Seasonal changes in germinability, dormancy and viability of field bindweed (Convolvulus arvensis) seeds as affected by storage and duration

Abstract

Background Field bindweed (Convolvulus arvensis L.) is a hardy perennial weed currently threatening many agroecosystems and orchard ecosystems in China. It can be spread farther by seed with a long dormancy. Objective This study aimed to evaluate the seasonal changes in germinability, dormancy and viability of field bindweed seeds in the unique arid environment in northwest China. Methods Seeds were subject to burial at various depths in the field, outdoor and indoor storage, or dry- and wet-cold stratification (5 [...]
