“…There are others that are resistant to diseases such as mango wilt caused by the fungus Ceratocystis fimbriata (Rossetto et al, 1997;Arriel et al, 2016). In studies conducted in northern Australia with rootstocks from 95 poly-embryonic cultivars there was no clear relationship between dwarfing in the field and the vigour of the trees in the nursery (Bithell et al, 2016). These data highlight the difficulty in assessing the potential of rootstocks for dwarfing.…”

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

“…Root distribution patterns are considered essential to aid in the selection of rootstocks (Black et al, 2010) [3] . The root distribution pattern of trees varies from region to region and it is influenced by species, age of the tree, season, soil properties and other cultural practices (Singh et al, 2012) [12] .The structural relationship between the rootstock and scion shows the relationship between vigour reduction of rootstocks and dry matter content of the root (Bithell et al, 2016) [2] . Several previous reports are available to determine the cashew rooting pattern (Tsakiris and Northwood, 1967;Vidyadharan and Peethambaran, 1979;Harishu Kumar and Khader, 1985;Khader, 1986;Wahid et al, 1989, Salam et al, 1995and Yadhukumar, 2001) [13,14,5,6,15,10,17] but not to compare rootstocks.…”

The present investigation on the root distribution pattern of cashew rootstocks was carried out at ICAR-Directorate of Cashew Research (DCR), Experimental Station, Santhigodu, Karnataka. The study aimed to understand the root distribution of two dwarfing rootstocks (NRC 492, Taliparamba-1) and one vigorous rootstock (Vengurla-4) of eight-years-oldcashew tree, as determined by the root excavation method. The root samples were collected vertically from different depths (0-200 cm) and laterally at different distances (0-300 cm) from the tree trunk. Results indicated that the root distribution pattern showed significant genotypic variation. Regarding the vertical distribution of roots, 95 percent of the roots were distributed in 0-100 cm horizons, while very few roots were in the 100-200 cm horizons. In the lateral distribution, 97 percent of root density was in the 0-200 cm area from the tree trunk. Vengurla-4 (vigorous rootstock) had a higher root length, root volume and two-fold increases in total root production compared to dwarf rootstocks. PCA study revealed that the selection of rootstocks based on tree height, TCSA, canopy spread, lateral and vertical distribution of roots represent the main morphological indices for evaluating the effect of cashew rootstocks.
