ROTHM.)* Marzena Błażewicz-Woźniak1, Dariusz Wach1, Agnieszka Najda2, Sylwia Mucha1 1 Department of Cultivation and Nutrition of Plants 2 Department of Vegetable Crops and Medicinal Plants University of Life Sciences in Lublin, Poland ABSTRACT Hyacinthoides hispanica (Mill.) Rothm. is a typical spring geophyte and has been cultivated for a long time in gardens as an ornamental bulbous plant. Bulbs are not only the storage and dor- mant organs, but also a means for the plant’s vegetative reproduction. In Poland, due to the climate, the wintering and reproduction of this plant can be a problem. The aim of the study was to determine the effect of foliar nutrition using phosphorous fertilizer and soil mulching on the formation of bulbs and content of some components in leaves and bulbs of H. hispanica. To this end, a field experiment was carried out in 2010-2012. Mulching the soil with pine bark had a beneficial effect on the weight of bulbs in the core, the average weight of one bulb and the weight, length, diameter and circumference of the largest bulb from the H.

  • Southwestern Rare and Endangered Plants: Proceedings of the Fourth
    Conservation Implications of Spur Length Variation in Long-Spur Columbines (Aquilegia longissima) CHRISTOPHER J. STUBBEN AND BROOK G. MILLIGAN Department of Biology, New Mexico State University, Las Cruces, New Mexico 88003 ABSTRACT: Populations of long-spur columbine (Aquilegia longissima) with spurs 10-16 cm long are known only from a few populations in Texas, a historical collection near Baboquivari Peak, Arizona, and scattered populations in Coahuila, Chihuahua, and Nuevo Leon, Mexico. Populations of yellow columbine with spurs 7-10 cm long are also found in Arizona, Texas, and Mexico, and are now classified as A. longissima in the recent Flora of North America. In a multivariate analysis of floral characters from 11 yellow columbine populations representing a continuous range of spur lengths, populations with spurs 10-16 cm long are clearly separate from other populations based on increasing spur length and decreasing petal and sepal width. The longer-spurred columbines generally flower after monsoon rains in late summer or fall, and occur in intermittently wet canyons and steep slopes in pine-oak forests. Also, longer-spurred flowers can be pollinated by large hawkmoths with tongues 9-15 cm long. Populations with spurs 7-10 cm long cluster with the common golden columbine (A. chrysantha), and may be the result of hybridization between A. chrysantha and A. longissima. Uncertainty about the taxonomic status of intermediates has contributed to a lack of conservation efforts for declining populations of the long-spur columbine. The genus Aquilegia is characterized are difficult to identify accurately in by a wide diversity of floral plant keys. For example, floral spurs morphologies and colors that play a lengths are a key character used to major role in isolating two species via differentiate yellow columbine species in differences in pollinator visitation or the Southwest.

  • Networks in a Large-Scale Phylogenetic Analysis: Reconstructing Evolutionary History of Asparagales (Lilianae) Based on Four Plastid Genes
    Networks in a Large-Scale Phylogenetic Analysis: Reconstructing Evolutionary History of Asparagales (Lilianae) Based on Four Plastid Genes Shichao Chen1., Dong-Kap Kim2., Mark W. Chase3, Joo-Hwan Kim4* 1 College of Life Science and Technology, Tongji University, Shanghai, China, 2 Division of Forest Resource Conservation, Korea National Arboretum, Pocheon, Gyeonggi- do, Korea, 3 Jodrell Laboratory, Royal Botanic Gardens, Kew, Richmond, United Kingdom, 4 Department of Life Science, Gachon University, Seongnam, Gyeonggi-do, Korea Abstract Phylogenetic analysis aims to produce a bifurcating tree, which disregards conflicting signals and displays only those that are present in a large proportion of the data. However, any character (or tree) conflict in a dataset allows the exploration of support for various evolutionary hypotheses. Although data-display network approaches exist, biologists cannot easily and routinely use them to compute rooted phylogenetic networks on real datasets containing hundreds of taxa. Here, we constructed an original neighbour-net for a large dataset of Asparagales to highlight the aspects of the resulting network that will be important for interpreting phylogeny. The analyses were largely conducted with new data collected for the same loci as in previous studies, but from different species accessions and greater sampling in many cases than in published analyses. The network tree summarised the majority data pattern in the characters of plastid sequences before tree building, which largely confirmed the currently recognised phylogenetic relationships. Most conflicting signals are at the base of each group along the Asparagales backbone, which helps us to establish the expectancy and advance our understanding of some difficult taxa relationships and their phylogeny.

The apetalous velopment was established before the diversification of extant condition, however, appears to be the result of parallel or angiosperms. Then, during evolution, this program has been fi convergent evolution with unknown genetic causes. Here we modi ed in different directions and to varying degrees, giving show that within the buttercup family (Ranunculaceae), apetalous rise to the production of a huge variety of petals and petaloid genera in at least seven different lineages were all derived from structures (6, 17).

    SRGC ----- Bulb Log Diary ----- ISSN 2514-6114 Pictures and text © Ian Young th BULB LOG 2321.....................9 June 2021 The changing of the seasons continues as the leaves on the trees emerge, expand and provide us with a wonderfully colourful canopy. This wave of colour above our heads looks especially beautiful when seen in sunshine against a clear blue sky and its emergence coincides with the changing of the flora at ground level. The early flowering plants that took advantage of the open skies to grow and flower before the leaf canopy emerged have completed their growth cycle and have already gone underground or are in retreat to be replaced with some of the woodland species whose flowering time coincides with the leaf growth on the trees. Here I am jumping back to March to both remind you of the scene when the earliest of the bulbs were in flower and to show the ugly stump of one of the very first plants we grew, an Acer palmatum 'Dissectum Atropurpureum’ which at approaching fifty years old was one of the original plants in the garden. Sadly in recent years it has been suffering from die back and Coral Spot fungus to the extent that we decided it was time to take drastic action and cut it right back, removing all the dead wood until all we were left with was a rather ugly stump. You may not notice at this time of year but low down on the right hand side of the stump there is growth in the form of a new network of branches that grew during last year – they are more obvious in some of the next pictures where they are coming into leaf.
