Correlation and Regression Analysis of Viability and Vigour Parameters in Coriander (Coriandrum sativum L.)
Journal Title: International Journal of Plant & Soil Science - Year 2017, Vol 20, Issue 2
Abstract
In the present investigation freshly harvested seeds of four genotype of coriander viz., DH-228, DH-246, DH-5 and DH-36 were subjected to study the effect of foliage cuttings and growth regulators on seed yield and seed quality of coriander. Correlation coefficient analysis was employed to find out the correlation and regression analysis of various viability and vigour parameters in coriander viz., standard germination, seedling length, seedling dry weight, vigour index-I, vigour index-II, electrical conductivity, dehydrogenase activity test, field emergence index and seedling establishment. Seedling establishment is positively and significant correlated with Seedling dry weight (0.884**) followed by vigour index-II (0.883**) and whereas, electrical conductivity was found negatively and significant correlation (-0.560**) with the seedling establishment. The maximum value of coefficient of regression (0.781) was obtained for seedling dry weight followed by vigour index-II (0.779), vigour index-I (0.631), dehydrogenase enzyme activity (0.618), field emergence index (0.556), standard germination (0.525), seedling length (0.440) and electrical conductivity (0.313), as these tests are highly correlated with seedling establishment. The maximum value of coefficient of regression (0.931) was found for dehydrogenase enzyme activity followed by seedling length (0.911) and minimum value (0.409) of coefficient of regression was found for standard germination by the only interaction with foliage cuttings, whereas, interaction with growth regulators was found the maximum value of coefficient of regression (0.818) was found for seedling dry weight followed by vigour index-II (0.815). Among all the seed quality parameters seedling dry weight, vigour index-II and standard germination were found highly correlated with seedling establishment for all the genotypes hence they can be used as reliable predictors of seedling establishment.
