“…Paclobutrazol is a growth inhibitory compound that has been applied to inhibit the growth of cultures in in vitro culture. and in various plants, including fruit trees (Hasan et al 2013;Mendes et al 2021). The effectiveness of paclobutrazol concentrate in inhibiting plant growth depends on the physiological conditions of each plant and environmental conditions (Mog et al 2019).…”

The aquatic plant "Red Malang” (Ludwigia sp.) has a fairly high economic value as an ornamental aquatic plant, so it has the potential to be developed. The growth of in vitro cultures in culture bottles is high-speed, so it is necessary to find a formula media to inhibit growth so that the frequency of subcultures is reduced. The current research aims to produce a formula media for shoot multiplication and in vitro culture conservation. The research was carried out at the ICABIOGRAD tissue culture laboratory from April 2020 to June 2021. Research activities included plant propagation, conservation, and regeneration after conservation. Plant material was using in the form of a culture collection in the ICABIOGRAD tissue culture laboratory, treatment media for propagation were BA (0; 0.1; 0.3; 0.5; 0.7 and 0.9 mg/L) + thidiazuron (TDZ) (0 and 0.1mg/L). For conservation were MS + BA medium (0 and 0.1 mg/L) + paclobutrazol (0; 0.1; 0.3; 0.5; 0.7 mg/L) and for shoot regeneration after conservation using MS medium without Plant Growth Regulator (PGR). Data analysis using the Anova SAS version 9.0 test program. Further test using DMRT test with alpha level 5%. There was no difference in the mean value between levels of TDZ treatment on the number of shoots and leaves. The difference in the mean value between levels of TDZ treatment was very significant on shoot height, the number of roots, and root length. BA treatment with a concentration of 0.7 mg/L is better because it gives higher results for each observation variable. For conservation, treatment with paclobutrazol 0.5 mg/L inhibited shoot and leaf count, and 0.3 mg/L inhibited shoot formation. Cultures stored for six months grew normally after being regenerated. The highest shoots and the highest number of leaves were obtained from the treatment of paclobutrazol without BA. This study indicated that the propagation media of aquatic plants Ludwigia sp. did not require high concentrations of BA. Cultures could be stored for over six months using paclobutrazol with 0.3-0.6 mg/L.

“…Most of the research has involved the effect of the triazole, paclobutrazol, which has been registered for use in many countries (Yadava and Singh, 1998;Saran et al, 2008;Hasan et al, 2013;Shinde et al, 2015). Other growth regulators such as uniconazole and prohexadione-Ca have also been evaluated (Silva et al, 2010Mouco et al, 2013).…”

“…Flowering and fruit production are promoted, depending on the dose of the chemical, tree agronomy and the weather (Kurian and Iyer, 1993a,b,c;Burondkar et al, 1997Burondkar et al, , 2013Blaikie et al, 2004;Bithell et al, 2013;Hasan et al, 2013;Salvi et al, 2013;García de Niz et al, 2014;Narvariya et al, 2014;Shankaraswamy and Neelavathi, 2016). An analysis of production in Maharashtra in India indicated that the financial returns were more than 150% higher using paclobutrazol compared with standard growing practices .…”

Can the productivity of mango orchards be increased by using high-density plantings?

a b s t r a c tMango (Mangifera indica) trees are traditionally established at about 100-200 trees per ha and eventually grow into large specimens 10 m tall or more, making spraying and harvesting difficult. It also takes a long time to recover the initial costs of establishing and maintaining the orchard. There has been considerable interest in planting orchards up to 4000 trees per ha to take advantage of early production and to increase economic returns. However, trees planted at high density soon begin to crowd and shade each other and production falls. We reviewed the performance of high-density orchards in different growing areas, and the role of dwarfing cultivars and rootstocks, tree canopy management and the growth regulator, paclobutrazol to control tree growth. There has been no general agreement on the optimum planting density for commercial orchards which vary from 200-4000 trees per ha in different experiments. Some potential dwarfing material has been developed in India and elsewhere, but these cultivars and rootstocks have not been widely integrated into high-density orchards. Canopy management needs to take into account the effect of pruning on the regrowth of the shoots and branches, light distribution through the canopy and the loss of the leaves that support the developing crop. Pruning must also take into account the effect of vegetative growth on flower initiation. Annual light pruning usually provides better fruit production than more severe pruning conducted less regularly. There have only been a few cases where it has been demonstrated that paclobutrazol can counteract the negative effect of pruning on flowering and fruit production. There are also concerns with residues of this chemical in export markets and contamination of ground waters. The future development of high-density plantings in this crop is dependent on the use of dwarfing cultivars and/or rootstocks and better canopy management strategies. Dwarfing cultivars and rootstocks should provide small-to medium-sized trees with medium to large yields. This can readily be identified in experiments by examining the relationship between yield and tree growth. Research on canopy management should assess the impact of pruning on flowering, light distribution within the canopy and the leaf area supporting the developing crop. The productivity of mango is not likely to be increased by the use of high-density plantings without extensive efforts in plant breeding and canopy management.Crown
