Seedling stems were severed above the unifoliolate leaves and inoculum was applied to the cut surface. Stem lesion lengths were measured at 1, 2 and 3 wk following inoculation. The mean lesion length on seedlings inoculated 2 wk after planting (27.2 mm) was significantly less than seedlings inoculated 4 wk after planting (44.5 mm). Based on mean lesion length, Williams was the most susceptible variety followed by Harosoy. AC Hime, Coles and Leo were equally resistant. Stem canker development measured at 2 and 3 wk following inoculation was negatively correlated with stem moisture at the time of inoculation suggesting that stem moisture is important in the development and severity of stem canker. Key words: Diaporthe phas...

Two of the taxa are common weeds of cultivated fields and other ruderal sites including grassland and woodland edges. These are Oxalis strictaL. and O. dillenii Jacq. ssp. dillenii. The other two taxa are problem weeds in greenhouses, and sometimes escape locally to establish outdoor populations in Canada (Oxalis corniculataL. and O. dilLenii ssp. filipes). Key words: Weed biology, wood-sorrels, oxalides, Oxalis spp., distribution La biologie des mauvaises herbes canadiennes. 71- Oxalis stricta L., O. corniculata L., O. dillenii Jacq. ssp. dillenii eL O. dillenii Jacq. ssp. filipes (Small) Eiten. Titre abrege: Taxons d'Oxalis. Nous decrivons la biologie de quatre taxons d'Oxalis etroitement apparentes (y compris deux sous-espesces) du groupe des Corniculatae (oxalides d fleurs jaunes). Deux de ces taxons sont des mauvaises herbes des champs cultives et des autres habitats ruderaux, y compris les prairies et I'oree des forets. Il s'agit d'Oxalis stricta L. et d'O. dillenii Jacq. ssp. dillenii. Les deux autres posent des problemes dans les serres et s'echappent parfois pour etablir des populations locales d l'exterieur au Canada; ce sont Oxalis corniculata L. et O. dillenii ssp. filipes.

Endl. were recorded at five natural populations during regular visits occurring 3-6 times per year over a period of 3-6 years. Plant gender was quantified and calculated over all seasons and all reproductive sessions. Two major ...

The plains and wadi habitat types had been regularly disturbed because of cycles of shifting cultivation. When land was prepared for cultivation, seedlings and juvenile plants were removed, leaving only larger adult plants, and, therefore, unstable tree populations, lacking juveniles, and growing in fallow lands. A. amara and A. senegal were more abundant than A. leiocarpus and B. aegyptiaca. The healthiest populations, with more juvenile recruits, were found in the grazing lands at higher elevations. However, A. amara and A. senegal showed stable size structure in both grazing and fallow lands. In general, in the four study species, we see a decline in growth and reproduction (with growth measured as tree height and number of...
