Wheat spike fertility : inheritance and relationship with spike yield components in early generations by Martino, Diana Laura, Abbate, Pablo Eduardo, Cendoya, Maria Gabriela, Gutheim, Florencia, Mirabella, Nadia Estefania, Pontaroli, Ana Clara

“…In wheat, grain number is considered as the product of spike dry weight (SDW) and the number of grains per unit of SDW, that is an indicator of spike fertility (SF). …”

Drivers and triggers of international food price spikes and volatility by Tadesse, Getaw, Algieri, Bernardina, Kalkuhl, Matthias, von Braun, Joachim

“…To this end, it distinguishes between root, conditional, and internal drivers of price changes using three empirical models: (1) a price spike model where monthly food price returns (spikes) are estimated against oil prices, supply and demand shocks, and excessive speculative activity; (2) a volatility model where annualized monthly variability of food prices is estimated against the same set of variables plus a financial crises index; and (3) a trigger model that estimates extreme values of price spikes and volatility using quantile regressions. …”

When prices spike: Identifying excessive volatility in fertilizer markets by Yao, Feng, Hernandez, Manuel A.

“…Using a nonparametric location-scale approach to model price returns, we quantify the conditional value-at-risk (CVaR)—the high return threshold exceeded with low probability—to identify excessive price spikes in potash, urea, and di-ammonium phosphate (DAP) markets. …”

Frost damage on grain number in wheat at different spike developmental stages and its modeling by Martino, Diana Laura, Abbate, Pablo Eduardo

“…Frosts may damage wheat (Triticum aestivum L.) spikes and severely reduce their yield. The objective of this study was (i) to quantify the level of susceptibility to frost at different spike developmental stages, and (ii) to develop a theoretical-empirical model to estimate successive frosts damage on grain number (GN) at different spike and crop developmental stages based on the meteorological characteristics of the event. …”

Laboratory-scale evaluation of composite spiked samples for erwinia amylovora detection in asymptomatic plants by Catalá-Senent, J. F., Penyalver, Javier, Navarro, Luis, Baranauskaite, L., Gorris, María T., López, María M., Marco-Noales, Ester

“…Thereafter, using the single spiked samples that were positive for any of the techniques used, composite spiked samples were prepared by adding to single spiked samples increasing amounts of plant material. …”
