Title

STUDY ON RELATIONSHIP OF HYBRID MAIZE (ZEA MAYS L. CV. SINGLE CROSS 704) FIELD SEEDLING EMERGENCE AND SOME RELATED LABORATORIAL MEASURED TRAITS

Pages

Abstract

 In order to determine the most suitable seed and seedling vigour test of hybrid MAIZE (Zea mays L. Cv. single cross 704) by study and evaluation of seed viability and various seed and seedling vigour indices at three seed sizes(flat, medium and round) for predicting seed and seedling vigour and field performance, this study was carried out in 2000 at field and Central Seed Analysis Laboratory of Seed and Plant Improvement Institute in Karaj. In field, after planting seeds, seedlings emergence time, seedling vigour indices, seedling dry matter and height were measured and data analysis showed that flat seeds produced seedlings with high dry matter, height and field emergence. In laboratory, seeds at three sizes were tested by three vigour test of MAIZE seed, seedling growth vigour test, complex stressing vigour test and cold test. In addition to seed viability, thirteen seed viability and seed and seedling vigour indices including mean time to germination and daily germination speed were determined. Abnormal seedling number in complex stressing vigour test were higher than those at other two vigour tests. CORRELATION among different indices showed that number of emerged seedlings in field had highly significant positive relation with final germination percent, mean time to germination and mean daily germination by seedling growth vigour test, daliy germination speed, mean daily germination, seedling dry weight and seedling vigour index by complex stressing vigour test and mean time to germination and daily germination speed by cold test and abnormal seedling number evaluated by complex stressing vigour test.
