Kura clover (Trifolium ambiguum M. Bieb.) is a rhizomatous perennial legume that is often challenging to establish from seed. Our objectives were to evaluate the effect of planting date (early April, late April, and mid-May), plant material (rhizomes and rhizomes with buds), and rhizome planting density (11, 44, and 178 plants m-2) on establishment of Kura clover. Establishment of the clover was enhanced by early April planting using rhizomes with buds. Kura clover populations increased with increased rhizome planting densities. Establishment of Kura clover at a rhizome density of 178 rhizome m-2 has the potential to provide yield and stands similar to broadcast seeding. Key words: Kura Clover (Trifolium ambiguum M.

Persistent legumes are needed for livestock production in the northern U.S.A. and Canada. We compared forage yield, forage quality and stands of kura clover (Trifolium ambiguum M. Bieb.), a rhizomatous perennial legume, with commonly grown forage legumes. Kura clover had lower initial stands and yields than most other legumes, but was ultimately among the highest yielding legumes and had greater stand persistence and higher forage digestibility than other legumes when subjected to a diversity of cutting schedules.

Baker, J. M. 2012. Vegetative propagation of kura clover: a field-scale test. Can. J. Plant Sci. 92: 1245–1251. Kura clover (Trifolium ambiguum M. Bieb.) is a potentially valuable forage legume, but it has been underutilized. A major reason is the difficulty of establishing it from seed. Since kura is rhizomatous, there have been attempts to propagate it vegetatively, but no reports of success at the field scale. Two harvesting methods were tested to transplant material from a mature 17-ha field to a newly tilled 17-ha field: a bermudagrass sprigger that harvests bare rhizome sprigs, and a potato digger that harvests crowns and rhizomes, along with soil. The harvested propagules were distributed over the new field in July 2010 with a manure spreader, then disked and packed. Survival and growth were observed for the remainder of 2010 and through 2011, and recovery of the source field was also monitored. The material harvested with the sprigger did not compete well with weeds and had virtually disappeared by midsummer 2011, but the material harvested with the potato digger thrived, steadily increasing to nearly 80% of the biomass in the new field by the 3rd cutting in summer 2011. Properly done, vegetative propagation is a viable option for kura clover establishment.

Superior Clones

Even though the Lavandula species may be propagated by seeds, it should not be the preferred propagation method because it causes a great lack of uniformity. On the other hand, asexually propagated lavender crops would provide more homogeneous crops, and clones from high quality plant material would increase the odds for obtaining a higher quality essential oil. However, problems such as poor rooting and restrict market availability for superior clones have been a problem in vegetative propagation of the Lavandula species. The objective of this work was to define which type and size of cutting is more adequate for cutting propagation of L. dentata, a very productive Lavandula species. Cuttings with 5, 8, 10 or 13 cm and from the apical or basal parts of stems cut from L. dentata stock plants were placed in Plantmax HT® filled polystyrene foam trays and kept under intermittent mist system for two months. Averages of root number, length of the longest root, fresh and dry root weight, and percentage of rooting were evaluated. Apical cuttings combined 97.9% rooting with an average of 13.2 roots per cutting and basal cuttings 93.7% rooting with 2.98 roots per cutting. Apical cuttings with at least 10 cm in length were considered the most adequate for cutting propagation of L. dentata.

This investigation was carried out at the Experimental Farm of Assiut University during the summers of 2000 and 2001 to study the responses of two sunflower hybrids (Vidoc and Euroflora) to planting dates (May 1st, June 1st and July 1st) and planting densities (55,533, 83,300 and 166,600 plants/ha). The results indicated that the two varieties differed highly significantly in all studied traits except oil yield/ha. The highest seed yield (3.64 t/ha) was obtained with the variety Vidoc. In addition, the results revealed that the planting date exerted a highly significant influence on all vegetative growth traits along with yield and its components. Increasing plant density increased the seed and oil yield/ha. By contrast, the stem diameter, head diameter, 100-seed weight and seed yield/plant decreased with increasing plant density. The interaction between varieties and plant density had a highly significant effect on head diameter. The greatest head diameter (20.06 cm) was recorded for the variety Vidoc planted at lower density. Concerning the interaction between planting density and planting date, the highest seed yield (4.47 t/ha) was obtained from dense plants at the early sowing date, and the highest oil % (45.32) at the late planting date and the lowest plant density. The second order interaction exerted a highly significant influence on stem and head diameter in addition to seed yield/plant, where the highest value (78.13 g/plant) was obtained with the variety Vidoc planted on May 1st at the lowest plant density.

This experiment was conducted to evaluate the mineral contents of I. zollingeriana growing with different planting densities. The experiment was conducted in a randomized block design with three different planting densities (8,000 plants per ha, 13,333 plants per ha, and 20,000 plants per ha) and 3 replication. Plant biomass was analyzed for macro and micro mineral contents as well as Ca:P ratio. The results showed that increased planting densities significantly increased (p<0.05) P, Cu, and Cr contents, but decreased Ca and Na contents  had no significant effect  on Mg, K, Mn, Zn and Fe contents. Furthermore, the increased planting densities significantly decreased (p<0.05) uptakes of Ca, K, Mn, and Fe by the plants, but increased (p<0.05) the uptakes of Cu and Cr. Meanwhile, the uptakes of P, K, Na, and Zn were not affected by planting densities. Based on the results of this study, it can be concluded that the planting density of I. zollingeriana should be maintained in 8,000 plants ha-1 to maintain the content and uptake of mineral in forage crops.

Abstract Several poplar species within a section, but also between sections, are cross-compatible, thus a high number of interspecies-hybrids occur naturally or have been artificially produced during the last 100 years. Very often, systematically kept records on the production or vegetative propagation of poplar hybrids and/or clones have not been available to date. Hence the origin of the poplar plant material used for the generation of hybrids or clones is not quite clear in many cases, thus making the differentiation between the clones a difficult task. Therefore, genetic markers are needed to clearly identify and differentiate the species and hybrids in the genus Populus, including both identification of existing clones and the breeding of new ones. One aspect of this study is therefore to develop molecular markers for the identification and differentiation of species, hybrids, and clones of the genus Populus.

In 1986 and 1987, five mulch/tunnel treatments (bare soil (BS), black mulch (BM), transparent mulch (TM), black mulch/perforated transparent tunnel (BMT), and transparent mulch/perforated transparent tunnel (TMT)) were factorially combined with three planting dates representing very early (10 May), early (21 May) and normal (3 June) dates for Southern Québec. Following a late frost after the first two planting dates of 1986, all treatment combinations resulted in significant improvements in survival rates over BS plants. Only the TMT treatment proved justifiable for the earliest planting date across both years, though there were no significant differences between TMT and BMT treatments under milder growing conditions. Tunnel treatments proved superior to their mulch-only counterparts for earlier plantings and/or the cooler season (1986). TM resulted in superior yields over BM for all planting dates in 1986, and for no planting dates in the warmer season. TM generally resulted in yields superior to that of BS. BM treatments rarely improved early yields over BS, though total yields were improved in 1986.Key words: Cucumber, planting date, mulch, tunnels

Meadow saffron (Colchicum autumnale) is an undomesticated plant from whose seeds the alkaloids colchicine and colchicoside are extracted and used pharmaceutically. Research was conducted towards domesticating meadow saffron in which inter- and intra-genetic variability of accessions was studied. Colchicine, 3-demethylcolchicine and colchicoside were assayed in plants of six accessions collected from natural sites in eastern France. These were cultivated at two sites and studied during 1 or 2 yr. Plants from 70 initial transplanted corms of one accession were studied individually for 4 yr to determined intra-accession variability and, as spontaneous vegetative multiplication of corms occurred, comparisons among plants from one initial transplanted corm were also made. For the main characteristics, seed dry weight (SDW) per plant, alkaloid content and colchicine:colchicoside ratio, the inter-accession variability was lower than the intra-accession variability. The results suggest that vegetative propagation of selected genotypes could improve alkaloid content by about 80% and improve SDW per plant by about 300%.
