Climatic Factor Differences and Mangosteen Fruit Quality between On- and Off-Season Productions

Abstract

The objective of this study was to investigate the differences in climatic factors and fruit quality between on- and off-season production periods. Climate, soil, and mangosteen measurements were all studied during on- and off-season production. We chose 40 mangosteen trees and observed flowering and fruit set rates over two production periods. The results showed that the number of flowers per branch, the number of fruits per branch, the circumference of fruits, and the fruit weight were higher during the on-season mangosteen production period than during the off-season mangosteen production period. However, the number of edible pulp segments, peel thickness, percentage of translucent flesh, and fruit gumminess were lower in the on-season mangosteen production period than in the off-season mangosteen production period. The percentage of fruit scars did not differ between the on- and off-season mangosteen production periods. When compared to the on-season mangosteen production period, there was lower relative humidity, soil moisture at 120 cm depth, and leaf wetness at 15 cm above ground during the off-season mangosteen production period; however, there was higher air temperature, soil moisture, and soil temperature at all four depth levels.

Potential development of mangosteen (Garcinia mangostana L.) through optimizing land use in Pati, Central Java, Indonesia

“…The period of bearing fruits: on season. At the eastern areas, on season period starts from September and harvest time starts from April to June [39] Fruit production: 300 kg/tree/year. Productivity of Gunungsari mangosteen is higher than the average productivity of mangosteen in Indonesia in 2021 about 112.…”

“…34 kg/tree [7]. When compared with mangosteen production in the off season, breeding mangosteen in the off-season produced heavier fruits [39] The main characteristic of Gunungsari mangosteen is the seed which soft or tender. Moreover, the seeds are flat-shaped and there are not even seeds inside the aril (flesh of fruit).…”

Mangosteen Yield and Fruit Quality under Regulated Irrigation with Sensors and IoT

“…With a colossal planting area of 67,151 hectares and an annual yield of 340,000 tons, Thailand stands unchallenged as the world's top mangosteen supplier, with China receiving most of its exports. [22]. Mangosteen is a perennial plant with a dark brown bark that produces purple-red skin fruit with edible white, soft, juicy, sweet, and acidic pulp [23].…”

“…At the same time, the phloem plays an essential role in fruit expansion, carrying dissolved sugars, acting as an osmotic attractant, drawing water into the developing fruit cells, and contributing to their juiciness [29]. Like other tropical fruits, low soil moisture in a root area induces mangosteen flowering [22]. Soil temperature is important for mangosteen nutrient transformation and uptake by roots, vegetative growth, and reproduction regulated by various factors such as soil color, moisture, compaction, amount of vegetation cover, ambient temperature, and amount of sunlight available [30].…”

The Impact of Phosphate Solubilizing Bacteria Modified Biochar on Maize Seedling Growth and Rhizosphere Phosphate Availability

“…In recent years, biochar, an emerging material that serves as a fertilizer, adsorbent, soil improver, and heavy metal chelating agent, has increasingly been reported to improve the structure of the soil microbiome and serve as a carrier of microbial fertilizer [14][15][16][17][18]. Studies have shown that the unique physical and chemical properties of biochar can provide a place for the growth and reproduction of phosphate solubilizing bacteria and promote their phosphate solubilizing activity [19].…”
