Root Axis

The Structure of the mature rape embryo was examined on longitudirna microtome sections, and1, its developmental interpretation is given, based on the author's own studies and literature data. The boundaries between the epicotyl, hypocotyl and radicle are recognized and identified with the limits between the proembryo segments. The radicle Structure and root apical meristem organization are described. In the dermatogen and periblem cell patterns four segments are distinguished, separated successively from the initial cells. Their position is recognized as almost the same on both sides of the root axis and in different embryos. The easily discernible limits between the dermatogen sectors are to be utilized as reference points in studies on the root apical meristem activation and growth during rape seed germination.

Companion Crop

Yields of pure stands of alfalfa (Medicago media Pers.) and bromegrass (Bromus inermis Leyss.) established on summerfallow with and without an Argentine rape-seed (Brassica napus L.) companion crop were compared at Melfort in three tests, each maintained for 4 yr. In all three experiments, yields over the 4-yr period were greater when the forage was established alone, and in two of the three, bromegrass produced more than alfalfa. When established with rapeseed, forages produced much less dry matter in the seedling year than when established alone, and the effects of the companion crop carried over into the following year. Thereafter, the yield differences between the two establishment methods were small and in the final year had disappeared. Argentine rapeseed suppressed forage seedling growth more in the 2 yr with average or cool summers, than in the year with a hot summer. Alfalfa was more severely suppressed than bromegrass in the year with the best growing season.Key words: Bromegrass, alfalfa, rapeseed, companion crops, forage yield, forage establishment
