Abstract Background A need for research searching for alternative rumen enhancers warrants immediate attention. The in vitro fermentation experiment was conducted using factorial arrangement of two factors of roughage to concentrate and seven level of red amaranth leaf powder percentage of total substrate in a Completely randomized design (CRD). Two factors, namely Factor A was two ratio of roughage (R) to concentrate (C) at 60:40 and 40:60 and Factor B was level of red amaranth (Amaranthus cruentus, L) leaf powder (RALP) supplementation at 0, 2, 4, 6, 8, 10, and 12% of total dietary substrate. Results Red amaranth leaf powder (RALP) contained phytonutrients both condensed tannins and saponins in addition with high macro minerals (Ca, K, and Mg). This experiment revealed innovations of the RALP supplementation by enhancing rumen propionate (C3) production, reducing acetate (C2) to (C3) ratio, reducing protozoal population and mitigating methane (CH4) production. Furthermore, rumen dry matter degradation percentages were remarkably enhanced (P < 0.001) by increasing RALP supplementation. Conclusion Plants rich in phytonutrients and minerals such as red amaranth leaf powder (RALP) have a vital and promising role in modulating rumen fermentation, mitigating methane production, as well as increasing substrate degradability.

Summary In vitro micrografting is a technique for grafting scions to rootstocks of plantlets from tissue culture. In vitro micrografting of Cinchona plant has never been carried out. The objective of this research was to obtain the best method of in vitro micrografting, medium for micrografted plantlets, and acclimatization  for Cinchona plantlets from  micrografting. The research consisted of (i) optimization of micrografting method, (ii) optimization of medium for growing plantlets, and (iii) acclimatization of micrografted plantlet. Plantlets of four-month-old of  C. ledgeriana  QRC clone were used as  scions, while of C. succirubra as  rootstocks. Each of experiments was arranged according to Completely Randomized Design, consisted of  combination of scion and rootstock and type of micro-grafting with 10 replicates. Parameters measured were  the percentage of survived plantlet, leaf number, and callus productions on union area, and percentage of survived  plantlet. The results show that V type of micrografting was the best for Cinchona micrografting. MS medium with the addition of 3 mg/L IBA was the best medium for growing of micrografted plantlet. Husk charcoal mixed with top soil (1 : 1) was the best medium for acclimatization.  Acclimatization  consisted  of two steps: preaclimatization in a culture room with 12- hour photoperiod at temperature 25 – 27oC  for two weeks,  followed by aclimatization in a plastic house with  70% reduced light intensity for one month. Using this method, 90% of the seedlings were survived. It is concluded that in vitro micrografting can be used as a technique for clonal propagation of Cinchona sp.Ringkasan  Teknik sambung mikro (mikrografting) in vitro adalah teknik penyambungan potongan batang atas pada batang bawah dalam kultur jaringan.  Pada tanaman kina teknik sambung mikro  in vitro belum pernah dilakukan. Tujuan penelitian ini adalah  menetapkan tipe sambung mikro, medium terbaik untuk planlet hasil sambung  mikro, dan perbanyakan tanaman kina dengan sambung mikro. Pelaksanaan percobaan meliputi (i) optimasi tipe sambung, (ii) optimasi  medium, dan (iii) aklimatisasi planlet hasil sambung mikro.

In vitro rooting of micropropagated shoots were carried out with the aim of evaluating the root induction responses of two tomatoes (Lycopersicon esculentum MILL) varieties (Gelilema and Chali) using Indole -3- butyric acid (IBA). Seven levels of IBA (0.0, 0.25, 0.5, 0.75, 1.0, 1.25 and 1.5 mg L-1) were used in a completely randomized design (CRD) in factorial combinations (seven level of IBA*two varieties) with three replications.  After the plantlets were kept in the rooting media for three weeks, data on rooting percentage, number of roots/shoots and root length in cm were collected. The analysis of variance showed that the interaction of IBA*Var was highly significantly different for rooting percentage, a number of roots/shoot and root length at p<0.01. The highest rooting percentage (100.00±0.00), number of roots/shoot (14.20±0.35) and root length (10.7±0.29) were received from Chali on free Murashige and Skoog medium (MS). At the same time, the lowest percentage of rooting (11.11±0.00), number of roots/shoot (0.887±0.19) and root length (1.00±0.00 cm) were obtained from Gelilema on MS+1.5mg/l IBA. For acclimatization, the in vitro rooted shoots were transplanted into plastic pots containing a mixture of oven sterilized soil and sand at a ratio of 2:1. After three weeks, a survival rate of 67.7% for Chali and 58.1% for Gelilema was obtained. From the above result, it can be concluded that free MS medium was the best for in vitro rooting of the two tomato varieties. The optimized protocol will be useful for rapid in vitro multiplication of the two tomato varieties.

In this study, micro propagation of two Iranian fenugreek populations and their morphological and biochemical responses to salinity and drought stresses in in vitro culture condition were conducted using factorial experiment in a completely randomized design in three replications. Different explant type (terminal bud, cotyledon and epicotyledon explant) were cultured in MS medium contain different concentration of plant growth regulators such as kin (0, 0.5 and 1 mg / l) and 2,4-D (0.5, 1 and 2 mg / l). Murashige and Skoog (MS) medium supplemented with 1 mg/l kinetin and 2 mg/l 2,4-D showed the highest callus proliferation rate per explants in both populations. The highest amount of callus volume was obtained from the explants of the terminal bud. Proliferated calli from terminal bud explant were green and yellowish, from cotyledon were yellowish to white with soft texture, and the cotyledons were greenish and compact. The results of salinity stresses with different concentrations of sodium chloride (0, 70 and 120 mM) and drought stress with polyethylene glycol (0, 5 and 10%) showed that both stresses decreased callus growth and increased total protein, proline, catalase, peroxidase and trigonelin content in both populations. Trigonelin measurement showed that ‘Borazjan’ papulation had higher trigonelin content, in vitro, than ‘Ardestan’ papulation.
