TLDR
In this paper, the authors studied the seed deterioration patterns of four bambara groundnut landraces stored in packages with different permeability in an open storage system for up to 6 months.Abstract:
Bambara groundnut (Vigna subterranea (L.) Verdc) is a potential commodity to be developed in Indonesia, however, the production is done only once a year, therefore, it needs proper seed storage. The aim of this research was to study seed deterioration patterns of four bambara groundnut landraces stored in packages with different permeability in an open storage system for up to 6 months. This experiment was conducted from November 2015 to July 2016 at Seed Technology Laboratory, Department of Agronomy and Horticulture, IPB. Stages of experiment as follow: calculation of packaging permeability, seed storage, preparation and fitting data to regression equation.The packaging used in the study is aluminum foil, pp plastic and plastic sacks which have measured its permeability. The result showed that the seed deterioration of four bambara groundnut landraces in three packaging permeability has common sigmoidpattern with equation model: y = a / {1 + exp ((x + b) / c)}. The seed deterioration pattern based on SG and EC variables with the faster rate of decline occurred in Sumedang landrace packed in plastic sack (permeability = 1.4681 g/day m2 mm/Hg), thus having a shorter storability. The slower rate of decline occurred in Gresik landrace packed in aluminum foil (permeability = 0.098 g/day m2 mm/Hg), this means that it has a longer storability.read more

A New Generalized Logistic Sigmoid Growth Equation Compared with the Richards Growth Equation
TL;DR: The new sigmoid equation is more suitable when initial growth is believed to be generally close to exponential, when estimates of maximum relative growth rate are required, or for generic growth simulations.

Bambara groundnut (Vigna subterranea (L.) Verdc.)
TL;DR: The Bambara groundnut (Leguminosae) is an annual short-creeping herbaceous plant that is either bunched or semibunched as mentioned in this paper, and the seeds are variously coloured, some being white, cream or brown, others being red or mottled; a few are black.

Structural mechanics of seed deterioration: Standing the test of time
TL;DR: The perspective of seed maturation and post-harvest treatment is presented as an exercise in engineering design for a structure that must persist through time and fluctuating conditions to quantify differences among seed structures that contribute to their tendency to age.

TL;DR: The presence of Phomopsis sojae fungus in soybean seed samples submitted to the EC test may be the cause of misleading results.
