Abstract

This video describes the method to quantify the digestible carbohydrates present in plant tissues. This helps to collect data from various plant tissues to study nutritional ecology, plant-herbivore interactions, and food-web dynamics.

Protocol

1. Plant Collection and Processing After collecting plant samples, flash-freeze samples by dipping plant material into liquid nitrogen with forceps and store at -80 °C. If the plant samples collected are too large to flash-freeze, quickly cool the samples using dry ice and transfer to a -80 °C freezer as soon as possible. The macronutrient content of plant material can change after tissues are separated from the plant, so it is important to freeze plant samples as soon as possible after collection.<…
