Vigour test

Hydropriming has the potential to ameliorate the stress-induced ill effects on yields of the crop plants and quality of seed produced. In the present study, half of the fresh seeds of maize hybrid, PEHM 5 and its parental lines (Female - CM 150, Male - CM 151) were subjected to accelerated aging test for bringing down the viability and vigour, thereby creating low vigour lots while high vigour lots consisted of fresh seeds, which were hydroprimed (30 h at 25°C). Half of the hydroprimed seeds were surface dried while the other half were redried back to the original moisture contents.

Green gram (Vigna radiata L.) is one of the important pulse crops in India. It is widely cultivated throughout India in three different seasons. Eight genotypes of green gram viz, Pusa Vishal, PM-11-9, IPM-2-3, Meha (IPM 99-125), Samrat, IPM-512-1, TMB-37, SML-1822 were primed with GA3 and Ag-nanoparticle for six hours. The laboratory experiment was done in seed testing laboratory, BCKV, West Bengal during 2019 & 2020.

A study was conducted at Chaudhary Charan Singh Haryana Agricultural University, Hisar for determining the ability of various seed vigour parameters to predict the field emergence of 34 varieties of wheat. Twelve seed vigour parameters were evaluated viz. test weight, standard germination, seedling length, seedling dry weight, vigour index-I, vigour index-II, accelerated ageing test, electrical conductivity, tetrazolium test, dehydrogenase activity test, field emergence index and seedling establishment.

Groundnut kernels are highly sensitive to seed deterioration mainly due to their chemical composition and moisture content. During the seed deterioration membrane degradation precedes loss of seed vigour and germination. Membrane degradation is measured by the electrical conductivity of seed leachate.

Combination of Rhizobium and Trichoderma species were studied to document their compatibility their synergism, antagonism under in vitro condition and their effects on the growth of lentil in vivo condition. In respect this, few strains of Trichoderma were isolated from the rhizosphere soil of Pulse crop from different locations of West Bengal and they were tested in vitro and in vivo along with Rhizobium to know the interaction between them and the growth behaviour on lentil.

An experiment was conducted to assess the storability of groundnut (Arachis hypogaea L.) seed lots based on vigour tests during 2015-16. Nineteen seed lots with varying vigour levels based on different germination percentages were taken and replicated four times. The results indicated that seeds with higher vigour were able to retain the vigour for longer period (at the end of storage period of six months). The vigorous lots recorded higher quality parameters at the end of storage period.
