Abstract

A maiden attempt was made at Horticultural Research Station (HRS), a constituent research unit of Tamil Nadu Agricultural University, located at Yercaud, Salem District, Tamil Nadu, India during 2012-2013 to assess the suitability of various ornamental foliage plant species under Shevroys /Eastern Ghats conditions. Considerable variation was found in quantitative and qualitative parameters among the foliage species. The study recommends Nephrolepis cordifolia and Asparagus sprengeri as suitable liners, while, large-leaved species like Cordyline fruticosa and Philodendron xanadu as background materials in larger arrangements, and the smaller-leaved Dracaena reflexa var. angustifolia for smaller arrangements.

Abstract

An investigation was carried out to evaluate performance of 36 cultivars of cut gerbera (Gerbera jamesonii Bolus ex Hooker F.) in a polyhouse at Horticultural Research Station, Tamil Nadu Agricultural University, Yercaud, during 2008-2010. Significant differences were observed for all the characters studied. Maximum plant-spread (78.02cm) was observed in cv. Robusta. Higher number of leaves was recorded in cv. White Tibet (41.54). Maximum Leaf length and leaf width was recorded in cvs. Golden Gate and Yanara. Maximum number of suckers produced was recorded in cv. Junkfru (7.60). Maximum stalk length was observed in cv. White Tibet (62.62cm), while flower diameter, cut flower production and vase-life were higher in cv. Rosalin. Correlation and path coefficient analysis showed that plant height, number of leaves per plant and number of suckers per plant were the important components of cut-flower yield in gerbera. It may be concluded that cultivars Rosalin, White Tibet, Junkfru and Golden Gate were found to be the best for floral quality and yield, and are recommended for cut-flower production under Shevaroy condition of Eastern Ghats.

Abstract

Performance of 24 orchid species was assessed in the net-house of Horticultural Research Station, Tamil Nadu Agricultural University, Yercaud. Among the species studied, plant height was significantly high (105cm) in Spathoglotts plicata. At the end of the vegetative stage, number of leaves was maximum (30) in Aerides. Leaf was longest (49.8cm) and widest (17.6cm) in Rhyncostylis retusa. Paphiopedilum insigne produced largest flower size (14.4cm across). Pedicel length was highest in Phaius tankervillae (10.3cm) and Renanthera inshootiana (7.1cm). Aerides multiflorum recorded lowest pedicel length (1.24cm). Epidendrum radicans and Spathoglottis plicata produced flowers round the year. Lucia virides recorded maximum life (29 days) on plant, followed by Arachnanthe clarkei (18 days), Dendrobium densiflorum (18 days) and Oncidium flexosum (16 days), while, minimum (6 days) was observed in two orchid species, Aerides crispum and Cattleya sp. Maximum (23 days) vase life was recorded in Lucia virides. Results of the investigation thus reveal that among the 24 orchid species studied, Epidendrum radicans, Lucia virides and Paphiopedilum insigne performed better in terms of vegetative and floral characters under Shevaroy hill condition.

Abstract

A study was conducted on the influence of growth media on development of Asparagus densiflorus 'Meyersii' at Horticultural Research Station, Yercaud during the years 2011-12. The pot experiment was laid out under open condition, with nine set of treatments comprising various combinations of soil, sand, FYM, vermicompost and microbial consortia (Azospirillum, phosphobacteria and Pseudomonas fluorescens). From among the media combinations used, the treatment involving Soil + Sand + FYM + Vermicompost (T3) @ 2:1:1:0.5 (670g+375g+375g+165g) was found to be the best substrate for vegetative and ischolar_main characters like plant height, shoot number, leaflet number, leaflet length, leaflet width, ischolar_main number, ischolar_main length, bulb number, bulb length, bulb width and vase-life in Asparagus densiflorus 'Meyersii'.

Abstract

Gladiolus grandiflorus L. genotypes were evaluated for growth and floral parameters in Eastern Ghats of Tamil Nadu, under Yercaud conditions. Significant differences were recorded for all traits studied. Among 42 genotypes evaluated, 'Pusa Shagun' and 'Pusa Swarnima' recorded quality spikes with higher vase life indicating their suitability for use in floral arrangement, while, genotypes like 'Thumbolina', 'Priscilla' and 'Candyman' were found superior in characters like corm number, corm weight and corm diameter. Taking into account various growth and floral characters of the genotypes studied, Pusa Swarnima, Pusa Shagun, Thumbolina, Priscilla and Candyman can be recommended for cut-flower production in the Eastern Ghats of Tamil Nadu.
