Use of Multispectral Imaging in Varietal Identification of Tomato
Multispectral imaging is an emerging non-destructive technology. In this work its potential for varietal discrimination and identification of tomato cultivars of Nepal was investigated. Two sample sets were used for the study, one with two parents and their crosses and other with eleven cultivars to study parents and offspring relationship and varietal identification respectively. Normalized ca...
متن کاملChange in carotenoids and antioxidant vitamins in tomato as a function of varietal and technological factors.
The change in the carotenoid and bioantioxidant content of tomato as a function of varietal and technological factors was investigated in the present work. No great differences were found between cultivars for fresh consumption (salad tomatoes) and those for processing in ascorbic acid content. The concentration of ascorbic acid ranged between 14.6 and 21.7 mg/100 g fresh weight of ripe tomato ...
متن کاملThe never ripe mutation blocks ethylene perception in tomato.
Seedlings of tomato fruit ripening mutants were screened for their ability to respond to ethylene. Ethylene induced the triple response in etiolated hypocotyls of all tomato ripening mutants tested except for one, Never ripe (Nr). Our results indicated that the lack of ripening in this mutant is caused by ethylene insensitivity. Segregation analysis indicated that Nr-associated ethylene insensi...
متن کاملEffect of Induced Mutation for Varietal Improvement in Some Local Grapevine Cultivars
Grape is important crop with high nutritional value, however there is a great need for improving the quality of the crop. Cultures were maintained in vitro on MS medium supplemented with 2.5 mg/L BAP+ TDZ 3.0 mg/ L. The effect of different doses of gamma irradiation as well as chemical mutagenesis by Sodium azide was studied. It was noted that doses up to 5 Gy helped to increase plant height fr...
متن کاملVarietal Trial on Palmarosa
Field and laboratory investigations were undertaken at Nagarjun Medicinal Plants Garden from 1984 - 1987 with object to find out the suitable variety of palmarosa having high yield of foliage and oil. From the pooled analysis the variety IW - 3631 showed highest dry foliage yield (10271 KG / ha) which was significantly superior over all varieties i.e, IW 3632, IW-3630, IW RRL (B) - 65 and IW - ...
