The objective of this study to enhance quality for hybrid using given treatments field. experiment conducted at Department Seed Science Technology, University Agricultural Sciences, Raichur, Karnataka laboratory field condi...

A protocol was developed for high frequency in vitro multiplication of an ornamental orchid, Phalaenopsis amabilis (L.) Blume var. Jawa, using plant growth regulators (PGRs). Protocorm-like bodies (PLBs), as explants were cultured on Murashige and Skoog (MS) medium fortified with various concentrations of kinetin (KIN) and indole-3-butyric acid (IBA), either individually or in...

An efficient in vitro protocol was standardized for Almond (Prunus dulcis) propagation using dormant axillary buds as explants. Explants were cultured on Murashige and Skoog (MS) and woody plant medium (WPM) supplemented with different concentration/combination(s) of phytohormones. MS basal medium showed lowest shoot induction and took longest duration for shoot initiation. Multiple shoots were...

two experiments were performed for in vitro establishment, proliferation and shoot growth in axillary bud explants of sebri pear cultivar. in the first experiment, the effect of different concentrations of iba(indole-3-butyric acid) on explants’ establishment was evaluated. in a second experiment, the influence of several combinations of pgrs (plant growth regulators)on shoot proliferation and ...

We analyzed DNA damage, mitotic activity and polyploidization in Crepis capillaris callus cells during shortand long-term in vitro culture, and the influence of plant growth regulators on these processes. Changes in the concentration of growth regulators altered the stability of callus. The level of DNA damage was highly dependent on the growth regulator composition of the medium. Cytokinin at ...

A better understanding of the development and architecture of roots is essential to develop strategies to increase crop yield and optimize agricultural land use. Roots control nutrient and water uptake, provide anchoring and mechanical support and can serve as important storage organs. Root growth and development is under tight genetic control and modulated by developmental cues including plant...

New plant growth regulators, named citrinolactones A (1), B (2) and C (3) and sclerotinin C (4), were isolated from Penicillium citrinum and their structures established by spectroscopic methods including 2D NMR. Compounds 1 and 4 increased root growth in proportion to their concentration from 3 to 300 mg/l. In contrast, 2 completely inhibited root growth at a concentration of 300 mg/l and 3 di...

to study the effect of some varying treatments including such environmental factors as temperature, moisture, and light as well as plant growth regulators on breaking dormancy of datura stramonium l. seeds, several experiments were conducted. seeds of datura stramonium l. possess full dormancy immediately following harvest. storing the seeds for 3 months (15 dec. 2005 to 15 march 2006) at room ...

Background: Stevia rebaudiana Bertoni, an important anti-diabetic medicinal plant, becomes an inevitable alternative to sugar. Due to the propagation difficulties, tissue culture is the best alternative for rapid mass propagation of stevia plants. Objective: The present study was conducted to optimize a protocol for rapid micropropagation of Stevia rebaudiana by shoot tip explants and to inv...
