1. EFFECTS OF GENOTYPE, EXPLANT ORIENTATION, AND WOUNDING ON SHOOT REGENERATION IN TOMATO.

Abstract

Effects of genotype and explant orientation on shoot regeneration from cotyledonary explants of tomato were studied using 10 commercially important cultivars. The explant orientation affected shoot regeneration in all the tested genotypes. Cotyledons placed in abaxial (lower surface facing down) orientation consistently produced better shoot regenerative response and produced greater numbers and taller shoots compared to those inoculated in adaxial (upper surface facing down) orientation. Genotypic variation in terms of shoot regeneration response, number of shoots, and shoot height was apparent. Wounding of cotyledonary explants increased shoot regeneration response. However, shoot height was much lower in shoots regenerated from wounded explants compared to those that originated from intact cotyledons. Shoots produced from wounded cotyledons were abnormal in their form and structure. [ABSTRACT FROM AUTHOR]

Abstract

Background Majority of the post-harvest agri-residues from agricultural activity in Punjab, India, is burnt in the field resulting in the loss of soil fertility and release of large amounts of air pollutants. In an effort to reutilize the selenium-accumulated waste wheat and paddy straw from seleniferous region of Punjab, two varieties of edible mushrooms, Pleurotus sajor-kaju and Volvariella volvacea, were cultivated on Se-rich wheat and paddy straw, respectively.
