Propagation of Himalayan maple (Acer caesium Wall.) through seed and softwood cuttings was investigated to standardize nursery techniques for mass production of the species. The seedlings were raised from viable seeds in different containers filled with different combinations of growing media. Vegetative propagation of softwoodcuttings was carried out by treating with different combinations of IBA and Willow leachate of different durations. The statistical analysis revealed the differential behaviour of various nursery stocks with respect to survival, growth and biomass. The growing media soil:sand:vermicompost (2:1:2) and container (root trainer 300 cc) showed maximum germination (61.00%), seedlings height (35.17 cm), collar diameter (5.07 cm), shoot:root ratio (1.24) and survival percentage (76.33%). Conversely, the cuttings treated with IBA @ 8000 ppm showed maximum sprouting (74.50%), rooting (66.75%), length of longest root (14.65 cm), no. of roots per cutting (33.00%), shoot length (13.90 cm) and survival percentage (41.50%). Hence, the seeds of the species should be grown in Rot trainer of 300 cc having soil:sand:vermicompost (2:1:2) to get good quality planting materials. However, the softwood cuttings should be given treatments with IBA @ 8000 ppm for mass production of plants vegetatively.

Rind colour and taste are important factors influencing consumer acceptance of mandarins (Citrus reticulata Blanco) fruit. In this experiment, the influence of fruit canopy position and harvest date on the fruit rind colour and other quality parameters of Imperial mandarins was investigated. The mandarin fruit were harvested from four different positions in the tree canopy i.e., upper-inner, upper-outer, lower-inner and lower-outer and at three different harvest dates (H1 (five days before commercial harvest date); H2 (commercial harvest date) and H3 (five days after commercial harvest date). The experiment was conducted using a two factors (fruit position and harvest time) factorial randomised block design with four replicates and fifteen fruit per replicate. Rind colour and the quality of Imperial mandarins were significantly affected by the fruit position in the tree canopy, with the fruit harvested from the upper canopy having better rind colour and higher levels of organic acids and sugars compared to other positions. The late harvested (H3) mandarins exhibited the best fruit colour. In conclusion, the Imperial mandarin fruit had better fruit colour as well as quality when harvested from the upper canopy and by delaying the fruit harvest date by five days from the original commercial harvest date.

Nusantara Bioscience 10: 178-182. Yellow bamboo (Bambusa vulgaris Schrad Ex. var. Striata) is one kind of bamboo used for industrial and household raw materials. Yellow bamboo propagation with branch cuttings has relatively low percentage of growth. To increase the growing success of yellow bamboo branch cuttings can be used growth regulators substance, such as NAA and coconut water. This study aimed to obtain the best combination of NAA and coconut water with the soaking duration in the growth of yellow bamboo branch cuttings. The study was conducted using Completely Randomized Design (CRD) of 6 × 3 factorial arrangement with five replications. The first factor was the combination of NAA and coconut water (CW), which consisted of six levels, namely 100% CW, 20% NAA + 80% CW, 40% NAA + 60% CW, 60% NAA + 40% CW, 80% NAA + 20% CW and 100% NAA. The second factor was the soaking duration which consists of three levels, namely 12 h, 24 h, and 36 h. Parameters observed included shoot emerging time, shoot number, shoot length, leaf area, root number and root length. The data obtained were analyzed using the Analysis of Variance (ANOVA) and Duncan's Multiple Range Test (DMRT) α=5%. The results showed that the combination of 80% NAA + 20% CW gave the best yellow bamboo branch cuttings growth with an average shoot length of 1.44 cm, leaf area 41.29 cm2, root number 42.87 and root length 23.70 cm. The interaction of 80% NAA + 20% CW with soaking duration of 36 h resulted in average the fastest shoot emerging time of 2.02 days after planting.
