cuttings employed very high doses of plant growth regulators (PGRs), which are not deemed practical for greenhouse and field applications. This study was initiated to evaluate the responses of four genotypes of dragon fruit (‘Royal Red’, ‘Moroccan Red’, ‘Mexican White’, and ‘Hawaiian White’) during greenhouse acclimatization to diluted concentrations of commercial PGRs that are readily available in the market. A single factorial experiment on genotype effects on root and shoot responses, without PGR, was conducted. A second experiment with a 4x3x2 completely randomized design, with four genotypes, three diluted commercial PGR formulations and two exposure times as factors was also done. Root length, number of roots, number of days to first shoot emergence and number of new shoots were measured after 50 days of acclimatization in the greenhouse. In the single factorial experiment, only ‘genotype’ had an effect on number of new shoots (P<0.05). In the multifactorial experiment, all factors tested did not have significant interaction effects. However, the main effect of ‘genotype’ on number of new shoots and number of days to first shoot emergence was also significant (P<0.05). The lack of significant effect of other factors and their interactions on most growth responses suggest that it is difficult to resolve differences among the four genotypes using highly diluted commercial PGR formulations after a 50-day observation period. However, our data still suggest that the ‘Red’ genotypes are more superior than the ‘White’ genotypes in terms of shoot growth.

“…It is believed that the greater number of shoots observed in cuttings treated with the biostimulant SprintAlga TS®, especially for Brewer's Gold, may be related to the presence of hormones that have an effect on plant growth such as cytokinins (CALVO et al 2014, MICHALAK et al 2016. It was observed in other studies that cuttings treated with cytokinins such as Benzyladenine present a greater number of shoots (ELOBEIDY 2006, DHRUVE et al 2018, SIDDIQUA et al 2018.…”

The aim of this work was to evaluate the effect of different cutting lengths, the use of biostimulants and diameter of cuttings on hops vegetative propagation. The work was conducted in a greenhouse at the Center for Agricultural Sciences (CCA) at the Federal University of Santa Catarina (UFSC), in Florianópolis/SC, Brazil, between October 2019 and January 2021. In experiment 1, cuttings with one, two and three buds were tested, with and without application of biostimulant SprintAlga TS® (Biolchim) in Brewer's Gold and Cascade cultivars. In experiment 2, cuttings with diameter of 1.5 cm, 2.5 cm and 3.5 cm were tested for Northern Brewer cultivar. In both experiments, survival, rooting, root length, root quality, number of shoots and shoot length were evaluated. In experiment 1, Cascade had lower survival, rooting and development compared to Brewer's Gold. The use of biostimulant increased survival and rooting rates of both cultivars. For Brewer's Gold the use of biostimulant improved root quality and increased shoot number, root and shoot length. For Brewer's Gold, 3-bud cuttings improved root quality and increased number of shoots. For Cascade, 1-bud cuttings showed the highest survival, rooting and development rates. In experiment 2, the highest rates of survival, rooting and the longest root length were obtained with 1.5 cm diameter cuttings. Larger diameter cuttings (2.5 and 3.5 cm) produced fewer shoots, but longer shoots.
