“…A large proportion of storage materials accumulated in mazzard cherry seeds (45%) are lipids (Kamel and Kakuda, 1992) in the form of triglycerides (Bernardo-Gil et al, 2001). Seeds of Cuphea carthagenesis [a mazzard herb found in Mexico and Central and South America (Graham, 1988)], classified as suborthodox (intermediate), contain large amounts of storage lipids, very much like mazzard cherry seeds, and they lose the ability to germinate during storage at 5 • C at high w.c. levels (< 5%) (Crane et al, 2006).…”

Abstract• The sensitivity of dormant seeds of mazzard cherry (Prunus avium L.) of Polish provenances to extreme desiccation and/or the ultra-low temperature of liquid nitrogen, LN (−196 • C), was investigated to identify the optimum seed water content (w.c.) at this temperature.• Germination and seedling emergence tests in this study showed that there is no critical seed w.c. for deeply desiccated seeds (stone w.c. 1.6%), although such desiccated seeds were sensitive to the temperature of LN in the seedling emergence test. For seeds frozen in LN, the highest germinability was observed at w.c. of 9.0-16.9%, but seedling emergence was then significantly lower than in nonfrozen seeds. The 2-year of storage in LN of seeds desiccated to 7.8% w.c. did not decrease germinability after thawing, in comparison with 2-year of storage at −3 • C. Storage in LN showed that if seeds were stored after breaking of their dormancy, germinability after storage was lower because of the necessity of seed desiccation to the lower level (∼ 8%) of w.c. after stratification (before storage). Secondary dormancy was induced in seeds desiccated after stratification.• The results of this study demonstrate the potential for long-term cryopreservation of mazzard cherry seeds in forest gene banks.

Pour les semences congelées dans LN, la plus forte capacité de germination a été observée à une teneur en eau de 9, 0−16, 9 %, mais l'émergence des semis a ensuite été beaucoup plus faible que dans les semences non congelées. Deux ans de stockage LN pour les semences déshydraté à une teneur en eau de 7,8 % n'a pas diminué la capacité de germination après décongélation, en comparaison avec 2 ans de stockage à 3 • C. Le stockage en LN a montré que si les semences ont été stockées après la levée de leur dormance, leur capacité de germination après stockage a été plus faible en raison de la nécessité d'une dessiccation à un faible teneur en eau (∼ 8%) après stratification (avant stockage). Une dormance secondaire a été induite chez des semences déshydratées après stratification.• Les résultats de cette étude démontrent le potentiel, pour une cryopréservation à long terme, des semences de merisier dans des banques forestières de gènes.

“…Also oil rich seeds such as European hazelnut (Corylus avellana) are considered orthodox species that tolerate storage in LN at lower levels of MC 7.2-9.1% (WC 0.08-0.10 g·g -1 ) [31]. Higher seedling emergence after LN treatment from seeds with high MC may be connected with their high lipids content [26,46]. Similar results showing a higher seed tolerance for LN at higher MC was also observed for oil rich seeds considered as intermediate i.e.…”

“…The difference between germinability and seedling emergence results from seed vigor which can be affected by multiple factors. For instance, P. avium seeds are rich in unsaturated fatty acids [26]. It was previously shown that seeds with high lipid content (Fagus sylvatica L.) are more sensitive to oxidative stress [42].…”

A new insight in desiccation tolerance and cryopreservation of mazzard cherry (Prunus avium L.) seeds

2015

A variable response of Prunus avium L. seeds to desiccation and storage in liquid nitrogen (LN) has been reported in the literature. The majority of these experiments were conducted on initially dried seeds. The desiccation and LN exposure tolerance of fresh P. avium seeds is unknown. In the present study, fresh seeds were used to determine seed response to desiccation and cryopreservation. Desiccation of seeds from a moisture content (MC) of 19.7-20.2% to 10.1-10.9% or 07.6-8.5% reduced seedling emergence from approximately 73 to 19 and 16% for first provenance; and from approximately 89 to 10-12% for second provenance of seeds. After exposure to LN, seeds had the highest seedling emergence when seed MC was the highest (19.7 and 20.2%, respectively) prior to cryostorage. Results indicated that P. avium seeds should be classified as intermediate. For cryopreservation in seed banks, we recommend that seeds be dried directly after extraction from fruits in the range of 16.8-20.2% of MC (0.21-0.25 g·g

“…RSM is a faster and more economical method for collecting research results than classic one-variable-at-a-time or full-factors experimentation. RSM has been successfully employed to model and optimize supercritical CO 2 extraction of oils from cherry seed [20], walnut [21], apricot kernel [22], hazelnut [23], rosemary [24], and rosehip seed [25].…”

Response Surface Optimization of Essential Oil and Diosgenin Extraction from Tribulus terrestris via Supercritical Fluid Technology

2011

Four operating parameters of supercritical carbon dioxide extraction were optimized by the response surface method. The central composite rotatable design was used to maximize extraction recovery of essential oil (specifically diosgenin) from Tribulus terrestris. The obtained data were adequately fitted into two second-order polynomial models for essential oil and diosgenin. The linear terms of pressure, temperature, and extraction dynamic time, the quadratics of pressure and extraction dynamic time, and the interactions of the following two variables: (i) pressure and temperature, (ii) pressure and extraction dynamic time, and (iii) temperature and extraction dynamic time had significant effects on diosgenin recovery.
