A method for the computer-aided training of an artificial neural network (ANN) for recognizing structural features on objects, by means of which method identified structural features on objects are recognizable rapidly and reliable. That is achieved by virtue of the fact that a convolutional neural network (CNN) having a multiplicity of neurons is used for the training of an ANN for feature recognition on objects. Said network comprises a multiplicity of convolutional and/or pooling layers for the extraction of information from images of individual objects. In this case, the images of the objects are respectively scaled or scaled up and/or down from layer to layer. During the scaling of the images information about the structural features of the objects is maintained, specifically independently of the scaling of the images.

A method includes inserting viable, in vitro cultivated plant material into an empty pocket of a strip element that is formed at least in part of biodegradable material. The strip element has a first and second wall-forming member arranged to at least partly overlap in a longitudinal direction and to not fully overlap in a transverse direction with the first wall-forming member extending past the second wall-forming member. The wall-forming members are fixed to each other along a bonding line to delimit a plurality of pockets and a plurality of spacer areas in an alternating arrangement along the longitudinal direction such that a top side of each pocket is open. The method includes facilitating, without the use of a substrate, at least one of an acclimatization or a root formation of the in vitro cultivated plant material in the plurality of pockets of the strip element.

Described is a method for stimulating vegetative propagation of a potato tuber by exposing a potato tuber to an composition comprising oxytocin and/or a fragment and/or variant of oxytocin possessing oxytocin activity, wherein the exposure of the oxytocin and/or said fragment and/or variant of oxytocin possessing oxytocin activity stimulates the formation and/or growth of at least one potato tuber.

Disclosed is a method for inducing field-planted Ananas comosus to rapidly propagate seedlings, which adopts a new technical management method for practical production of the field-planted Ananas comosus, and comprises: pruning and shaping mother plants of Ananas comosus, performing sterilization and pest prevention on the mother plants of Ananas comosus, promoting germination, performing fertilization, and propagating and culturing strong seedlings, especially implementing application management of plant kinetin, so that a seedling propagation period of the field-planted Ananas comosus is shortened by more than 60 days compared with a natural propagation period, and by means of 2-3 rounds of propagation and harvesting, a propagation coefficient of a single mother plant is improved to reach 12. The method has a high propagation rate, realizes rapid production of a large number of native offset seedlings of Ananas comosus, and greatly improves the production efficiency of Ananas comosus, and reduces a seedling propagation cost.

A method for producing, without the help of a substrate, a plurality of rooted cuttings includes inserting at least one unrooted cutting into pockets arranged successively in a longitudinal direction of a strip element. Each pocket has an opening at a top side facing a transverse direction and a bottom side that is at least partially closed. The strip element is formed at least in part of biodegradable material having a liquid retaining capacity of at least about 100 g liquid per 100 g of biodegradable material dry weight. The strip element has first and second wall-forming members fixed to each other in a spacer area adjacent each pocket and arranged to at least partly overlap in the longitudinal direction and to not fully overlap in the transverse direction. The first wall-forming member extends past the second wall-forming member in the transverse direction at the top side of each pocket.
