Ziziphus Jujuba

The Chinese jujube (Ziziphus jujuba Mill.), originating from China, with a history of over 4000 years, is one of the major fruit crops cultivated in China and on important areas in Central Asia, India, Iran, the Middle East etc. The high resistances to drought, salty soils and similar climate to that of China recommend this fruit tree as a valuable crop, especially in the context of climate changes and extended desertification. Chinese jujube has a high tolerance to pests and disease, being suitable for organic farming. The lack of divulgative papers on jujube true nutritional, medicinal and economic value, makes it still unknown for the great part of Romanian and European consumers, intensive advertising campaign is needed. The aim of this review is to highlight the requirements of the Chinese jujube (Ziziphus jujuba Mill.) in regards to the soil, water, climate as well as its high nutritional and medicinal values.

In Vitro Shoot Regeneration

A shoot regeneration system for Plectranthus neochilus was studied from leaf explants. Leaves developed under in vitro conditions were cultured on Wood Plant Medium supplemented with 0.2mg dm-3 α-naphthaleneacetic acid (NAA) and different 6-benzilaminopurine (BAP) or thidiazuron (TDZ) concentrations (0, 1.5, 3.0, 4.5 and 6.0mg dm-3). An increase in percentage of responsive explants (85.3%) and in the number of shoots developed per explant (3.2) was observed when the explants were treated with 5.3 and 4.7mg dm-3 BAP, respectively. The leaf explants cultured on media supplemented with TDZ became vitreous and did not form buds. The regeneration system used is efficient for boldo bud induction and shoot development, showing high potential for advanced cellular and molecular studies.

The tissue culture regeneration system of Lupinus albus has always been considered as recalcitrant material due to its genotype-dependent response and low regeneration efficiency that hamper the use of genetic engineering. Establishment of repeatable plant regeneration protocol is a prerequisite tool for successful application of genetic engineering. This aim of this study was to develop standardized, efficient protocol for successful shoot induction from cotyledonary node of white lupin. In this study, 5 day old aseptically cultured seedlings were used to prepare three explants (half cotyledonary node, HCN; whole cotyledonary node, WCN; and traditional cotyledonary node, TCN), cultured on four concentrations of M519 medium (M519, ½ M519, 1/3 M519, and ¼ M519), containing four carbohydrate sources (sucrose, fructose, maltose, and glucose), and stimulated with various combinations of KT (kinetin), and NAA (naphthalene acetic acid) for direct shoot regeneration. High frequency of 80% shoot regeneration was obtained on ½ M519 medium (KT 4.0 mg L−1 + NAA 0.1 mg L−1) by using HCN as an explant. Interestingly, combinations of (KT 4.0 mg L−1 + NAA 0.1 mg L−1 + BAP 1.67 mg L−1), and (KT 2.0 mg L−1 + NAA 0.1 mg L−1) showed similar shoot regeneration frequency of 60%. Augmentation of 0.25 g L−1 activated charcoal (AC) not only reduced browning effect but also improved shoot elongation. Among the all carbohydrate sources, sucrose showed the highest regeneration frequency with HCN. Additionally, 80% rooting frequency was recorded on ½ M519 containing IAA 1.0 mg L−1 + KT 0.1 mg L−1 (indole acetic acid) after 28 days of culturing. The present study describes establishment of an efficient and successful protocol for direct plant regeneration of white lupin from different cotyledonary nodes.
