Pre-Emergence Rotting of Peas in South Australia [PDF]
Australian Journal of Biological Sciences, 1964 Laboratory tests have shown that individual wrinkle-seeded pea seeds vary in their ability to continue vigorous growth after germination. After the radicle has broken through the testa, SOme produce normal seedlings, some fail to develop further, while others afe intermediate between these extremes and produce stunted seedlings. Thus some seeds capable

HELIOSEISMOLOGY OF PRE-EMERGING ACTIVE REGIONS. III. STATISTICAL ANALYSIS [PDF]
The Astrophysical Journal, 2014 The subsurface properties of active regions prior to their appearance at the solar surface may shed light on the process of active region formation. Helioseismic holography has been applied to samples taken from two populations of regions on the Sun (pre-emergence and without emergence), each sample having over 100 members, that were selected to ...
