Special Issue "Modern Seed Technology"
A special issue of Agriculture (ISSN 2077-0472).
Deadline for manuscript submissions: 30 September 2020.
Interests: seed treatments; coatings; enhancements; biostimulants; seed quality
Satisfying the increasing number of consumer demands for high quality seed with enhanced performance is one of the most imperative challenges of modern agriculture. In this view, it is essential to remember that the seed quality of crops does not improve after harvest. Therefore, a deeper understanding is of crucial importance on how to manipulate the post-harvest factors with the aim to maintain and/or maximize the seed quality prior to sowing. Post-harvest seed enhancements can improve germination and vigor, protect seed and seedlings from biotic and abiotic stress, and improve seed singulation and precision seeding.
This Special Issue focuses on the development and assessment of post-harvest methods in determining the seed quality of crops, and enhancing seed and seedling performance resulting in high and stable quality. This issue on Modern Seed Technology will include interdisciplinary studies embracing agriculture with disciplines of biology, chemistry and engineering. Research articles will cover a broad range of seeds from specialty crops, including vegetable crops, ornamental and hemp as well as field crop, and seeds from other managed ecosystems. All types of articles, such as original research, opinions, and reviews are welcome.

Systemic Uptake of Fluorescent Tracers by Soybean (Glycine max (L.) Merr.) Seed and Seedlings
Abstract: A better understanding of systemic seed treatment uptake was explored into seeds and seedlings using soybean as a model. Fluorescent tracers were used to mimic systemic uptake of agrochemicals applied as seed treatments. The relationship between seed treatment lipophilicity, measured as log P was investigated using 32 fluorescent tracers. Varietal differences were examined with 17 varieties using coumarin 120, a nonionic fluorescent tracer. Fluorescence microcopy and fluorescence imaging using IVIS (in vivo imaging system) was employed for imaging seed and seedling uptake of the fluorescent tracer, rhodamine B and rhodamine 800. Qualitative seed uptake studies revealed that seed and seedlings took up fluorescent tracers representing a wide range of log P and electrical charge. There were large varietal differences with respect to seed uptake, and quantitative uptake studies revealed 4.5 times greater uptake from ‘TMG 4185’ than ‘M 7739 IPRO’. Rhodamine B and Rhodamine 800 seed uptake increased as dosage increased from 0.05% to 0.5%. Rhodamine B uptake into seedlings showed translocation from the seed treatment to different tissues of seedling. Most of the tracer was measured in the hypocotyl and root with lesser amounts in the epicotyl and leaves. Log P is well documented in the literature to model systemic uptake by roots, but log P of the tracers were not related to seed uptake.
Evaluating Seed Treatments to Increase Field Emergence in Low- Phytic Acid SoybeansAbstract: Phytic acid (PA) accounts for the vast majority of phosphorus in soybean [Glycine max (L.) Merr] seeds but is unavailable to mono- and agastric animals. Low-PA soybean varieties have been developed to improve feed efficiency but often exhibit low field emergence, an important agronomic trait. The purpose of this study was to assess effects of both agronomic and seed treatments on field emergence and yield. A total of 12 treatments consisting of two broad spectrum, preplanting fungicides; hydropriming; MicroCel-E; and all possible combinations except the two fungicides were designed to treat four low-PA and two normal-PA soybean varieties. The plots were planted in Blacksburg and Orange, VA in 2014 and 2015 under both irrigated and non-irrigated conditions. Treatment with fungicides Rancona Summit and ApronMaxx and Priming + Rancona significantly improved field emergence relative to the control in 2015, increasing emergence by 6.4-11.6% across varieties. Low-PA variety MD 03-5453, which had the lowest control field emergence, exhibited significantly increased field emergence with both fungicide treatments in 2015. Priming treatments, if significant, were negatively associated with field emergence across Low-PA varieties. The results indicate not only that seed treatments can improve emergence in low-PA soybeans but further suggests that reduced phytic acid in soybean seeds may dramatically decrease seedling vigor after germination.
