Impact of Growth Regulators on Seed Yield and Quality of Coriander (Coriandrum sativum L.)
Journal Title: Current Journal of Applied Science and Technology - Year 2017, Vol 22, Issue 5
Abstract
Coriander (Coriandrum sativum L.) is an important seed spices crop of family Apiaceae (Umbelliferae) with cross-pollination as mode of reproduction. Coriander is an important seed spice, cultivated in almost states of India and gaining export importance. Plant growth regulators (PGRs) have emerged as magic chemical that could increase agricultural production at an unprecedented rate and help in removing or circumventing many of the barrier imposed by genetics and environment. Therefore considering significance of coriander in national economy, a field experiment was conducted at CCS Haryana Agricultural University, Hisar to study the impact of growth regulators on seed yield and quality of coriander. The research material comprised of four genotypes viz. DH-5, DH-36, DH-228 and DH-246 was grown with three replications in factorial RBD. Two PGRs namely NAA and GA3 each at 50 ppm and a control (water spray) were used as treatments at the time of 50% flowering. The foliar application of growth regulators such as NAA and GA3 at 50 percent flowering was found most effective to enhance the plant height, number of branches per plant, number of umbels per plant, number of seeds per umbel, number of seed per umbellate, seed yield and seed quality parameters such as test weight, standard germination, seedling length, seedling dry weight, vigor index-I & vigor index-II, dehydrogenase enzyme activity, field emergence index and seedling establishment. So, the application of NAA and GA3 was useful in more seed setting, high seed yield and quality of all the genotype. Among all the genotypes, Hisar Anand (DH-5) was found the highest seed yielder followed by Hisar Bhoomit (DH-228), Hisar Surbhi (DH-246) and Hisar Sugandh (DH-36).
