“…In the natural environments, low or high temperatures usually influence negatively plant photosynthesis (Zinn et al 2010, Rahman 2013. As a primary source of energy for carbon fixation, light has also been thought to be one of the main factors affecting photosynthesis and causing photoinhibition of PSII (Fukuda et al 2008, Weng et al 2013.…”

The chilling and light stresses were experimentally created to explore photosynthesis of Fraxinus mandshurica seedlings in northeast China. Net photosynthetic rate, stomatal conductance, and transpiration rate decreased significantly with the decline of temperature and light. Significant interaction effects of light and chilling were observed on gas exchange of photosynthesis. The minimal fluorescence yield of the dark-adapted state (F 0) increased with increasing light and decreasing temperature. Both high and low light stresses induced the decreases of the maximal quantum yield of PSII photochemistry (F v /F m), photochemical quenching coefficient (q P), nonphotochemical quenching (NPQ), and electron transport rate. Decline of F v /F m and increased F 0 were observed under decreasing temperatures. Decreased NPQ and q P at frost temperature suggest that F. mandschurica failed to dissipate excess light energy. No interactive effects of chilling and light on chlorophyll fluorescence parameters suggests that F. mandschurica seedlings might be adapted to combined stresses of light and chilling.

“…When CO2 exchange is inhibited, such as during low temperatures, energy consumption is reduced (Baker 1993, Leegood 1995. Thus, both high irradiance and low temperature can cause damage to the PSII of plants (Weng et al 2013, Huang et al 2016, Lin et al 2021. A reduction of Chl content reduces the ability of leaves to absorb photons as well as changes in the light-harvesting apparatus and the efficiency with which absorbed photons are subsequently used in photosynthesis (Peng et al 2002, Goh et al 2009, Yang et al 2020.…”

“…Pongsomboom et al (1992) found that net CO 2 assimilation (A) in 'Nam Dok Mai' growing in a glasshouse was higher at day/night temperatures of 30 • /20 • C than at day/night temperatures of 15 • /10 • C. Weng et al (2013) showed that saturated values of A were 5.7, 7.2, 9.6, and 11.8 mol CO 2 per m 2 per s at 13 • , 18 • , 24 • and 30 • C, respectively. Researchers in Japan showed that at a vapour pressure deficit (VPD) of 1.5 kPa, A was higher in 'Irwin' trees growing at 40 • /25 • C than at 30 • /25 • C (Talwar et al, 2001).…”

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
