“…Variability in root anatomy results mainly from the different origins of the cambium and its different products (Carlquist, 2001;Islam et al, 2007;Kraus and Basconsuelo, 2009;Kraus et al, 2003;Kraus et al, 2007;Metcalfe and Chalk, 1983;Rajput et al, 2006;Rajput, 2003). In the species belonging to the tribes Aeschynomeneae, Vicieae, and Trifolieae, the cambium results from a procambial remnant located between the xylem and the phloem.…”

“…Previous studies on legumes have demonstrated not only the diversity in the origin of the cambium (Carlquist, 2001;Metcalfe and Chalk, 1983) but also the occurrence of different cambial types, ranging from normal to more complex ones (Basconsuelo, 2004;Islam et al, 2007;Kraus and Basconsuelo, 2009;Kraus et al, 2003;Kraus et al, 2007;Kutschera and Lichtenegger, 1992;Lachaud et al, 1999;Milanez and Moraes-Dallaqua, 2003;Pate et al, 1989;Rajput et al, 2006;Rajput, 2003). In general, the majority of studies on legumes relate root anatomy to the environment rather than to systematics.…”

“…Earlier works have described the occurrence of successive cambia in the form of interand intraxylary phloem, a characteristic feature of the family Convolvulaceae. Initiation of small segments of inverse cambia has been reported in Dolichos lablab L. and in other species of Ipomoea L. (Rajput et al 2006(Rajput et al , 2008Terrazas et al 2011). Patil et al (2009) and Terrazas et al (2011) observed the origin of internal cambium at the pith margin and the development of intraxylary phloem from the pith margin in other species of Ipomoea.…”

Abstract. Structural transformation of mechanical tissues during the shift from a freestanding to a climbing habit is a characteristic of lianas, which are increasingly abundant in tropical forests. The modification of mechanical tissue and the evolution of a new growth pattern serve to increase stem flexibility and conductive efficiency. In Ipomoea turbinata Lag. (Convolvulaceae), the stem thickens via the formation of two distinct types of successive cambia: functionally normal successive cambia (producing xylem centripetally and phloem centrifugally), and inverse cambia (producing xylem centrifugally and phloem centripetally). The former originates from pericyclic derivatives (parenchyma cells located outside the primary phloem), while the latter originates from the conjunctive parenchyma located on the inner margin of the secondary xylem formed from vascular cambium. The secondary xylem produced by normal cambia is significantly more abundant than the xylem formed by inverse cambia. During primary growth, intraxylary primary phloem differentiates concomitantly with the protoxylem at the periphery of the pith; additional intraxylary secondary phloem is added from adjacent parenchyma cells as the plant ages. During initiation of every successive cambium, middle cells in the meristem give rise to cambium, and cells on either side of it serve as sites for initiation of future cambia. The functional role of inverse cambia remains unknown and awaits further experimental studies.

Penelitian yang khusus mengkaji tentang struktur anatomi kacang komak dilakukan oleh Rajput (2006), yang mengkaji struktur batang anatomi kacang komak yang tumbuh di India. Penelitian tersebut menemukan bahwa struktur anatomi batang kacang komak menunjukkan anomali kambium atau yang dikenal sebagai cambial variant adalah hal asal usul jaringan kambiumnya.…”

“…Penelitian ini menggunakan batang tanaman komak yang usianya kurang dari 1 tahun sehingga anomali kambium tidak ditemukan. Rajput, et al (2006), menyatakan bahwa anomali kambium pada genus Lablab akan ditemukan ketika batang sudah berusia 3 tahun. Anomali tersebut berupa adanya susunan/orientasi terbalik pada berkas pengangkut pada batang.…”

Hyacinth bean (Lablab purpureus (L.) Sweet) is a member of Fabaceae which has high economic potential but is still treated as an underutilized crop. Research on Lombok's hyacinth bean focused on stem anatomical profile has never been conducted. The aims of this research were to study stem anatomical profile of hyacinth bean in Lombok, West Nusa Tenggara. Young and mature stem were collected using exploration method. Anatomical sample preparation was done using free hand section method, stained with safranin, and mounted in a glycerine liquid. Sample was visualized and documented using binocular microscope connected to the digital camera integrated with ScopeImage 9 software. Data were analyzed by a triangulation method. The result showed that stem anatomical profile of hyacinth bean in Lombok by transversal section consists of one layer of an epidermal cell and unicellular glandular trichomes as it's derivate. Parenchyma cell was found in the cortex, interfascicular region, and pith in shape of rounded, oval, up to polygonal and varied in size. Vascular tissue showed a unique structure and became the distinctive feature od hyacinth bean stem. There were 2 type of vascular bundles i.e big and small vascular bundles. The large vascular bundles contain xylem and phloem and the small vascular bundles may or may not contain both xylem and phloem.
