    Opis:
    Pretreatment of seeds of seven wild plant taxa (viz., Gaultheria hookeri C. B. Clarke, G. stapfiana Airy Shaw, G. semi-infera (C. B. Clarke) Airy Shaw, G. trichophylla Royle var. ovata Panda & Sanjappa, Lyonia ovalifolia (Wall.) Drude var. ovalifolia, Pieris formosa (Wall.) D. Don and Vaccinium glauco-album C. B. Clarke) in the family Ericaceae using Na-dikegulac (Na-DK) for 8 hours (4 + 4 h in two installments) before keeping in ambient storage condition (32±2 ºC) for different durations (0 and 20 days) slowed down the rapid loss of germination and reduced the time (h) required for 50% seed germination (T50). Concomitantly, the reduction of protein level as well as the activity of catalase of seed kernels during storage period was ameliorated to a significant extent in the chemical pretreated seed lots.

    Opis:
    Pretreatment of mungbean (Vigna radiata) seeds with leaf extract of tulsi (Ocimum sanctum) for 4 hours before accelerated ageing treatment (99.5% RH and 32±2oC) for different durations for 30 days slowed down the ageing-induced rapid loss of seed germination. Plant performance was found to be much better developed from seeds which underwent plant extract pretreatment measured in terms of few reliable indices. Plant potential was also higher in the pretreatment as evidenced from the treatment-induced higher chlorophyll level as well as activity of catalase enzyme. Results, therefore, pointed out that the plant extract-pretreated seeds retained higher seed vigour and produced healthier plants inspite of experiencing accelerated ageing treatment.

    Opis:
    Keeping in mind the problem of seed storing in tropical and subtropical countries where high temperature and high relative humidity (RH) greatly accelerate seed ageing phenomenon causing consequent deterioration and non-viability of seeds, an investigation was carried out on maintenance of storage potentiation of a green gram species by using selected plant extract. Pretreatment of green gram (Phaseolous mungo L.) seeds with aqueous solution of leaf extract of neem (Melia azadarch) 50g in 500 ml distilled water for 2 hours and then dried back to the original dry weight of the seeds before accelerated ageing treatment (99.1% RH and 32±2 ºC) for different durations (0 to 30 days) slowed down the rapid loss of germination and reduced the time (h) required for 50% seed germination (T50) of the seeds. The plant extract also significantly arrested the reduction of protein, insoluble carbohydrate, DNA and RNA levels as well as activity of catalase enzyme of seed kernels during forced ageing period. Ageing-induced stimulation of the activity of amylase enzyme was also alleviated by the seed pretreating agent.

    Leaf senescence
    Opis:
    Efficacy of a growth promoter ascorbic acid (Vitamin C) on senescence deferral action was analysed using leaf discs of six wild ericoid plant taxa. Changes of some biochemical parameters like chlorophyll, protein, soluble and insoluble carbohydrates, RNA and DNA as well as activity of catalase enzyme were analysed as reliable senescence indices during detached leaf senescence of these six species under dark condition. With the progress of ageing duration from zero to 144 hours the levels of chlorophyll and proteins in leaf discs gradually declined in both control and ascorbic acid treated samples. However, in the chemical / Vitamin-C treated samples the rate of decline was found to be much slower. Concomitantly the levels of insoluble carbohydrate, RNA and DNA started declining right from 48, 96 and 144 hours of observation period both in treated and untreated samples. And here also ascorbic acid arrested the rapid rate of reduction of the levels of the biochemical parameters. On the other hand, soluble carbohydrate level started increasing irrespective of the treatments during the whole observation periods. However, the magnitude of increase was found to be low in case of the leaf samples which experienced treatment with ascorbic acid. The activity of the enzyme catalase was found to decrease progressively during the four observation periods (0, 48, 96 and 144 hours) regardless of the treatments. Ascorbic acid partially averted the rapid fall of the enzyme activity during the ageing periods. Ascorbic acid, a nonconventional senescence deferred thus seems to be a potent senescence deferral phytohormone /chemical / vitamin at least in case of six ericoid wild plant taxa.
