Embelia ribes, commonly known as Vidanga or false pepper is a commercially important threatened medicinal plant of the Tropics belonging to the family Myrsinaceae which yields embelin, a highly valuable quinine derivative. Regeneration of the crop is poor due to over exploitation, diminishing forest area, dormant seeds, abortive embryos and hard seed coat. Seeds were subjected to several pre-soaking treatments i.e, soaking in water, aqueous solutions of GA3 at different concentrations, acid scarification using HCl, H2 SO4 and combination of acid scarification and GA3. Seeds treated with GA3 750 ppm for 24 hours and H2SO4 scarified seeds treated with GA3 750 ppm for 12 hours exhibited superior results compared to the untreated control. The shoot length (8.82 cm), root length (8.03 cm), and total dry biomass (70.21mg) were maximum in seeds treated with GA3 750 ppm whereas, germination percentage (87.5) and seedling vigour (1410.42) were maximum in H2SO4 scarified seeds treated with with GA3 750 ppm.

Effect of chemicals on seed germination and seedling growth of Aonla (Emblica officinalis Gaertn.)
2020
The experiment entitled “Effect of chemicals on seed germination and seedling growth of Aonla (Emblica officinalis Gaertn.)” was carried out at Regional Horticultural Research Station (RHRS), ASPEE College of Horticulture and Forestry, Navsari Agricultural University, Navsari during 2019-20. The experiment consisted 11 treatments viz. control (T1), water soaking (T2), thiourea @ 0.5 % (T3), thiourea @ 1.0 % (T4), thiourea @ 1.5 % (T5), KNO3 @ 0.5 % (T6), KNO3 @ 1.0 % (T7), KNO3 @ 1.5 (T8), GA3 @ 250 mg/l (T9), GA3 @ 500 mg/l (T10) and GA3 @ 750 mg/l (T11). The seeds of aonla were soaked with these chemicals for 24 hours and sown in polybags. The experiment was carried out in completely randomized design and repeated thrice. The effect of different treatments on germination, seedling growth and survival percentage were recorded. The results of experiment showed that aonla seeds treated with GA3 @ 500 mg/l (T10) gave the highest germination percentage (67.89) along with early emergenc...
Ethnopharmacological Uses of Embelia ribes Burm. F. -A Review
Embelia ribes Burm.f. is a threatened medicinal plant, studied extensively for its rich medicinal properties. It has been used in ayurvedic formulations from the ancient times and in the recent past a surge of research on this particular medicinal plant species has been undertaken. This particular species is found to attribute to a number of medicinal properties such as antidiabetic, anticancer, antimicrobial, antitumor, antifertility activity and many more. Hence this highly comprehensive review has been under taken to highlight the areas of research where in this particular species is extensively studied and the current status of this important threatened medicinal plant.

Emblica officinalis Gaertn. is an important non-timber forest product plant which is known in improving livelihood of the people of north-east India. This plant is widely used in the Indian system of medicines and believed to increase the body immunity against diseases. A trial was made to assess the initial growth performance of seedlings of E. officinalis under three light regimes viz. Open-100% ambient sunlight (FAL), partial-80% ambient sunlight (PAL) and deep shade-40% ambient sunlight (DAL) and four nutrient conditions (NPK, saw dust biochar, cowdung and untreated) during a 3-months period in the Department of Forestry Mizoram University, Mizoram India. After 12 weeks of exposure to different light regimes and nutrient conditions, initial growth parameters of the seedlings like number of leaves, shoot length, root length, biomass and vigour index measured in order to understand the best growth conditions for the plant. The results reveal that seed germination and other growth ...
Study on Seed dormancy and Seed Germination Procedures in Some Medicinal Plant Species
The study was conducted to find out the requirements for seed germination in medicinal plant species v iz. Ashwagandha (Withania somanifera), Sabja (Ocimum pallens), Dawana (Artenisia Pallens), Sonamukhi (Cassia angustifolia) and Wild brinjal (Solanum viarum). The seeds of the above species may be germinated on top of paper(TP) except Ashwagandha, which germinated better in between paper (BP) method. Maximum germination (92%) could be obtained at 20 o C in Ashwagandha seeds while seeds of Dawana showed maximum germination at 30 o C. The seeds of Sonamukhi, Sabja and Wild brinjal showed poor germination due to dormancy. The soaking of seeds in water for 24 h and germinating at 20 o C gave maximum germination in Sonamukhi. The treatment of Seeds with 25% Nitric acid for 10 min. and germination at 30 o C was found ideal for Sabja. For wild brinjal treatment of 12.5% Nitric acid for 15 min. followed by 1000 ppm GA3 for 24 h with alternate temperature of 20-30 is recommended.

Background: Vidang (Embelia ribes Burm.f.) is a very genuine plant for its anthelmintic activity. In Ayurveda, it is a first choice of drug for its krimighna action or to kill foreign pathogens. Embelia robusta auct. Non roxb., the other species of vidang is adulterated in Embelia ribes Burm.f. Objective: Preliminary pharmacognostical study includes macroscopic & microscopic characteristics which are also a tool for identification & authentication of a plant. Therefore shastrokta or original vidang & its adulterant species were selected for the comparative study. Materials & Methods: For macroscopic study, dried fruits were observed with all sense organs. For microscopic study, dried fruits were made softened with water & dilute Hydrochloride acid. Then transverse sections were cut & then observed in binocular microscope. Results: Embelia ribes Burm.f. is black in colour. A few yellow spots are present on its seed. Embelia robusta auct.Non roxb. is reddish brown in colour. Its seed ...

The experiments were led to study the effect of pretreatments (concentrated sulphuric acid and gibberellic acid) on germination behavior of Malus baccata by analyzing three parameters i.e. GP: germination percentage, MGT: mean germination time (days) and GRI: germination rate index for various time interval in petridishes. Pre-sowing treatment included immersion in sulphuric acid (98%) for 10, 20 and 30 minutes and immersion in gibberellic acid of 1000, 1250 and 1500 ppm for 24 hrs. The sowing in distilled water (Control) had no positive effect on the germination induction. Generally, the seed pretreatments with sulphuric acid (98%) were very useful to improve germination. Time of immersion significantly (P < 0.001) affected GP, MGT and GRI. Treating Malus baccata seeds with sulphuric acid (98%) for 10, 20 and 30 minutes significantly broke the seed dormancy and promoted the germination of the seeds compared to control seeds (treated with distilled water) and gibberellic acid.
