Morphology and fruit quality characters of Pineapple (Ananas comosus L. Merr) cv. Queen on three sites planting: freshwater peat, brackish peat and alluvial soil

Abstract

The growth and fruit quality of the crop is strongly influenced by the environment in which it grows. The purpose of this study was to observe the growth and fruit quality of pineapple (Ananas comusus L. Merr) cv. Queen that cultivated in the three different ecosystems. Pineapple cv. Queen was planted in three different ecosystems, namely in freshwater peatlands, brackish water peatlands and Alluvial soils in Riau province. Morphology and fruit quality characters of pineapple were evaluated at each ecosystem. The result of this study displayed that pineapple cultivated in freshwater peatland having fruit weight (1540.64 g), fruit length (19.80 cm), sucker number (4.94 pieces), slip number (3.16 pieces), total dissolve content (14.19°Brix), titratable acidity (TA) (0.51%), and water content (85.94%) higher than others site. Morphology and fruit quality characters of pineapple that cultivated in brackish water peatlands and alluvial soils were not significantly different. Our finding of this study that pineapple grows well on three soil types and is adaptive in peatland so that pineapple can be selected as an alternative crop to be developed in the peatland in the future.

Effect of Planting Density on the Agronomic Performance and Fruit Quality of Three Pineapple Cultivars (Ananas comosus L. Merr.)

“…Regarding fruit length, the results obtained are close to the values reported in other studies [12,30]. In contrast, the diameter of fruits harvested in this study exceeds that reported for fruits of pineapple "Queen" cultivar, whose values were less than 10 cm [13].…”

“…Nevertheless, the technical level of agricultural practices can significantly influence the expression of the crop's genetic potential [7,12]. e records of the morphological characteristics of the pineapple plants reported in this study are lower than the values reached by "Queen" cultivar cultivated in three different ecosystems (freshwater peat, brackish peat, and alluvial soil), as they reached a height greater than 80 cm and D-leaf lengths over 65 cm [13]. e quantification of these morphological characteristics (including the number of leaves) is of great importance in pineapple cultivation because they are related to photosynthetic efficiency and fruit development [12][13][14].…”

“…TSSC ( 0 Brix) indicates the level of sweetness of the fruit, which is influenced by the TDA in fruit. Sweet taste is determined by TSSC/TDA; the higher the TSSC/TDA ratio, the sweeter the taste of the fruit (Rosmaina et al 2019). The highest edible part (%) was obtained from the Kuansing population, reaching 34%, which was not significantly different from the Gunung Sahilan population (32.60%) and Kuok population (32.18%), followed by the Kampar Kiri population (29.10%).…”

“…In addition, the accumulation of organic matter in peat soil can affect the sweetness level of the fruit. Characterization of other horticultural crops was reported by Rosmaina (2019) that pineapple plants grown on peat soil had higher fruit weight and pineapple fruit length than pineapples grown on mineral soils. This result might be due to the availability and uptake of nutrients in peat soils, which are higher than in mineral soils.…”

“…This method is easy and quick because it can be observed directly, although the morphological characters could be influenced by the environment, plant age, season, and growth phase (Rosmaina et al 2021;Zulfahmi et al 2013). The use of morphological characteristics for plant identification and characterization has been widely reported, including in pineapples (Adje et al 2019;Hadiati et al 2009;Rodriguez et al 2020;Rosmaina et al 2019Rosmaina et al , 2021, mangosteen (Mansyah 2012;Sulassih 2011), N. lappaceum (Barreto et al 2015;Kuswandi et al 2014;Muhamed et al 2019;Salman 2015;Windarsih 2019), pasak bumi (Eurycoma apiculata) (Zulfahmi et al 2020), and chili plants (Rosmaina et al 2016). This study aims to characterize the morphology and quality of N. ramboutanake fruit, and to investigate the taxonomical kinship among the N. ramboutan-ake population in Riau Province based on such characters.…”
