Seedling Parameters of Soybean Cultivars as Influenced With Seed Storage Periods, Conditions and Materials

Abstract

This investigation was elucidated seedling characters effects of soybean cultivars i.e. Crawford, Giza 111, Giza 21, Giza 22 and Giza 35 due to ageing (storage) in different packaging material i.e. seeds or pods in plastic or cloth bags for different periods i.e. 3, 6, 9 and 12 months under ambient and refrigerator conditions. Seedling parameters i.e. root and shoot length, seedling fresh and dry weight root/shoot ratio and seedling vigor index were decreased with the period of ageing. Soybean cultivars are stored in plastic bags were affected due to storage but the effects were more pronounced in the plastic bags as compared to cloth bags. It could be stated that Giza 111 exceeded the other cultivars in root length, shoot length and seedling vigor index. Giza 22 and Giza 21 cultivars exceeded the other cultivars in root/ shoot ratio. Giza 35 exceeded other cultivars in seedling dry and fresh weight. Storage under refrigerator conditions at 10 ºC ± 1 exceeded storage under ambient conditions in root length, shoot length, root/shoot ratio and seedling fresh and dry weight and seedling vigor index. Results clearly showed that root and shoot length, root/shoot ratio, seedling fresh and dry weight and seedling vigor index significantly affected by the varies interactions.

Effect of Natural Seed Aging on Root and Shoot Traits in Bread Wheat (Triticum aestivum L.) Cultivars

“…Root length of control groups mostly existed in a range of 18-22.7 cm, while in long-term storage most of the cultivars in terms of root length were accumulated. A similar result was also reported a decline in root length of maize with increasing aging duration (Kandil et al, 2013).…”

“…In the present study, Alpaslan and Zencirci 2002 were ranked low and high for shoot mass in both long-term storage and control, respectively. A close look at the data in Table 2 suggested that average shoot mass was declined by long-term storage with 0.14 g compared to control with 0.17 g. The results were confirmed by results of Kandil et al (2013) that indicated a decline in root length, shoot length, and shoot mass through long-term storage in soybean.…”

Effect of Storage Periods on Physical Quality and Seed Vigor of Four Varieties of Sorghum (Sorghum Bicolor [L.] Moench)

“…Root length and dry weight difference may be due to genetic differences and biochemical composition of each variety causing differences in deterioration rate and decreased vigor (Kandil et al, 2013). High dry weights showed that the use of reserves in the seed is very efficient because the seeds that have a high vigor can transmit raw materials to the embryo shaft quickly so that the accumulation of dry weight increases.…”

“…dry weight of normal seedlings, the speed of germination and total normal seedlings decrease could be seen in Figure 2. Kandil et al (2013) reported that root length, shoot length and dry weight of normal seedling decreased after being stored for 12 months when compared to the 3,6, and 9 months stored period of soybean seeds Increased storage period on seed wheat from storage of 3,6 and 9 months significantly affect the viability and quality of seeds, the germination percentage was lowest in 9 months.…”

“…Primary Root Length of Normal Seedling was obtained by measuring the length of primary root from the base to the tip of the root as follow as described by Kandil et al (2013) and AOSA (2010).…”
