GERMINATION AND VIGOR OF INDUSTRIALLY TREATED MAIZE SEEDS

Ipê Agronomic Journal, 2019
The industrial seed treatment combines the application of insecticides, fungicides, nematicides, micronutrients and other products. However, seed submission to the combination of several products can cause phytotoxicity, resulting in reduced viability and vigor, which is directly proportional to the increase in the storage period of the material. Thus,

Influence of seed size on germination and vigor of seedlings of Camu-Camu

Scientia Agropecuaria, 2017
Camu-camu (Myrciaria dubia) is a fruit species native to the Amazon and its economic importance is proven because the fruit contains high content of ascorbic acid. The objective of this work was to evaluate the germination and vigor of seedlings obtained from seeds of different sizes of two camu-camu populations.
