Vrugk/eur van Mauritius en Madras (Red McLean) lietsjies word uitgebeeld oar ‘n reeks monsterdatums. Elke monster vrugte by beide kultivars se gemiddelde vrugmassa en die verhouding fatale oplosbare vastestowwe tot die persentasie suur is bepaal.
Summary:
The study compares fruit color and internal quality ripeness of Mauritius and Madras Red McLean litchi cultivars over a series of sampling dates.
Fruit samples were taken weekly from mature litchi trees to assess external fruit color, fruit mass, and the ratio of total soluble solids (TSS) to percentage acid.
External fruit color was visually assessed and photographed immediately after harvesting for both cultivars.
Internal ripeness was determined by calculating the ratio of TSS (total soluble solids) to acid percentage, which correlates with fruit sweetness and maturity.
The average fruit mass of 30 fruit samples per cultivar was measured and compared.
Some Mauritius fruits were bagged with specially made brown litchi paper bags right after the normal November drop to compare the effects of bagging on fruit color and ripeness versus unbagged fruit.
Graphical data shows how fruit mass and internal ripeness (TSS/acid ratio) developed over six sampling dates for both cultivars.
The study indicates differences in ripening characteristics between the two cultivars in terms of both external color and internal maturity.
Bagging of Mauritius fruit had an effect on fruit coloration and internal quality compared to unbagged fruit.
The article provides insight into the ripening process and quality variation of litchi cultivars relevant to harvesting and marketing decisions.
