Abstract Plant propagation through in vitro culture is increasingly being used to produce hybrid orchids. Plant tissue culture provides a good alternative to produce plants in large numbers in a short time. The provision of organic growth supplements in tissue culture media plays an important role as a substitute for growth regulators in stimulating the growth of explants. In this study, young coconut water, banana extract (cv. ambon), and tomato extract were used to stimulate the growth of the Vanda tricolor Lindl. Var suavis protocorm. Data were analyzed using a completely randomized design (CRD) with five replications using the Kruskal-Wallis test and continued with the Mann-Whitney test if there was a significant difference between each treatment and its concentration. Parameters observed were the percentage of the number of shoots and the number of leaves. The results showed that there was a significant difference between the treatments given to the number of leaves. Mann-Whitney further test results on the number of leaves showed a significant difference in the banana extract treatment and the control treatment.

ABSTRACT: The objective of this paper was to evaluate the effects of different honey concentrations in culture media, in comparison to sucrose medium, for the in vitro development of the epiphytic Encyclea cordigera orchid, in order to improve the process of propagation of the species. The in vitro germination was prepared on a reduced Murashige & Skoog (MS) medium. After 90 days, the seedlings were divided into different treatments, where they remained for another 90 days. Six treatments were set up (30g L-1 of sucrose; 15, 30, 45, and 60g L-1 of honey; and absence of any carbohydrates) in a completely randomized design. Plants were removed from the vials 270 days after the start of the experiment, and the number of roots, length of the largest leaf, length of the longest root, number of leaves, and fresh and dry masses were evaluated. Data concerning the number of leaves and roots were (x+1)1/2 transformed and subjected to an analysis of variance (ANOVA); the means were compared by a Tukey's test set at 5% probability. Medium containing 60g L-1 of honey proved to be superior to the sucrose medium traditionally used, favoring the in vitro growth and development of Encyclea cordigera. This medium can therefore be recommended for the propagation of this species, which is usually cultivated as an ornamental plant.

In vitro dendrobium orchid plantlet growth is highly determined by the cytokinin and auxin concentration. The aim of this research was to study the effect of 6-Benzylaminopurine (BAP) and Naphthaeeneacetic Acid (NAA) on growth of Dendrobium orchid plantlet. The research was arranged in completely randomized design (CRD) with two treatments. The first treatment was the concentration of BAP (A1 : 0 ppm, A2 : 1 ppm, A3 : 2 ppm) and the second treatment was the concentration of NAA (B0 : 0 ppm, B1 : 0,25 ppm, B2 : 0,50 ppm) with 4 replications. The observed variables were number of buds, plantlet height, number of leaves, and length of leaves. The data obtained were analyzed by Analysis of Variance and followed by Least Significance Different (LSD). The result showed that treatment of BAP and NAA only significantly affected the number of buds variable. The combination of BAP 1 ppm and NAA 0,25 ppm was the best treatment for increasing number of buds of dendrobium orchid plantlet.

Double-node microshoots of bigtooth maple (Acer grandidentatum Nutt.) were rooted in vitro on Driver-Kuniyuki Walnut (DKW) tissue culture media containing indole acetic acid (IAA). Microshoots represented six sources from three locations within Texas and New Mexico. Microshoots were placed in Phytatrays II™ containing DKW media with no plant growth regulator (DKW0) to reduce the high cytokinin levels used for shoot proliferation. Microshoots were induced to form roots for 15 days by placing them on DKW media containing IAA at 0.01, 1, 2.5, 5, 10, 15 or 20 μmol. Rooting frequency, the number of leaves and callus area were recorded every 30 days for 60 days. Rooting frequency increased up to 29% as IAA concentration increased (P= 0.004). However, as much as 71% of shoots for one of the three Guadalupe Mountain, Texas, sources rooted without auxin treatment after 30 days. The IAA concentration also affected the number of leaves per shoot (P= 0.0228) which averaged seven and callus area (P= <0.0001) which averaged 52 mm2. Average leaf size was 307 mm2. We conclude that IAA induces rooting in microshoots of bigtooth maple after 15 days of root induction. However, one source rooted without auxin treatment. The presence of callus does not interfere with root formation.

To investigate the suitable medium for in vitro shoot regeneration and plantlet growth of Dendrobium crumenatum Sw., individual protocorm-like bodies (PLBs) (about 4 - 5 mm in diameter) of Dendrobium crumenatum Sw. derived from MS medium supplemented with 0.5 mg/L TDZ for 60 days of culture were cultured on 6 culture media; Murashige and Skoog (MS) medium, MS medium supplemented with 15 % (v/v) CW, MS medium supplemented with 15 % (v/v) CW and 0.2 % (w/v) AC, Vacin and Went (VW) medium, VW medium supplemented with 15 % (v/v) CW, VW medium supplemented with 15 % (v/v) CW and 0.2 % (w/v) AC. After 4 months of culture, MS medium containing 15 % coconut water (CW) gave the highest percentage of shooting and number of shoots per explant of 96.0 and 9.5, respectively with a significant difference from other media. The addition of 0.2 % (w/v) activated charcoal (AC) significantly increased the number of leaves and roots. PLBs developed into complete plantlets. MS medium supplemented with 15 % (v/v) CW and 0.2 % (w/v) AC and VW medium supplemented with 15 % (v/v) CW and 0.2 % (w/v) AC gave the highest number of roots per plantlet and root length at 5.3 roots and 34.9 mm, respectively. After the transfer of rooted shoots to the greenhouse, 95 % of the regenerated plantlets survived and grew vigorously. Plantlets grown in vitro were successfully acclimatized in the greenhouse and showed normal development.
