Ergobalansine, a New Ergot-Type Peptide Alkaloid Isolated from Cenchrus echinatus (Sandbur Grass) Infected with Balansia obtecta, and Produced in Liquid Cultures of B. obtecta and Balansia cyperi

Journal of Natural Products, 1990
ABSTRACT.-An EtOH extract Of Cenrhrus echinatus (sandbur grass) infected with Balansia obtlrta, a fungal endophyte of the Clavicipitaceae, has yielded ergobalansine 111, a new ergot- type alkaloid.

Germination and Emergence of Longspine Sandbur (Cenchrus longispinus)

Weed Science, 1989
Longspine sandbur germinated readily after 3 months of storage at 0 to 4 C. Germination was 15 to 82 and 10 to 76% for seed retained by or that passed through a 1.7-mm-mesh screen, respectively, and was greatest in complete darkness near 30 C. Light inhibited seed germination at most of the temperatures tested. Incubating imbibed seed at 40 C and 40/10
