Abstract

Priming is a process that controls the process of hydration of seeds for the ongoing metabolic processes before germination.  Research on   priming   was conducted  at  ICERI seed laboratory  from May to September 2009  to evaluate the  effect of different priming methods on  wheat seed vigor. Physical properties and chemical composition of seed were evaluated before seeds were treated. The priming treatment were conducted by soaking 250 g of seed in  500 mL of  solution for hydropriming and halopriming.  Two seed lots of Nias and Dewata variety were subjected to heated and unheated  distilled water for 12hours and subjected  to  KCl and CaCl2  at 10, 20, and 30 ppm and unprimed seed. The experiment were arranged in completely randomized design,  replicated thrice.  Vigor evaluation by observed  seed germination, simultaneity growth, germination rate, seedling dry weight, electric conductivity of seed  leakage and  length of primary root.   The results showed that highest  germination,  simultaneity growth, seedling dry weight, and length of primary root,  were priming treatment    with  KCl  30 ppm  and CaCl2  20 and 30 ppm.  Priming  with distilled  water for 12 hours gave  higher  germination percentage  and  simultaneity growth.   Keywords : priming, wheat, seed, vigor

Abstract

Matriconditioning treatments have been reported to improve seed and seedling qualities of many crops after certain storage periods. The research was conducted to evaluate different matriconditioning substances on seedlings characteristics of seeds that previously stored in different periods. The research was carried out from October 2015 to April 2016 at the Indonesian Cereal Research Institute (ICERI). The experiment was arranged in factorial completely randomized design to facilitate the combination of two factors. The first factor was seed storage period, i.e. 4, 36 and 72 months, while the second factor dealt with matriconditioning subtances, i.e without matriconditioning, sawdust, carbonized rice hull and rice straw. The results showed that matriconditioning treatments improved seed and seedling qualities of the maize seeds derived from different storage periods. Shorter seed storage period produced seedlings with higher percentage of germination, germination rate, seedling dry weight, shoots and roots lenghts and lower EC. Among the tested matriconditioning substances, carbonized rice hull provided more suitable condition to improve seedling qualities in any seed storage period than saw dust and rice straw.
