“…Other species such cherimoya (Annona cherimola) have been also maintained in vitro during 250 subcultures (more than 20 years) in our laboratory, maintaining the shoot multiplication rate but loosing most of the rooting capabilities (Encina, unpublished results). To date, we do not found even in the last reviews (Al-Shara et al 2018; Costa et al 2019) any references involving long-term cultures focused to proliferation and preservation of papaya in vitro during long periods of time.…”

We present the data on proliferation corresponding to 10 years of continuous incubation in vitro of papaya shoots, and propose a reliable method for long-term micropropagation for papaya, using two types of explants: Microshoots from somatic embryos, and from axillary buds of papaya. Three different media were assayed. The proliferation medium (PPRM) allowed to maintain papaya shoots under continuous proliferation during 20 years, maintaining a consistent behaviour. Most of the shoots developed in PPRM rooted during the incubation, and after acclimated easily, maintaining the morphological characteristics of the parental plants, flowering and setting fruits normally. The PPRM medium consist in MS medium supplemented with NAA (0.1 mg l-1), BA (0.5 mg l-1), GA3 (0.5 mg l-1) and Adenine sulphate (40 mg l-1). The average multiplication rate was higher than 20 shoots per explant along the long-term assay. The elongation medium (PELM), was designed to recover shoots with a poor growth, and allowed the development of high quality shoots ready for rooting, and consist in a MS basal medium supplemented with NAA (0.1 mg l-1), Kin (0.5 mg l-1) and GA3 (1 mg l-1). The rooting medium (PROM) was designed to induce high quality roots from non-rooted shoots and consist in a half strength MS medium plus IBA (1mg l-1). On PROM, agar can be exchanged for expanded vermiculite. Acclimation took place inside an acclimatization tunnel under progressive hydric stress. After 4 weeks, the plant recovery rate was 90% for plants maintained under continuous proliferation during ten years.

In this article, we present proliferation data from 10 years of the continuous in vitro incubation of cv. Solo papaya shoots and propose a reliable method for the long-term micropropagation of papaya, using microshoots developed from the axillary buds of papaya shoots as primary explants. Three different media were assayed. The proliferation medium (PPRM) allowed us to maintain papaya shoots under continuous proliferation for 20 years, maintaining consistent behavior. Most of the shoots developed in the PPRM rooted during the incubation and then acclimated easily, maintaining the ploidy and morphological characteristics of the parental plants, and flowering and setting fruits normally. The PPRM medium consisted of MS medium supplemented with naphthalene acetic acid (NAA) (0.1 mg L−1), benzyladenine (BA) (0.5 mg L−1), gibberellic acid (GA3) (0.5 mg L−1), and adenine hemisulphate (40 mg L−1). The average multiplication rate was higher than 20 shoots per explant during the long-term assay. The elongation medium (PELM) was designed to recover shoots with poor growth and allowed the development of high-quality shoots ready for rooting. It consisted of an MS basal medium supplemented with NAA (0.1 mg L−1), kinetin (KIN) (0.5 mg L−1), and GA3 (1 mg L−1). The rooting medium (PROM) was designed to induce high-quality roots from nonrooted shoots and consisted of a half-strength MS medium and indole-3-butiryc acid (IBA) (1 mg L−1). On PROM, agar can be exchanged for expanded vermiculite. Acclimation took place inside an acclimatization tunnel under progressive hydric stress. After 4 weeks, the plant recovery rate was 90% for plants maintained under continuous proliferation for ten years. The main objective of this work was to provide a micropropagation method which would maintain healthy elite genotypes of papaya for long periods of time and produce a high number of good quality plants.

“…O sucesso da fruticultura depende de diversos fatores, e dentre eles, um dos mais importantes está na implantação da cultura, sobretudo a etapa de produção de mudas, atrelado principalmente a qualidade fitotécnica e fitossanitária (Silva et al, 2010). A obtenção de mudas de qualidade garante além de maior uniformidade do pomar, segurança em relação a contaminação por pragas e doenças, o que permite maiores probabilidades de sucesso do produtor rural (Faleiro et al, 2018;Costa et al, 2019).…”

RESUMOO substrato deve ser escolhido para proporcionar condições adequadas para a germinação e o desenvolvimento de plantas, garantindo o sucesso do empreendimento. Assim, objetivou-se estudar cinco substratos para germinação e produção de mudas de maracujá e mamão formosa. No experimento foram utilizados cinco tratamentos: S1; S2; S3; S4 e S5, variando entre substratos comerciais e inertes. Foram avaliados: porcentagem de emergência (E), índice de velocidade de emergência (IVE); tempo médio de emergência (TME), velocidade de emergência (V), altura de plantas aos 15 (Alt15) e 30 dias (Alt30), massa seca da parte aérea (MSPA), raiz (MSR) e total (MST), razão MSPA/MSR, comprimento da raiz (CR), diâmetro do caule (DM) e o índice de qualidade de Dickson (IQD).
