Plantago Major L., P. Media L. and P. Lanceolata L.

THE BIOLOGY OF CANADIAN WEEDS.: 47. Plantago lanceolata L.

“…Narrow-leaved piantain is one of the most palatable species to sheep (Milton 1933). Sheep will ' 'actually chisel the crowns out of the ground using the lower incisors" (Sagar and Harper 1964 (Milton 1943) and it was once sown extensively on thin soils to prevent erosion (Sagar and Harper 1964). In Germany, P. lanceolata is a recommended constituent of pasture mixtures because it improves animal health and milk flavor (Heeger 1949 (Blom 1978 (Barber et al 1968) and also arrest flowering (Sagar and Harper 1964).…”

“…(b\ Substratum -P. lanceolata occurs on a wide range of soil types (Sagar and Harper 1964) but is most common on neutral to basic soils (Bassett and Crompton 1968). Zeiner ( 1946) claimed that it was intolerant of acid soils (pH 4.4-4.5) in a study of plant communities after disturbance in Indiana.…”

EXPERIMENTAL ECOLOGICAL GENETICS IN PLANTAGO . V. COMPONENTS OF SEED YIELD IN THE RIBWORT PLANTAIN PLANTAGO LANCEOLATA L.

“…Plantago lanceolata is a short-lived perennial rosette herb with lanceolate leaves (Sagar and Harper, 1964). It produces inflorescences from the axils of the rosette leaves, each inflorescence being terminated by a dense spike of small flowers.…”

Allozyme genetics, self-incompatibility and male sterility in Plantago lanceolata

“…Genetic variation for seed yield is reported by Primack and Antonovics (1981); for photosynthetic response to temperature and irradiance by Teramura and Strain (1979). Sagar and Harper (1964) mention different varieties of P. lanceolata which also points to genetic differentiation.…”
