To ensure the germination capability and viability of native tree species it is important to know the optimum conditions for seed storage in the long term. In response to this, we investigated the effect of seed storage on the germination, viability, and velocity of germination (VG) of Vallea stipularis, Hedyosmum luteynii and Oreopanax avicenniifolius. The seeds were collected in Llaviucu and Mazan forests in Cajas National Park and exposed to different treatments of seed storage : three levels of seed moisture content (initial, medium and low), two levels of temperature (10oC and room temperature) and three periods of storage (3, 6, and 12 months). The research revealed that seeds of V. stipularis stored at 10oC for 12 months had the lowest germination values, even null percentages ; the more the seed viability and VG decreased when the time of seed storage increased. The seeds of H. luteynii showed high germination and viability up to 12 months of storage at 10oC, however, its germination was later and little synchronized. The room temperature did not work well for germination and VG for both these species, although, H. luteynii maintained its viability intact up to the last period of evaluation. O. avicenniifolius maintained at 10oC and room temperature its germination capacity up to 12 months but with a lower percentage. The knowledge generated contributions to better seed management in ex situ conservation programs and plant propagation for restoration.

لضمان قدرة الإنبات وقدرة أنواع الأشجار المحلية على البقاء، من المهم معرفة الظروف المثلى لتخزين البذور على المدى الطويل. وردا على ذلك، قمنا بالتحقيق في تأثير تخزين البذور على الإنبات، وقابلية البقاء، وسرعة الإنبات (VG) من Vallea stipularis، Hedyosmum luteynii و Oreopanax avicenniifolius. تم جمع البذور في غابات Llaviucu و Mazan في حديقة Cajas الوطنية وتعرضت لمعالجات مختلفة لتخزين البذور: ثلاثة مستويات من محتوى رطوبة البذور (الأولي والمتوسط والمنخفض)، ومستويين من درجة الحرارة (10 درجة مئوية ودرجة حرارة الغرفة) وثلاث فترات تخزين (3 و 6 و 12 شهرًا). كشف البحث أن بذور V. stipularis المخزنة عند 10 درجات مئوية لمدة 12 شهرًا كانت لها أدنى قيم الإنبات، حتى النسب المئوية الفارغة ؛ كلما انخفضت صلاحية البذور و VG عندما زاد وقت تخزين البذور. أظهرت بذور H. luteynii إنباتًا وقابلية بقاء عالية تصل إلى 12 شهرًا من التخزين عند 10 درجات مئوية، ومع ذلك، تم إنباتها لاحقًا وقليلًا ما تمت مزامنتها. لم تعمل درجة حرارة الغرفة بشكل جيد للإنبات و VG لكل من هذين النوعين، على الرغم من أن H. luteynii حافظت على بقائها سليمة حتى الفترة الأخيرة من التقييم. O. avicenniifolius حافظت على درجة حرارة 10 درجة مئوية ودرجة حرارة الغرفة وقدرتها على الإنبات حتى 12 شهرًا ولكن بنسبة مئوية أقل. تساهم المعرفة المتولدة في تحسين إدارة البذور في برامج الحفظ خارج الموقع وتكاثر النباتات من أجل الاستعادة.
