“…In the present study, the production of bigger fruits produce by the plants of BC-1 (Simen Chapori) might also be due to higher chlorophyll index values leading higher production of photosynthates enabling the plant to produce bigger fruits. The present finding is in conformity with Mahajan and Dhillon (2000) [20] and Kumar et al (2014) [13] . Variations in fruit length and width due to different factors have also been reported by Aulakh et al (2005) [2] ; Dhanumjaya and Subramanayam (2010) [8] .…”

An experiment was carried out during 2017-19 to study the morpho-physical and bio-chemical characters of Thai Apple ber (Ziziphus mauritiana Lamk.) grown in Assam. The leaves of Thai Apple ber fruits collected from different locations of Assam showed elliptic shape with serrate leaf margin, obtuse apex and oblique base. The colour of mature leaves was observed to be dark green. The leaf length, leaf breadth and petiole length of Thai Apple ber fruits shows a great variations among all collection. The plant of Gela Pukhuri and Simen Chapori recorded early flowering and harvesting among the Thai Apple ber plants of other locations in the present study. The fruits of Boitamari (BC-8) recorded longest fruit (5.10cm) while, maximum fruit weight (53.08g) was recorded in BC-1 (Simen Chapori). The shape and surface of seeds was found to be ovate and warty and pulp-stone ratio ranged from 18.76 -23.28.The biochemical analysis reveals that the quality characters like moisture content, TSS, titratable acidity, TSS-acid ratio and ascorbic acid content differed. Total sugar (6.37 -7.81%) and reducing sugar (2.44 -3.06%) contents varied significantly among the Thai Apple ber fruits of different locations. The highest vitamin A (16.08 μg/100g) were found in Gela Pukhuri (BC-3) and highest protein (0.87g/100g) was found in BC-2 (Bongalmora). The calcium and phosphorus contents of the Thai Apple ber fruits ranged from 20.48mg/100g to 23.50mg/100g and 24.08mg/100g to 25.25mg/100g, respectively. It can be concluded that Thai Apple apple ber fruits can successfully be grown under sub-tropical area of Assam. The ber fruits collected from Simen Chapori (BC-1) was found best in terms of biochemical composition i.e. TSS, TSS/ acid ratio, total sugar, reducing sugar and moisture content.

“…The number of sunshine hours has decreased annually since 1953 in the study area [ 29 ], with a similar trend being documented in other areas of China [ 38 , 39 ] and worldwide [ 40 – 42 ]. Fewer sunshine hours in April and August may affect photosynthesis and reduce the speed of fruit growth, in addition to decreasing ascorbic acid and sugar content in the fruit [ 41 ]. The PDT model uses relative sunshine-hour effectiveness (RSE) to explain the sunshine hour effects on fruit size.…”

In apple cultivation, simulation models may be used to monitor fruit size during the growth and development process to predict production levels and to optimize fruit quality. Here, Fuji apples cultivated in spindle-type systems were used as the model crop. Apple size was measured during the growing period at an interval of about 20 days after full bloom, with three weather stations being used to collect orchard temperature and solar radiation data at different sites. Furthermore, a 2-year dataset (2011 and 2012) of apple fruit size measurements were integrated according to the weather station deployment sites, in addition to the top two most important environment factors, thermal and sunshine hours, into the model. The apple fruit diameter and length were simulated using physiological development time (PDT), an indicator that combines important environment factors, such as temperature and photoperiod, as the driving variable. Compared to the model of calendar-based development time (CDT), an indicator counting the days that elapse after full bloom, we confirmed that the PDT model improved the estimation accuracy to within 0.2 cm for fruit diameter and 0.1 cm for fruit length in independent years using a similar data collection method in 2013. The PDT model was implemented to realize a web-based management information system for a digital orchard, and the digital system had been applied in Shandong Province, China since 2013. This system may be used to compute the dynamic curve of apple fruit size based on data obtained from a nearby weather station. This system may provide an important decision support for farmers using the website and short message service to optimize crop production and, hence, economic benefit.

“…Recent studies have revealed that the environmental factors viz. temperature, light intensity, soil moisture content and atmospheric humidity have a strong influence in its production trends and fruit quality (Kumar, 2014). The prevalence of dry, frost free winters, hot summers with high humidity and abundant rainfall is crucial for commercial crop production.…”
