Evaluation of Different Cultivars of Tuberose (Polianthes tuberosa L.) under Humid agro Climatic conditions of Goa

Abstract

Tuberose (Polianthes tuberosa L.) is one of the most important tropical bulbous-ornamental cultivated for production of long-lasting flowers spikes. Adaptation and acclimatization of different cultivars under humid agro-climatic conditions of Goa are to be confirmed for their better performance. The present investigation was conducted to evaluate the performance of tuberose cultivars under agro-climatic conditions of Goa during 2014- 2017. Five single and six double cultivars of tuberose were evaluated during the study period. All the cultivars differed in their growth and flowering behaviour. Among the single cultivars, evaluated, maximum number of florets per spike (47.00) was observed in Pune local whereas spike-length (75.59 cm) was maximum in Mexican Single. Among the double cultivars, evaluated, maximum plant height (52.21 cm) and maximum number of leaves per plant (59.63) were recorded with cultivar Arka Suvasini. Leaf length was significantly higher (52.93 cm) in Pearl double whereas leaf width (2.04 cm) was maximum in Calcutta Double. Days to appearance of flower spike were earlier in Arka Suvasini. Minimum days taken for opening of basal floret (84.88 days) were recorded with cultivar Arka Suvasini. Spike girth (0.68 cm), Spike fresh-weight (69.06 cm), floret stalk-length (3.6 cm), floret diameter (5.24 cm), weight of individual floret (3.49 g) and vase life (7.93 days) was significantly maximum in Cv. Arka Suvasini followed by Pearl Double. Based on the performance evaluation cv. Mexican Single among single types and cv. Arka Suvasini and Pearl Double among double types could be recommended for commercial cultivation under agro climatic conditions of Goa.

Evaluation of tuberose genotype IIHR 17-23SP-08 (IC0642158) for flower yield, quality and response to biotic stress

“…Variation among the tuber ose cultivars for the shelf life may be attributable to the hereditary traits, which is further interpreted by prevailing climatic conditions. Safeena et al (2019) reported the presence of genotypic variation in post-harvest life of tuberose.…”

Xenomyrothecium tongaense PTS8: a rare endophyte of Polianthes tuberosa with salient antagonism against multidrug-resistant pathogens

“…Because of aromatic compounds, they are mostly used in the perfume industry. Furthermore, the plant comprises a variety of secondary metabolites, including steroid glycosides and flavonoids, whereas the flower mostly contains terpenoid derivatives and benzoid (Fan et al, 2018;Safeena et al, 2019;Alghuthaymi et al, 2021). As a result, there is an urgent need for novel antibacterial drugs to combat the increasing range of illnesses.…”
