“…The morphology and seed mass of M. acuminata var. flava observed in this study are in accordance to previous reports on other varieties and subspecies of M. acuminata (Puteh et al 2011;Vineesh et al 2015;Kallow et al 2020) and also other wild Musa species (Burgos-Hernández et al 2014;Bohra et al 2020). Viability and quality of seeds can be determined by observing their morphological characters.…”

“…Wild banana seeds are generally known to be orthodox or long-term storage under very low moisture and sub-zero temperature. However, several studies have shown that some banana species have intermediate seeds, such as Musa indandamanensis, where the seed viability decreases over time, especially after three months of storage (Bohra et al 2020). Meanwhile Kallow et al (2020) reported that M. balbisiana is considered as orthodox and indicated that M. acuminata subsp.…”

Wild bananas provide important genetic materials for further banana improvement, therefore they need to be conserved and studied. This study aimed to describe morphological characteristics of plant and seed and also to study the seed germination of wild banana M. acuminata var. flava (Ridl.) Nasution. The morphological characteristics were observed descriptively by referring to the descriptor for banana. The internal and external morphology of the seeds were observed using a digital microscope. The germination testing was carried out by a completely randomized design, using fresh seeds extracted from a bunch of fruits with two ripeness levels i.e. fully-ripe (yellow peel) and under-ripe (green-yellow peel). The data resulted was then analyzed using an independent t-test. The results showed that M. acuminata var. flava is characterized as a perennial herb; pseudostem height ≥3 m; male bud like a top with prominent green-yellow bracts; fruit curved and tasted mild-sweet when ripe. The seed is angular with wrinkled surface, and dark brown-black color when ripe. The longitudinal section showed parts of the seeds comprising the seed coat, outer and inner integument, embryo, endosperm, chalazal mass, micropyle cap and channel. The seeds are classified as orthodox, with hypogeal type and gradual germination pattern. The seeds extracted from fully-ripe fruit germinated faster with higher germination percentage and growth variables (root number and plant height). Thus, it is suggested to use physiologically mature seeds (seeds from fully-ripe fruits) which should be separated from the seeds of under-ripe fruits to lower the heterogeneity.

“…In wild banana species-Musa indandamanensis and M. paramjitiana, interaction effect of substrate and chemical treatment have been reported as same pre-treatment showed variable germination in different substrates. [4][5] 1). It also means that though less germination was observed in the sand and VC + soil treatments, the regenerated seedlings had comparable growth and germination percentage was the only factor causing variations in the SVI.…”

Blood fruit is a tropical underutilized species, fruits of which have been identified as source of natural colourant. However, forests are the major source of fruits to native people. In order to conserve the natural population of this species and promote cultivation, nursery techniques need to be standardized. In the present investigation, effect of three substrates viz. vermicompost, sand and soil + vermicompost was studied on seed germination characteristics. Results revealed significant differences among the treatments. Use of vermicompost improved seed germination (69%) significantly over the other substrates used. Though most of the studied seedling growth parameters did not differ among the treatments, significantly highest seedling vigour index (5466.9) was recorded when vermicompost was used as substrate. Considering these findings, use of vermicompost is advisable for germination of blood fruit in nursery.

“…Banana seeds are naturally survived with low water content but have a different dormancy type and experience secondary dormancy as the seeds stored (Kallow et al, 2020). Usually, after months of storage seed viability became reduced and low seedling vigor (Bohra et al, 2020). Some wild bananas have seeds with little endosperm, and some have abnormalities because of the absence and/or deformation of the embryo .…”

Hydropriming Improves Germination and Plant Recovery During Embryo Rescue of Wild Banana Musa acuminata var. tomentosa

Wild bananas are believed to have genes for resistance to biotic and abiotic stress in nature, making them potential genetic resources for creating superior varieties. Wild banana seeds, such as Musa acuminata var. tomentosa are generally difficult to germinate in vivo, so that in vitro embryo culture technique is needed. This study aimed to increase embryo germination and regeneration of wild banana M. acuminata var. tomentosa by soaking the seeds as hydropriming. The treatment comprised of soaking the seeds in sterile distilled water for four periods of time: 0 (control), 1, 4, and 7 days. A total of 45 embryos for each treatment were planted on petri dishes containing MS + 0.5 mg/L BA + 1 mg/L biotin + 1 mg/L proline. The results showed that hydropriming increased the rate of embryo germination and regeneration. Seeds soaked for 1, 4, and 7 days successfully resulted in embryo germination percentages of 87%, 62%, and 62%, respectively, while the control unsoaked seeds germinated with a lower percentage of 42%. One-day soaking treatment was the most optimal treatment to increase the rate of germination and regeneration as well as obtained the best vigor as demonstrated by the highest average height of plantlets, number of leaves, and roots than other treatments. Thus, 1-day seed hydropriming is the best treatment for embryo rescue and regeneration of wild banana M. acuminata var. tomentosa
