According to the present invention there is provided an organism growth array device suitable for automated phenotypic analysis of either plants or microorganisms under aseptic conditions and comprising: a plurality of receptacles, each receptacle having a housing comprising first and second open ends and one or more longitudinal sides extending from the first open end to the second open end, wherein at least one of the longitudinal sides is flat, and wherein a portion of each receptacle is fused to the neighbouring receptacle(s) along at least 10% of its length along the longitudinal axis of the receptacle growth medium housed within the housing extending from a first surface of the growth medium, disposed longitudinally towards the first open end of the receptacle to a second surface of the growth medium disposed towards the second open end of the receptacle, wherein generally, in use, the first surface of the growth medium is disposed above the second surface of the growth medium wherein the open ends of each receptacle are individually accessible, preferably for the addition of different compositions and wherein the growth medium of each receptacle is visible, and imagable across the lateral axis of the receptacle and along the longitudinal axis of the receptacle from the first surface to the second surface, and in use the growth of the organism within or into the growth medium is visible and imagable across the lateral axis of the receptacle and along the longitudinal length of the growth medium. There is also provided a method of imaging and/or analysing the development of one or more organisms.La présente invention concerne un dispositif à matrice de croissance dorganismes, approprié pour une analyse phénotypique automatisée soit de plantes soit de micro-organismes dans des conditions dasepsie et comprenant : une pluralité de réceptacles, chaque réceptacle comportant un boîtier possédant des première et seconde extrémités ouvertes et un ou plusieurs côtés lon
