Abstract The green bean (Phaseolus vulgaris L.) is a very widely grown food crop that contributes significantly to human dietary needs in many countries due to its high content of protein. This study evaluates foliar applications of ZnSO4 versus that of zinc oxide nanoparticles (ZnO NPs) to leaves of the green bean cv. ‘Strike’ and records the plant responses in terms of Zn uptake and concentrations of photosynthetic pigments and bioactive compounds. The experiment was conducted under greenhouse conditions in Chihuahua, Mexico, with a completely randomised experimental design with 10 replicates. The two treatments were foliar applications of either an aqueous solution of ZnSO4 or an aqueous suspension of ZnO NPs (both 150 mg · L−1). The application of ZnO NPs significantly increased concentrations of Zn2+ in the leaflets, roots, stems and pods of chlorophylls a and b (values 15.40 μg · g−1 and 11.64 μg · g−1, respectively). Sucrose concentration was also increased by Zn2+ applications, but no differences were found in total phenols (TP), total flavonoids (TFl) or antioxidant capacity (AC). In the pods and seeds, Zn2+ application left sucrose and TFl concentrations unchanged, but the TP increase was significant. The AC was affected by both zinc sources and only in the pods. The applications of ZnSO4 or ZnO NPs significantly increased the biomass accumulation (79.10 g · p−1 and 84.70 g · p−1 DW) and yield (55.64 g · p−1 and 53.80 g · p−1 FW). These results suggest that the application of ZnO NPs could represent a worthwhile biofortification strategy in the commercial production of green bean cv. ‘Strike’.

Drought stress reduces photosynthetic rate and leading to depletion of the energy source and lowers the yield. Under drought stress, reduced turgor pressure cause inhibition of cell elongation and impaired mitosis leads to reduction in growth rate. Role of sucrose metabolism under drought adaptation and response of plants to stress in different tissues and at different developmental stages. Cytoplasmic sucrose synthesis is more under drought condition and there is differential expression in tolerant and susceptible cultivars. Under drought condition, plant start consuming its own sink for its survival thus reducing sucrose concentration. But reduction in sucrose concentration is less in drought tolerant plants. Drought stress induced an increase of the root/shoot ratio, which was due to the increased inhibition of biomass accumulation of shoots compared to roots. Drought stress enhanced the activities of sucrose metabolic enzymes and up-regulated the expression of genes such as SPS, SuSy and INV. In addition, drought stress up-regulated the expression levels of SWEET and SUC and promoted the transport of sucrose from source to sink.

One of the most significant challenges humanity will face is food production. In order to preserve the output, mineral fertilizers are essential. However, it's not a suitable option in the long term. Magnesium is a crucial macronutrient, but it is the most limiting element in agriculture. Nanotechnology, with the implementation of nanofertilizers, is an excellent alternative since it provides nutrients, supports growth, and improves production; this in low amounts is more sustainable than conventional fertilizers. Although there is a piece of limited information regarding the proper foliar application of this macronutrient, the study helped to validate the effect of the foliar application of Magnesium nano fertilizer on the physiological, biochemical responses and yield of bean plants. Bean plants ejotero cv. ‘Strike’ and magnesium nanoparticles were applied at doses of 0, 50, 100, and 200 ppm. The biomass accumulation, yield, activity of the enzyme nitrate reductase, and photosynthetic pigments were evaluated. The foliar application of Mg nanoparticles at 50 ppm generated the highest amount of biomass and photosynthetic pigments. The 100 ppm dose improved pods yield and allowed the increased activity of the Nitrate Reductase enzyme. The results obtained suggest that, when increasing the dose of magnesium in plants, the amount of carotenes decreases.

KAJIAN ETHYLENE TRIPLE RESPONSE TERHADAP KECAMBAH TIGA VARIETAS KACANG HIJAU ABSTRAK Pembudidayaan tanaman kacang hijau selalu terkendala dengan keadaan lahan yang terbatas. Tanaman kacang hijau di tanam dengan tumpang sari, sehingga mengakibatkan tanaman ini tumbuh dengan keadaan ternaungi. Naungan ini menyebabkan naiknya produksi etilen, sehingga menimbulkan triple response yang dapat mempengaruhi pertumbuhan dan perkembangan tanaman. Oleh karena itu hal ini menjadi alasan dilakukan penelitian ini dengan etilen pada tiga varietas kacang hijau yaitu VIMA I, Seriti dan Kutilang. Setelah dikecambahkan tujuan untuk menyeleksi varietas kacang hijau yang tahan dengan adanya peningkatan jumlah selama 5 hari, panjang kacang hijau varietas VIMA I yang diberi karbid (penghasil etilen) adalah yang tertinggi. Bengkokan varietas kacang hijau yang terendah adalah varietas VIMA I. Namun untuk diameter kecambah ketiga varietas tidak berbeda nilainya baik yang diberi karbid maupun yang tidak diberi karbid. Dari penelitian ini menunjukkan varietas VIMA I adalah tanaman yang tahan terhadap peningkatan etilen, sehingga varietas ini berpotensi untuk ditanam di naungan. Kata Kunci :Etilen, Triple Response, Kacang Hijau STUDY OF ETHYLENE TRIPLE RESPONSE ON SEEDLINGS OF THREE VARIETIES OF MUNGBEAN ABSTRACT Grow green beans are always constrained by the state of limited land. Thus the green bean crop planted with intercropping, resulting in these plants grow with shady circumstances. However, this shade causes increased production of ethylene, causing triple response which can affect plant growth and development. Therefore this is the reason of this research with the aim of selecting resistant varieties of green beans with the increased amount of ethylene on three varieties of green beans that VIMA I, Seriti and Kutilang. Once germinated for 5 days, the length of green beans varieties by VIMA I carbide (ethylene producer) is the highest. And bend varieties of green beans were the lowest observed varieties VIMA is I who have given carbide. But for the three varieties of sprouts diameter does not vary in value whether it is given or not given acetylene carbide. From this research shows VIMA I is a plant varieties that are resistant to an increase in ethylene, so that this variety has the potential to be planted in the shade.

Vegetable yield is positively related to the environment and negatively affected by the pot root restriction during both the nursery and post-transplant stages. Root restriction is a physical stress imposed on the root system when plants are grown in small containers, which leads to a pronounced decrease in root and shoot growth at both the transplant and pot stages. Based on the assumption that the plant responses are mainly associated with a negative hormonal signaling from roots, some researchers have proposed that these abiotic stresses may be overridden by using a pre-transplant spray with benzyl amino purine (BAP), a synthetic cytokinin able to regulate plant metabolism. Although the physiological mechanisms induced by BAP have been described, the implementation of commercial applications of BAP for vegetables is still a pending issue. The aim of this work was to analyze growth changes in four lettuce genotypes in the presence of different root restrictions degree by the use of different plug cell volumes but sprayed with a single BAP spray under the hypothesis that it would play a role as abiotic stress alleviators. Our results showed that the higher biomass accumulation in lettuce plants non root-limited and BAP-sprayed ones are supported by higher photosynthetic rates, by higher leaf number initiation and expansion and by photo assimilate partition to shoots. Understanding the plant responses to this hormonal manipulation and the physiological mechanism involved will allow adjusting the agronomic advice for different vegetables and reaching commercial yields to each of them.

Coffee (Coffea spps.) is the second most traded commodity in the world after raw oil. Coffee is grown in mid hills of Nepal from an altitude of 700masl to 1500masl under different shade management practices. Nepalese coffee farmers grow coffee in a traditional way with almost zero application of inorganic fertilizers, pesticides and hence Nepalese coffee is popular as organic coffee or specialty coffee in the world. A study was carried out in three Coffee potent adjoining districts of Nepal: Gulmi, Syangja and Palpa. Ripe coffee cherries were harvested from every 200m altitude from 700masl to 1500masl under shade management and without shade management practices. Different physical attributes such as 1000 cherry weight, wet parchment weight, dry parchment weight, green beans weight, defected beans, and green bean diameter were observed. Production from each altitude level was recorded and highest production (7.04 kg per plant) was obtained from an altitude of 900-1100masl . The highest 1000 cherry weight (1297.17g) and the highest green bean weight (450.33 g) were obtained from 900-1100masl. Under no shade management, number of defected beans were 98 per 1000 beans whereas it was 64 under shade. The interaction of altitude and shade management practice had significant effect upon production (P=0.035), 1000 cherry weight (P<0.001), dry parchment weight (P=0.049) and green bean weight (P<0.05). Coffee produced at an altitude of 900-1100masl under shade management practice were found to have higher production and of better quality with fewer defected beans whereas that produced at extreme lower of 700-900masl and extreme higher altitude of  1300-1500masl were found to have lower production and poor quality.

C2H2 zinc finger proteins (ZFPs) play important roles in plant development and response to abiotic stresses, and have been studied extensively. However, there are few studies on ZFPs in mangroves and mangrove associates, which represent a unique plant community with robust stress tolerance. MpZFP1, which is highly induced by salt stress in the mangrove associate Millettia pinnata, was cloned and functionally characterized in this study. MpZFP1 protein contains two zinc finger domains with conserved QALGGH motifs and targets to the nucleus. The heterologous expression of MpZFP1 in Arabidopsis increased the seeds’ germination rate, seedling survival rate, and biomass accumulation under salt stress. The transgenic plants also increased the expression of stress-responsive genes, including RD22 and RD29A, and reduced the accumulation of reactive oxygen species (ROS). These results indicate that MpZFP1 is a positive regulator of plant responses to salt stress due to its activation of gene expression and efficient scavenging of ROS.
