“…Although progress has been made, the causes of seed deterioration is still not well elucidated. In addition, seed aging is often studied by using various accelerated aging tests (Bijanzadeh et al 2016, Hussein et al, 2011Prochazkova and Bezdeckova, 2009;Vijay et al, 2015;Barreto & Garcia, 2017). Few studies have been made on natural long-term aging of seed.…”

Highlights• Moringa seed with MC ≤ 5% can be kept at constant temperature ≤ 30 °C beyond 12 months.• Moringa seed may continue synthesizing antioxidant during postharvest storage.• Storage period the main factor influencing change in polyphenol content and antioxidant capacity.• Packaging type and storage temperature influence flavonoid and lipid peroxidation.• Increase in lipid peroxidation and flavonoids correlate with the loss of viability. AbstractThere have been increased interest to propagate Moringa oleifera because of its multipurpose uses.However there are still no appropriate guidelines for long-term storage of Moringa seed because diverse results are reported in literature. Although progress has been made to understand the causes of seed deterioration, few studies have been made on natural long-term aging of seed. This study aimed to determine and compare the level of polyphenols, flavonoids, MDA and antioxidant 2 capacity in Moringa seed stored in paper and aluminum bags at -19°, 4°, 20° and 30˚C for 24 months as well as to investigated the relationship between these secondary compounds and Moringa seed viability. Seeds were evaluated in regular intervals of 6 months. There was minor difference between viability percentage of seed stored below 20˚C. Significant decline in viability was recorded in seed stored for 24 months in aluminium bags at 30˚C as a result of high moisture content (8%) and high temperature at which seed were exposed; While Seed stored at 30˚C in paper bags had low moisture content (5%) and retain a high viability percentage . Storage duration was the main factor affecting the changes on polyphenols and antioxidant activity levels. Although storage duration played a major role on the change in flavonoid and MDA content, the influence of storage temperature and the seed moisture content was also evident on some treatments. The change in investigated secondary compounds in seed did not always reflect on its viability percentage, but two relationships emerge from this study: The lowest moisture content, slow increase in MDA content, the lowest flavonoids content and the highest germination % in seed stored in paper bags at 20 and 30°C at 24 months; and the highest MDA content, highest increase in flavonoids and lowest viability percentage observed in seed stored in aluminium bags at 30°C for 24 months. It is recommended that for long-term storage (≥12 months) Moringa seed be stored with low moisture content (≤5%) at constant temperature below 30°C.

“…Shoot length of emerged seedlings of the seeds stored at Gannoruwa and Kundasale showed same behavior and the lowest was observed in Mahailuppallama. Vijay et al, (2015) also concluded that seed deterioration depends on chemical composition and storage environment by studying hybrid sunflower-RSFH-130 (Helianthus annuus). Means with the same superscript letters within rows are statistically non-significant at 5% level of probability (DMR test).…”

Bean is a popular vegetable grown in most parts of Sri Lanka. Farmers and home gardeners purchase seeds in packeted form retail outlets. However, quality problems are frequently reported, especially on low field germination. Quality parameters namely, percentage germination, field emergence, seedling length, vigour index and chlorophyll fluorescence analysis were used to determine the effect of different storage environmental conditions on seed longevity of two bean varieties during a two-year storage period, 2016 to 2018. Seeds in triple-laminated packets stored in four contrasting conditions; low temperature storage conditions (Tem. 5oC, 65% RH); three geo-environmental conditions namely, Gannoruwa (mid country wet zone), Kundasale (mid country intermediate zone), and Mahailuppallama (low country dry zone) showed varied behavior in seed quality parameters respective of the variety. It was apparent that germination test alone does not represent the full potential of field emergence. Results of the present study revealed that when field emergence and vigour are also taken in to account, both varieties of bean seeds can be stored under ambient conditions at Gannoruwa, Kundasale or MahaIlluppallama for a maximum period of 12 months, without compromising the seed quality. The seeds stored under low temperature conditions (i.e. 5 °C), maintained the seed germination over 75% for a period of 24 months.

“…Storage may be an excellent alternative to avoid the shortage of seeds, aiming at maintaining or minimizing the loss of physiological quality until sowing [4]. However, seeds tend to undergo physiological and biochemical changes, as a consequence of storage conditions, with negative consequences in their quality conservation [5].…”

Seeds vigor defined in the laboratory does not always reflect the final quality of seedlings produced under nursery conditions or even their survival in plantations. So, we studied the influence of Cedrela fissilis seed storage conditions on its emergence and the morphological quality of produced seedlings. Seeds were collected in October/2011, benefited, conditioned in closed glasses, and stored in three environments for a period of 515 days. Treatments consisted of: I - seedlings produced from seeds without storage (control); II - seedlings produced from seeds stored in a dry chamber; III - seedlings produced from seeds stored in a humid chamber; IV - Seedlings produced from seeds stored in an uncontrolled environment (laboratory). Sowing was performed in 50 cm³ plastic tubes filled with decomposed pinus bark and coconut fiber (50/50 v/v) and packed in a glasshouse. The study analyzed the percentage of seedlings emergence, mean seedlings emergence time, stem diameter, total height, the ratio between total height and stem diameter, shoot length, root length, total, root and shoot dry biomass, and Dickson quality index. Seed storage proved to be a negative factor for the emergence and vigor of C. fissilis seedlings, regardless of the storage environment. In addition, seeds vigor is a preponderant factor to increase seedlings' morphological quality, such as stem diameter and height.
