Variation in growth, production and quality attributes ofPhysalisspecies under temperate ecosystem

Abstract

Variation in growth, production and quality attributes of Physalis species under temperate ecosystem. Abstract-Introduction. Diverse fruit crops with a high value reduce the risk of crop failure and offer alternatives to farmers and the market. The scope of profitable production with such quality crops along with environmental concerns make the evaluation of new species desirable. The aim of our study was to determine the most appropriate species of Physalis for small-scale commercial production in the temperate climate of western Himalayan regions. Materials and methods. Four Physalis species, viz., P. peruviana, P. ixocarpa, P. pruinosa and P. nicandroides, were field-grown during 2010-2011 in the experimental field of the Central Institute of Temperate Horticulture, Srinagar, India, to determine the most appropriate species of Physalis suitable for a temperate climate. Results and discussion. All the species tested produced vegetative growth, flowered and fruited; however, they differed significantly. The number of basal shoots was found to be maximum for P. pruinosa (6.37), whereas the maximum number of prickles per shoot was recorded as maximum for P. nicandroides (6.48). The number of points of attachment varied significantly with species, and the maximum was recorded for P. pruinosa and P. ixocarpa (7.16 for each); the maximum size of fully developed leaves (146.8 mm) and overall plant height (168.27 cm) were recorded for P. pruinosa. Physalis pruinosa and P. ixocarpa were found to exhibit vigorous growth under a temperate climate. Significant differences were recorded for fruiting, flowering and yield potential among the Physalis species. The minimum days taken for bud burst were reported for P. nicandroides (23.55) and P. ixocarpa (24.41). Similarly, the minimum days taken to reach maturity were reported for P. peruviana (64.96). The maximum number of fruits per plant (260.23), length of fruit (33.83 mm), average fruit weight (37.19 g), husk weight (0.32 g), fruit husk ratio (121.27), maximum fruit firmness (43.96 Relative Index) and yield (9.96 Relative Index) were recorded for P. pruinosa. Significant variation was recorded in quality attributes. The highest total soluble solids were found for P. nicandroides (8.46°Brix), whereas the minimum total titrable acidity (0.35%) and maximum ascorbic content (38.41 mg•100 g-1) were recorded for P. peruviana. The 'L' value of fruits, showing brightness, was recorded as the highest for P. peruviana (58.97), whereas fruits of all the species showed a negative 'a' value, indicating that none of them produced redness; however, the 'b' value, indicating yellowness, was maximum for P. pruinosa (18.72).

“…The L* values were higher than those found by Singh et al (2014), and the b* parameter was similar. The Croma value was 90.38 and hue was 58.76.…”

Development of plant regeneration and Agrobacterium tumefaciens-mediated transformation methodology for Physalis pruinosa

“…Physalis most recognizable as food crops are groundcherry (P. pruinosa), goldenberry (P. peruviana), and tomatillo (P. ixocarpa). P. pruinosa originated in Eastern North America, whereas P. peruviana and P. ixocarpa originated in Peru and Mexico, respectively (Singh et al 2014). All three of these Physalis species are primarily consumed as fresh fruit, but P. pruinosa and P. peruviana are also processed to make jams, juices, raisins, and snack products (Puente et al 2011).…”

“…Physalis pruinosa is of special interest for our work because of its potential as a specialty fruit crop that could provide farmers, namely in temperate regions based on its origins, with an additional source of income that would be further spurred by the growing consumer demand for new and unique fruits (Singh et al 2014). One advantage of P. pruinosa from an agricultural standpoint is it can be grown in a wide variety of soil types with successful crop production even in poor, sandy conditions (Wolff 1991).…”
