“…The differences in character could be caused by genetic and environmental factors between accessions planted in Purwodadi (Indonesia) and Ghana. Plants that grow in different geographical areas have different characteristics due to somatic mutations which can show variations in the morphology and appearance of these plants, including the D. alata [21,22].…”

Dioscorea spp. (Yam) is an edible tuber plant from the Dioscoreaceae family. There are around 600 species of Dioscorea spp., one of them is Dioscorea alata. D. alata has a wide range of morphological characteristics, including shape, size, skin color, flesh, and tuber texture. This research focused on D. alata with purple tuber flesh. This study aims to reveal the diversity of D. alata in Purwodadi Botanical Garden based on its morphological characteristics. Characterization is an important aspect of identifying D. alata diversity. Characterization was performed on six D. alata accessions from the Purwodadi Botanical Garden, DA 28, DA 36, DA 57, DA 86, DA-SB, and DA-Tr. Morphological characterization can be divided into qualitative and quantitative stem and leaf properties. The morphological feature data were processed using NTSys 2.11a software. The observation results showed that D. alata from different accessions had diverse morphological characteristics such as stem color, wing color, leaf margin color, leaf vein color, petiole color, and petiole wings color. The dendrogram results showed that DA 36 and DA SB accessions had a very close level of similarity. Meanwhile, the DA-Tr accession exhibited the most distinct character from the other accessions with the dominant color being purple covering stems, stem wings, leaf veins, leaf margins, petioles, and petiole wings.

“…The apical meristem, a tissue that supports plant height growth, generates new cells at the root or stem tip, resulting in increased plant height and length. This is because mycorrhiza-forming fungi can generate plant hormones like auxins, cytokinins, and gibberellins and vitamins that accelerate plant tissue growth [12]. Shade density is linked to the intensity, quality, and duration of light radiation that plants receive to carry out photosynthesis, and it has a prominent impact on natural sapling height [12].…”

Shade density is linked to the intensity, quality, and duration of light radiation that plants receive to carry out photosynthesis, and it has a prominent impact on natural sapling height [12]. Light intensity is also correlated with temperature and humidity; an increase in light intensity will elevate temperature and reduce relative humidity, thereby influencing the evaporation rate [13].…”

The obstacles to the propagation of Shorea platyclados involve the uncertain flowering and fruiting seasons, the recalcitrant nature of the seeds, and the dependence on shade for growth. Furthermore, a mutualistic symbiosis, called mycorrhizae, usually exists between the roots and fungi, similar to other species of Dipterocarpaceae. This consequently hinders the regeneration process, which in turn may threaten the sustainability of this species in the wild. Ex-situ conservation using wildings is one of the measures that can be taken to overcome this issue. This study aimed to assess the initial growth of S. platyclados seedlings by administering different amountsof mycorrhizal biofertilizers under varying shade conditions at four and eight weeks of age in the nursery. A randomised complete block design was employed with the dose of biofertilizer as the treatment (0, 2.5, 5, 7 and 9 g/polybag) and shade as the group (0, 50, 60 and 70%). Observations were taken in the nursery at four and eight weeks of age. The observation parameters included the survival percentage, height growth, diameter growth, and vigour of the seedlings. There were significant differences in percentage of survival. Still, significant differences in height growth were observed with different doses of biofertilizer and shading at both four and eight weeks of age. Significant differences in diameter growth were observed with different doses of biofertilizer at both four and eight weeks of age, but not with different shades. No significant differences were observed for seedling vigour with different doses of biofertilizer and shade at both four and eight weeks of age. The optimal amount of biofertilizer was 5 g/polybag, resulting in maximum growth. This was achieved in a shade of 60%.
