Abstracts |
The effects of arbuscular mycorrhiza (AM) in terms of breaking the bud dormancy of grapes cv. Perlette, as well as in hastening flowering, berry set and berry ripening in the crop were determined in a field experiment conducted in New Delhi, India. Eighteen-year-old vines of Perlette, having uniform vigour and growth, planted at 2.5x2.5 m and trained on a telephone system, were inoculated with 3 strains of AM namely Glomus mosseae, Glomus deserticola and Gigaspora calospora when the root system was active in February. Treatments with FYM and inorganic NPK were maintained as controls. The grapevines inoculated with Glomus deserticola took significantly fewer days for bud sprouting, inflorescence emergence, 50% flowering, berry set and ripening compared with all other treatments. The observations are discussed in relation to the observed changes in the soil pH and leaf nutrient status. Hastening of bud sprouting, flowering, berry set and ripening in AM treated plants helped in harvesting the fruits before the onset of rains and reduced the damage due to monsoons. It is suggested that AM strain Glomus deserticola can potentially be included in the fertilizer management practice as an alternative to chemical fertilizers for providing the plant nutrient requirement. |
