Abstract

Jackfruit seeds are recalcitrant and hence desiccation sensitive. Fresh jackfruit seeds were subjected to desiccation by exposing to air drying at room temperature (30±2ºC). During desiccation the seeds retained viability only up to 12 days. Histological and histochemical changes during desiccation up to the loss of viability were studied at comparable intervals during a period of 16 days. Disappearance of starch grains was observed in the cotyledons and the tip of the embryonic axis during desiccation. The distribution of starch grains in the cotyledons and embryonic axis and the histological changes in the embryonic axes were found to be directly related to the loss of seed viability.

Abstract

In order to study the desiccation sensitivity and water relations pertaining to recalcitrant behaviour of jackfruit seeds which contain very high MC (50%), the seeds were stored in different storage conditions like room-open (30±2°C), room-polythene (30±2°C) and refrigerator (4-8°C). The moisture content and germination percentage were determined at regular intervals of storage. During open air storage, these seeds remained viable only for 12 days and the moisture content was decreased resultantly the viability was lost when the MC reached below a critical level (32%). Room-polythene storage was found to be more effective since the seeds remained viable for about four months. In refrigerator-storage also viability was retained up to about four months. The data confirmed the recalcitrant nature of jackfruit seeds and interpreted in terms of distribution of moisture content superimposed with viability loss and metabolic changes that occur during storage.

Abstract

Free radical scavenging potential of leaves of Memecylon edule. Roxb was studied using superoxide radical scavenging effect, hydroxyl radical scavenging effect, lipid peroxide assay, nitric oxide scavenging effect. The content of superoxide radicals was studied by NBT reduction method, hydroxyl radical by Deoxy-ribose degradation method, lipid peroxide level by estimating the thiobarbituric acid releasing substances (TBARS) and the nitric oxide radical by Griess method. The ethanolic and aqueous leaf extracts were used for the study with reference to the ascorbic acid as standard drug. It was found that the aqueous extract showed significant free radical scavenging potential compared to the ethanolic extract. The IC₅₀ for aqueous extract was found to be 502.9μg/ml, 493.78μg/ml, 469.6μg/ml and 227.8 μg/ml for superoxide radical scavenging effect, hydroxyl radical scavenging effect, lipid peroxide assay and nitric oxide scavenging effect respectively. The extracts studied can provide efficient antioxidant protection by complementary mechanisms, such as free radical scavenging and metal ions reduction with the non polar extracts.

Abstract

The genus Podagrion was erected by Spinola (1811) from Caucasia based on the type species Podagrion splendens Spinola. Later several authors like Walker (1833), Westwood (1847), Costa (1856), Holmgren (1869), Saussure (1890), Schulz (1906), Girault (1913) and Gahan and Fagan (1923) redescribed or treated it under various junior synonyms. In the recent past Narendran (1994) revised the Indian species of Podagrion and gave a key to species in his revision of Torymidae and Eurytomidae of Indian subcontinent. Grissell (1995) treated Podagrion in his world revision of Toryminae.
