Variations of Leaf and Storage Roots Morphology in Ipomoea Batatas L. (Sweet Potato) Cultivars

Abstract

Ipomoea batatas L. is one of the main crops in the world and is planted mainly for its tuber. This vegetative plant is hard to distinguish between their wide varieties during the harvesting period. We sought a general comparison of variations across different varieties of sweet potato leaves. A total of 6 different local varieties of sweet potato leaves were characterised for leaf width, length, thickness, area, shape, arrangement, margin, venation and the colour index (in L*a*/b*). The morphological characteristics of the storage roots were also found to be different for the different varieties. Hence, the leaf morphology can be used to distinguish the different varieties of sweet potato plant in Malaysia.

A review of therapeutic potentials of sweet potato: Pharmacological activities and influence of the cultivar

“…[12]. [18]. In Southern Africa, formal sweet potato breeding was initiated in 1952 [19] and the most commercially successful has been Blesbok, a purple-skinned high yielding cultivar with low dry matter content [20].…”

Effects of different drying methods on the proximate composition and antioxidant activities of Ocimum basilicum leaves

“…According to Kumar and Pandey (2013) pyrone structure are widely present in plants. High antioxidant activity in green leafy vegetables is partially due to the presence of flavonoids (Hue et al, 2012). The consumption of flavonol, that is, quercetin, which is rich in onions and/or apples, reduces the risk of prostate, lung, stomach, and breast cancer (Kumar and Pandey, 2013).…”

Assessing the remarkable morphological diversity and transcriptomic basis of leaf shape inIpomoea batatas(sweetpotato)

“…Ipomoea batatas, the sweetpotato, is an important staple root crop worldwide (Khoury et 111 al., 2015), as it produces the highest amount of edible energy per hectare (Khoury et al, 2015) 112 and also provides an important source of nutrients in the form of vitamin A, calcium, and iron 113 (Kays & Kays, 1998). Sweetpotato displays striking morphological variation in leaf shape across 114 its ~6000 documented varieties (Huaman, 1987), but very few studies have examined the 115 extensive leaf shape diversity in this species (Huaman, 1987;Hue et al, 2012;Rosero et al, 116 2019). Studies that have examined leaf shape phenotypes in sweetpotato are limited to a few 117 cultivars and/or present traditional measures of leaf shape traits.…”
