Broccoli (Brassica oleracea L. var. italica) is an important, nutritionally rich vegetable crop, but severely affected by environmental stresses, pests and diseases which cause massive yield and quality losses. Genetic manipulation is becoming an important method for broccoli improvement. In the present study, a reproducible and highly efficient protocol(More)
Broccoli (Brassica oleracea var. italica) is an important nutritionally rich vegetable cole crop. Environmental stress, pests and diseases cause enormous yield losses because of a limited gene pool. Genetic manipulation is becoming an important method for broccoli improvement. The objective of the present study was to evaluate the potency of thidiazuron(More)
A rapid and efficient protocol is developed for in vitro plantlet regeneration of Populus deltoides clone G48 using petiole explants. The highest frequency of shoot regeneration (74.75%) from petiole was obtained on MS medium supplemented with 0.50 mg/l BAP and 0.20 mg/l IAA. The regenerated shoots started turning brown and necrotic after 10–15 days in(More)
Biotechnology holds promise for genetic improvement of important vegetable crops. Broccoli (Brassica oleracea L. var. italica) is an important vegetable crop of the family Brassicaceae. However, various biotic and abiotic stresses cause enormous crop yield losses during commercial cultivation of broccoli. Establishment of a reliable, reproducible and(More)
With the advent of molecular biotechnology, plant genetic engineering techniques have opened an avenue for the genetic improvement of important vegetable crops. Vegetable crop productivity and quality are seriously affected by various biotic and abiotic stresses which destabilize rural economies in many countries. Moreover, absence of proper post-harvest(More)
Populus species are important resources for industry and in scientific study on biological and agricultural systems. Our objective was to enhance the frequency of plant regeneration in Himalayan poplar (Populus ciliata wall. ex Royle). The effect of TDZ alone and in combination with adenine and NAA was studied on the regeneration potential of petiole(More)
Irrigation management has gained significance due to growing social needs and increasing command for food grains while the available resources have remained limited and scarce. Irrigation management includes optimal allocation of water for irrigation purposes, optimal cropping pattern for a given land area and water availabilities with an objective to(More)
This paper presents an application of Differential Evolution (DE) to determine optimal crop plan for command area of Pamba-Achankovil-Vaippar (PAV) link project, so as to maximize the net irrigation benefit. The mathematical model of the problem is linear in nature subject to various constraints due to availability of total land area, water, fertilizers,(More)
Recent RHIC data have suggested an interesting scenario where jets, after being formed in the very first instants of the nuclear collision, interact strongly and are absorbed by the hot and dense matter subsequently created. In this respect, electromagnetic signals constitute another class of penetrating radiation. We first propose the study of large mass(More)
