“…The density of glandular trichomes on Tectona grandis L. in vitro leaves and on S. officinalis ex vitro and in vitro leaves increases with the physiological age of the plant (Bandyopadhyay et al 2004;Avato et al 2005). Also, Bandyopadhyay et al (2004) reported a significant positive Plant Cell Tiss Organ Cult (2010) 101:183-191 189 correlation between water and phenol percentages and leaf area covered with trichomes in T. grandis.…”

The anatomy of normal and hyperhydric shoots (leaves and stems) of in vitro Handroanthus impetiginosus was compared using light microscopy, scanning electron microscopy, and transmission electron microscopy. In contrast to normal shoots, hyperhydric shoots presented numerous anatomical abnormalities at the proliferation stage. Disorganized cortex, epidermal holes, epidermal discontinuity, collapsed cells, and other structural characteristics were observed in hyperhydric shoots. So, by using anatomical analysis of in vitro H. impetiginosus shoots at the proliferation stage, we can predict which plants will survive the rhizogenesis and acclimatization stages.

“…Green chayotes had a lower frequency of trichomes, mainly XB and SG, followed by CB, W, and PG (Table 4). Trichomes help to reflect the excess of visible and infrared light, creating energy balance in the leaf (Manetas 2003;Bandyopadhyay et al 2004). These trichomes increase the resistance of the border layer, maintaining a humid micro-environment on the surface reducing the transpirational losses of water, and thus, maintain the leaf temperature more stable (Agren and Shemske 1994).…”

In this study a morphological and anatomical variation analysis was carried out with leaves and fruits of Sechium edule, collected in the central region of Veracruz, Mexico. The collected fruits were classified in eight groups according to their typical characteristics. The results showed that the phenotypical distinction of the studied infraspecific S. edule complex is related to morphological and anatomical changes in order to improve the adaptive specialization of the different chayote types with respect to the environment, and suggests that cultivated chayotes have followed different routes in the process of coevolution with man, showing stable variation patterns in the so-called ''green'' and ''yellow'' groups. Considering the phenotypic variability existing in the analyzed characters, a certain prediction may be proposed about the direction the variation patterns may follow facing the transference of chayotes to environments of lower altitudes than mountain cloud forest.

“…As a result, they had an inefficient management of water and were consequently more susceptible to dehydration and they did not survive during acclimatization. In accordance with Bandyopadhyay et al 2004, water is the most important component of plants and inefficient management of it may lead to poor rate of hardening and transplantation. On the other hand, we showed in our experiments that the in vitro conditions prior to acclimatization were important for the ex-vitro growth of the micropropagated teak plants, which is consistent with other authors" results with different species (Kadleček et al 2001, Hazarika, 2006, Mocaleán et al 2009).…”

“…In teak, phenolics have been associated to a defence mechanism against dehydration and pathogen attack. The in vitro teak leaves are covered with particular globose trichomes, appearing to be glandular ones contained phenol droplets within them (Bandyopadhyay et al 2004). …”

In vitro shoot proliferation of Tectona grandis L. (teak) using temporary immersion system (TIS) and different concentrations of BA is presented. Shoots grown on semi-solid MS medium supplemented with 2% (w/v) sucrose and 4.44 µM of BA were used as starting materials. In the TIS, three BA concentrations (2.22, 4.44 and 6.66 µM) and a cytokinin-free medium (CK-free medium) were assayed. A high average number of shoot was reached, applying 4.44 and 6.66 µM of BA (7.7 and 10.3 shoots/explant), respectively. The high BA concentrations decreased the accumulation of phenolic compounds and the deposition of lignin in the vascular cells of the teak shoots. The morphometric analysis by scanning microscopy revealed that the leaves of the shoots cultured in the TIS in Ck-free medium and with 2.22 and 4.44 µM of BA showed elliptical stomata; however, in the leaves developed with 6.66 µM of BA, the stomata were majorly ring-shaped, raised and wide open. Deformed stomata with broken epidermis of the guard cells, typical of hyperhydric leaves, were also observed. The survival percentages after ex vitro rooting on the IBA (492.1 µM) solution were higher in plantlets from CK-free medium and with 2.22 µM of BA, (96.7 and 91.7%, respectively) than those cultured on semi-solid medium (73%). The shoots from both TIS treatments developed a good root system. Plantlets from 6.66 µM of BA showed the lowest survival percentages (60%). A survival percentage was 100% two weeks after transplanting, and three months after ex vitro transfer, the plants were ready for field plantation. Here we present the first report of the successful propagation of teak by TIS.
