“…These trends confirm the strategic importance of the species for both agriculture and food security, and industrial uses [2]. Onion is a cold season, biennial crop bearing an edible bulb, whose propagation usually occurs by seed to better support the strong increase in the growing area, especially in small-farmer agriculture, despite other vegetative strategies being available [3][4][5][6]. The harvest of the crop for bulb production eliminates the chances of producing the seed, so Horticulturae 2022, 8, 781 2 of 17 that dedicated crop from the bulb is used for the seed production.…”

(1) Background: the production of onion seeds is limited by the competition between seeds and the vegetative organs and by scape lodging. However, information on the effects of plant growth regulation on onion seed production is scarce. Aim of the present study was to evaluate the seed yield components and germination ability of onion seeds as affected by the timing and dose of an ethylene application, a plant growth regulator able to modulate shoot–flower competition; and chitosan, an elicitor of plant defense mechanisms able to increase its tolerance to various stresses. (2) Methods: Onion was treated with ethylene at the recommended dose (100% RD) of a commercial product, at 150% RD in two contrasting phenological phases or untreated (control), or ‘with’ or ‘without’ chitosan, and the seed yield components and germination trend were measured. (3) Results: 100% RD at an early phase of growth did not influence the seed yield and increased the thousand seed weight (TSW) by 3.2%. The application of 150% RD decreased the seed yield by 33.5%, and this occurred irrespective of the timing of application. Such decreases were due to a reduction in the number of seeds per flower. The application of chitosan did not affect the crop at 100% RD and increased the seed yield and slightly increased, but not significantly, the TSW under 150% RD. Germination of the fresh seed was 92%, and 17 months of aging reduced it by 14%, with no effects of the treatments on the germination pattern. (4) Conclusions: the ethylene application mostly affected TSW but not the yield, whereas high doses of ethylene reduced yields irrespective of the timing of application. Such a result may have been due to a delay in the flowering onset that occurred in a relatively dry month. Chitosan sustained its yield when the yield potential was reduced by 150% RD, and such a result was likely due to physical protection from the transpiration since the synthetic fungicides applied did not likely allow the pathogens to infections. These results have implications for establishing the timing and dose of application of plant growth regulators and elicitors in seed onions to sustain the seed quality.

Metode pembibitan nanas yang dapat dikembangkan untuk meningkatkan jumlah bibit yangdapat dihasilkan adalah setek basal daun mahkota. Tingkat kematangan buah diduga berpengaruhterhadap tingkat keberhasilan setek basal daun. Penelitian ini bertujuan untuk mendapatkan informasimengenai pengaruh tingkat kematangan buah pada saat pengambilan bahan setek untuk produksi bibitasal setek basal daun mahkota pada nanas cv. Smooth Cayenne. Percobaan menggunakan RKLT satufaktor, yaitu tingkat kematangan dengan empat taraf perlakuan: tingkat kematangan 1 (K1) : semuamata berwarna hijau; kematangan 2 (K2) : mata buah yang berwarna kuning < 20%; kematangan 3(K3) : mata buah yang berwarna kuning 40-55%; kematangan 4 (K4): mata buah yang berwarnakuning >90%; tetapi yang berwarna jingga kemerahan <20%. Hasil penelitian menunjukkankandungan auksin dan sitokinin endogen tidak berbeda pada semua tingkat kematangan, namunNisbah C/N K3 dan K4 menunjukkan hasil lebih tinggi. Pada semua tingkat kematangan, terbentuknyatunas maksimum terjadi pada 4-6 MST. Tingkat kematangan buah terbaik untuk produksi bibit nanasdengan setek basal daun mahkota adalah K4 (mata buah yang berwarna kuning >90%, tetapi yangberwarna jingga kemerahan <20%). K4 memiliki kecenderunguan menghasilkan setek hidup,bertunas, dan berakar lebih tinggi. K4 menghasilkan bobot kering tunas tertinggi dan memenuhistandar bibit sertifikasi lebih cepat (52 MST).Kata kunci: buah tropis, mata tunas dorman, perbanyakan cepat, split crown

“…Plant propagation involves applying biological principles focused on the multiplication of useful plants of a specific genotype, and there are basically two alternatives of propagation: sexual through seeds or asexual through plant tissues (Megersa, 2017). Asexual propagation is possible due to the totipotency of plant cells, which consists of each cell containing the genetic information and capacity necessary for regenerating all of the parts of a plant and their functions such as generating new stems, roots and leaves (George et al, 2008).…”

“…Methods have been developed for producing plants vegetatively; such as high technology in vitro cultivation (tissue cultivation) or low technology (grafting, cuttings) (Deepak et al, 2016). In rural zones, plants are usually propagated by means of cuttings, for species of interest or for live fences (Costa et al, 2017;Megersa, 2017). The species used for vegetative propagation have growth characteristics and particular requirements of cultivation, from which specific products and benefits are obtained.…”

The tropical dry forest is a diverse ecosystem, but it is poorly protected. In Mesoamerica, this forest is among the most threatened by anthropogenic activities, which makes necessary agricultural practices that incorporate local germplasm preservation. We propose the propagation with stakes of Bursera copallifera, B. fagaroides, and Ipomoea pauciflora, three tree species of the tropical dry forest of Morelos, Mexico. We evaluated if stake survival was related to their diameter, height, and leave's presence for each tree species in a one-year greenhouse experiment. After one year, 79%, 39%, and 9% of the stakes of B. fagaroides, B. copallifera, and I. pauciflora became established, respectively. Only the leaf's presence influences stake survival. The propagation of stakes is a highly viable method for the two Bursera species. With stakes, peasants can develop live fences inside agricultural fields, preserve local germplasm, and simultaneously, the ecological interactions and the ecosystem functions of the species in the landscape. Our work contributes original and transferable knowledge for the vegetative propagation of tree species of the tropical dry forest. This knowledge can help with the conservation of the tropical dry forest and the sustainable management of tree species with ecological and cultural importance.
