“…Similar results to those reported by Souza et al (2016) in the cryopreservation of Physalis peruviana seeds with up to 11% water content, whereby it was also observed that-after 12 months of storing in LN-that around 90% of the preserved diaspores showed normal germination process, resulting in healthy seedlings suitable for development in a nursery.…”

Piper aduncum and Piper hispidinervum are species found primarily in the Amazon region, and have been highlighted by the fact that they contain, in their essential oils, significant amounts of dillapiol and safrole. The aim of this work was to assess the seed behavior of P. aduncum and P. hispidinervum and to develop strategies for medium-to long-term storage of the species at sub-zero and cryogenic temperatures. In the first experiment, seeds were desiccated and their water content was determined. Then, the seeds were kept at −20°C for up to 90 days. In the second experiment, seeds were stored for up to 24 h in liquid nitrogen (LN; −196°C), with and without the use of cryoprotectants. Finally, for assessing the efficiency of these techniques, seeds were stored at −20°C and in LN for up to 360 days. The germination rate was more than 90% for both species when stored at −20°C or LN, without compromising their viability and development. The results suggest that P. aduncum and P. hispidinervum have seeds with orthodox behavior, which can be stored for the medium to long term at sub-zero and cryogenic temperatures without the need for use of cryoprotectants.

“…2). These findings are apparently contrary to the general rules of storage, which predict that water contents higher than 13% are undesirable (Labbé, 2003) and that maintaining low water contents in orthodox seeds may increase the germination percentage and seed vigour (Souza et al, 2016). Similar results were recently reported for Calamus shendurunii (Jacob et al, 2016), whose seeds had 35% initial water content and 97% germination.…”

The present study aimed to evaluate the possibility of using cryopreservation method for conservation of cajuzinho-do-cerrado achene (Anacardium humile). To accomplish this aim, the physiological quality of cryopreserved achenes was compared with the quality of samples stored under other conditions. The quality of cryopreserved achenes with different water contents was also evaluated to establish a water-content limit for seed-viability maintenance. Achenes with physiological maturity were stored in liquid nitrogen at -196 °C with the following water contents: 28 (initial content) 14, 12, 8 and 5% moisture content (m c ). Subsequently, the achenes were subjected to 3 thawing methods: slow/gradual, fast and microwave thawing. Achenes were also subjected to different six conservation methods: cryopreservation in liquid nitrogen (LN) at -196 °C, cryopreservation using 10% cryoprotectants (Dimethyl sulfoxide (DMSO) or Glycerol), 10 °C biochemical oxygen demand (BOD) incubator, -80 °C ultra-low freezer and room temperature (25 °C ±3), with testing after storage in these environments for 5 and 10 months. The treatment effect on achene, physiological quality was assessed by seed germination (percentage) and vigour (germination speed index, electrical conductivity and root and shoot length). The results showed that reduction in the water content considerably reduced the germinating potential of Anacardium humile achenes for cryopreservation. Conversely, the thawing methods had no effect on the physiological quality of cryopreserved achenes; thereby, allowing the choice of the most practical thawing method (microwave). We also concluded that cryopreservation in liquid nitrogen may be used as a viable alternative for conservation of Anacardium humile achene.

Physalis peruviana é uma planta herbácea, arbustiva e perene, pertence à família Solanaceae. Os seus frutos apresentam alto valor nutricional e propriedades medicinais. Com a crescente importância e sua propagação ser sexuada, buscam-se sementes de alta qualidade. A fase inicial do desenvolvimento de plântulas é delicada e de grande importância; em campo, estão sujeitas a diversos fatores que podem interferir no seu desenvolvimento, como o estresse hídrico. Com isso, objetivou-se avaliar o efeito do estresse hídrico na qualidade fisiológica de sementes de P. peruviana. As sementes foram submetidas ao teste de envelhecimento acelerado conduzido a 41 °C e 100% UR por 0; 48; 72 e 96h para obtenção de diferentes lotes. O estresse hídrico foi induzido com PEG-6000 com quatro potenciais osmótico, 0,0 (controle); -0,2; -0,4 e -0,6 MPa. Avaliou-se a germinação e o vigor das sementes (primeira contagem, comprimento da parte aérea e da raiz). O envelhecimento acelerado reduziu a porcentagem de germinação à medida que aumentou o tempo de exposição. Conclui-se que os lotes de sementes de P. peruviana de maior qualidade fisiológica apesentaram melhor desempenho sob estresse hídrico induzido por PEG 6000 até o potencial -0,2 MPa. A restrição hídrica provocou um menor crescimento de plântulas da parte área, no entanto, quando as sementes foram submetidas ao potencial -0,2 MPa, verificou-se um aumento no comprimento radicular.
