Dynamic Growth

Kandelia candel, Aegiceras corniculatum and Avicennia marina are the dominant plant species of Quanzhou Bay Estuarine Wetland. In this study, we had established the four-parametric logistic equations of plant height, tree crown diameter and leaf length versus the time after they were transplanted (sowed). The development pattern of the wetland plants was different among species and locations. The growth parameters estimated using four logistic equations is able to provide detailed plant dynamic growth information for Aegiceras corniculatum, Kandelia candel and Avicennia marina. By comparison, it is difficult to assess the adaptability of Kandelia candel to the environment of the region whether the upstream or downstream. However, we can deduce that Avicennia marina is suitable for growing in the upstream and downstream of Luoyang River, not in the midstream. The results will provide scientific basis for the allocation and arrange on plant species in the wetland.

Mangrove species, viz., Avicennia officinalis, Avicennia marina var. acutissima, Avicennia marina (dwarf), Rhizophora mucronata, Sonneratia alba, Aegiceras  corniculatum, Kandelia  candel were chosen for measurement of height of the tree and girth or circumference. The sampling was random and at least 50 records were made. The girth is measured by the tape. The measurement of the height is made with the help of abny level. The Tables 1 to 8 records the values for girth, height and canopy cover as well as for correlation coefficient (r). There correlation between girth and canopy in all the species studied however in case of Avicennia officinalis and Aegiceras corniculatum girth and height show more co-relation than girth and C. cover. The positive co-relation observed between girth and canopy is more or less 0.7 except Avicennia marina (dwarf) Excoecaria agallocha and Aegiceras corniculatum. The co-relation is observed in girth and height is difficult to explain. This case is observed in Avicennia officinalis and Aegiceras corniculatum.

The research was conducted at Beltari Sandhikharka-10, Arghakhanchi district to study about the effect of various doses of boron on growth and yield attributing characters of cauliflower (Brassica oleracea var. botrytis) during off-season from February to June in 2020. Five treatments; B0 (control/no application), B1: 2kg/ha, B2: 4kg/ha, B3: 6kg/ha, B4: 8kg/ha which are the different doses of boron application were laid out in Randomized Complete Block Design (RCBD) with 4 replications. The growth parameters like plant height, number of leaves per plant leaf length and leaf breadth of largest leaf were recorded multiple times with 15 days interval. Days to curd initiation and Days from curd initiation to harvest were recorded by regular field observation. The yield parameters; curd weight with leaves, Marketable curd weight, average curd yield, incidence of hollowing were recorded during harvest. The economics from application of boron doses in cauliflower production was obtained in terms of cost of cultivation, gross returns, net returns, and benefit cost ratio. The result showed that the growth and yield attributing characters of cauliflower were significantly affected by application of boron in which the value of these parameters was found significantly higher in B1 followed by other treatments. The average curd yield of cauliflower in B1 was found to be 12.39 mt/ha which was 48.92% higher than that of B0 with curd yield 8.32 mt/ha. Similarly, the net return was found significantly the highest in B1 and the lowest in B0. The result showed that application of boron in the range of 2-4 kg/ha is preferred to control and higher doses in respect of both productivity and economics.

This study used different supporting media (poly-styrene sheet, sand, and gravel) during outdoor hydroponic farming of onion within a natural environment setup. Domestic onion variety Taherpuri was taken as a model onion plant. As for performance parameters, plant height, number and length of leaf, length of root, bulb weight, number of bulblet, and chlorophyll contents were recorded. The number of produced leaves was almost same, although the length of leaf and root was found to have variations in these three supporting media. The yield (weight of bulb and number of bulblet) performance was slightly higher in polystyrene sheets (7.74 g and 3 bulblets per plant) than in the others. Chlorophyll-a, Chlorophyll-b, and total chlorophylls were comparatively higher in polystyrene sheets, 0.530, 0.764, and 1.294 mg/g respectively. Other growth parameters also showed better results in the case of polystyrene sheets. Finally, the results suggested that the polystyrene sheet as a hydroponic floating bed is suitable for outdoor hydroponics for onion cultivation.

Begonia is very popular as a foliage plant and some begonia species grow up in pots. Begonia serratipetala and Begonia muricata are Indonesian begonia species that are well suited as indoor potted plants because of their leaf color and shape. In addition, the Bali Botanical Garden's landscape nursery would like to use these begonias for decoration in all buildings. However, it still needs to be studied how long the shelf life of the two begonias is in indoor environments in the highlands without air conditioning (AC). The aim of this study was to investigate the indoor shelf life of B. serratipetala and B. muricata. This research method consists of two steps. The first step was the acclimation phase and the second step was the indoor placement phase. Each begonia was repeated three times. Parameters studied included plant growth (plant height, leaves, leaf width, and leaf length) and environmental factors (sunlight intensity, air temperature, and humidity). The data were analyzed descriptively. Correlation analysis was used to determine the relationship between growth parameters and environmental factors. The result showed that both begonias (B. muricata and B. serratipetala) have similar persistence to indoor begonia species within two weeks, the ideal time for plant replacement

The study was conducted in the Pragatisil Community Forest, Kaski District, Nepal in 2012 to assess the regeneration status of Sal (Shorea robusta) seedlings, its growth and plant diversity. A plot size of 25 m × 20 m was employed for trees, 10 m ×10 m for poles and 5 m × 5 m for regeneration. The growth parameters measured were dbh and height. A factorial arrangement of treatments was employed; the treatments being slope and aspect. The results showed that there was significant (p<0.05) effect of slope on dbh and basal area whereas there was no effect of aspect on growth parameters measured in the Pragatisil Community Forest. The regeneration of Sal was satisfactory (6,126 seedlings/ha), and there were 32 plant species in this forest. As there was higher basal area per ha in the Pragatisil Community Forest, it is recommended to have thinning of 40% of basal area for enhancing growth of remaining stems.Banko Janakari, Vol. 23, No. 2, 2013

The experiment was carried out to determine the effects of heat stress on some growth parameters like shoot height, leaf area, fresh weight, dry weight as well as the accumulation of chlorophylls in Carica papaya. Seedlings of C. papaya were exposed to prior heat stress at 40 °C. A group of plants was placed in a Gallenkamp oven for four hours; another group of plants was placed in the oven for eight hours while the third group of plants was placed in a dark cupboard for the period of eight hours. Sampling was carried out at weekly intervals starting from seven days after treatment. Plants were randomly picked from each of the three treatments. Three replicates were used for each parameter. The results obtained from the study showed that there was an increment in the shoot height, leaf area, fresh weight and dry weight from the beginning to the end of the experimental period. However, the accumulation of chlorophylls did not follow a particular pattern. The analysis of variance carried out on the data obtained showed that heat stress had a significant effect on the petiole length, shoot height, leaf length, leaf width, leaf area, fresh weight and dry weight. Heat stress, however, did not produce a significant effect on the accumulation of chlorophylls a and b and total chlorophyll.
