Half Strength

The best response toward direct regeneration of multiple shoots from seven-dayold seedling was observed on half-strength MS supplemented with 0.5 mg/l BA. Hypocotyl and cotyledon explants produced highest percentage (73 and 66, respectively) of shoots. The maximum number of shoots (12) and the highest shoot length of 5.9 cm were also observed in this medium. On the other hand, indirect regeneration via callus was observed in cotyledonary explants. Maximum percentage of callus formation was observed on MS containing 1.0 mg/l 2,4-D and 0.5 mg/l NAA. Highest frequency of shoot regeneration was achieved on MS fortified with 2.0 mg/l BA and 0.1 mg/l NAA in cotyledon derived callus. Shoot regeneration was not obtained in hypocotyl-derived callus. Shoots rooted well when they were excised individually and implanted in halfstrength MS with 0.5 mg/l IBA in which 98% rooting was achieved within 10 - 12 days. The well rooted in vitro raised plantlets were successfully transferred to soil and their survival rate under natural environment was 86%. Key words: In vitro regeneration, Cabbage, Hypocotyl, Cotyledon  D.O.I. 10.3329/ptcb.v17i2.3233  Plant Tissue Cult. & Biotech. 17(2): 131-136, 2007 (December)

Date seeds (Phoenix dectylifera) are one of the seeds that is not usable and always end to be disposed. The present study describes date seeds as an additive on callus induction in vitro from hypocotyl explants of Vigna radiata. The objective is to explore the usage of date seed powder as growth additive to promote in plant tissue culture media thereby it can be utilized as fertilizer in vivo for sustainable agriculture. 1% concentrations of date seed powder under controlled conditions highly influenced the callus induction. MS media supplied with different auxins is prepared for callus induction. The highest degree of callus weight was observed in MS media supplemented with (5mg/L) 2, 4-D + (0.5 mg/L) Kn (0.437±0.1). MS media supplied with different concentrations of date seed powder + (5mg/L) 2,4-D + (0.5 mg/L) Kn are prepared for callus induction under controlled conditions (16hrs light and 8hrs dark, 3000 lux light intensity,60% humidity and 25±20c) in a plant growth chamber.  MS media supplied with 1% date seed + 3% sucrose + 0.5 mg/l of Kn +5 mg/l of 2,4D gave the highest stimulation of callus growth. Results show that date seed is not replacing sucrose as a carbon source, but it acts as a good additive to promote induction callus. Quantitative nutritional analysis of date seed powder was carried out. The results show date seed powder contains a high amount of elements like: Ca (2994.33), k (1712.33), Si (456.33), Mg (687.33), which plays a major role in callus formation.

Currently, a real challenge for the workers in the agricultural research field is to stop or reduce the use of expensive agrochemicals/ chemical fertilizers which are hazardous to the environment as well as human health. Present study was aimed to improve the growth and obtain optimum yield of Vigna crop with eco-friendly, non-toxic way and to reduce the use of agrochemical/chemical fertilizer application in agricultural activities. A pot experiment was conducted to study the effect of chemical fertilizer (DAP) and biofertilizer ( Rhizobium strain) separately and in combination on seed germination and seedling growth (at 30 days) based on morphological parameters such as seedling length (cm), fresh weight (g), dry weight (g) and leaf area (cm)2 of Vigna radiata (L.) Wilczek. After one month (30 Days) observations, it was found that seedling length, fresh and dry weights and leaf area were maximum in T4 and minimum in T15, T7 and T8 favored improved seedling length and leaf area whereas T7, T8, and T9 favored improved fresh and dry weights as compared to control.
