Studies of Phenological growth stages of different Psidium guajava L cultivar through BBCH scale under subtropical condition
Phenological growth stages of different varieties (Lalit, Shweta, Allahabad Safeda, Dharidar and HPSI 46) guava was observed according to BBCH scale and the data were recorded in different stages in days. Earliest Bud swelling, bud growth begins and first leaves sprouting was found earliest Dharwar. Minimum number of days taken for leaves unfolded in Cv. HPSI 46, minimum days was recorded to complete leaves development in cultivar shweta, while Allahabad Safeda showed earliest flower buds. Least days taken to express of first flower buds, flower petals elongating and sepals totally opened found by cultivars Shweta, Lalit and Allahabad Safeda respectively. The minimum days required by cultivars Shweta and Allahabad Safeda to produce 50% flowers open, petal fall and fruit setting respectively.
3D PRINTING OF BOVINE HEART BY USING POLYURETHANE MATERIAL
The core of veterinary anatomy is the study of three-dimensional animal body structures. The study of veterinary anatomy has traditionally served as the cornerstone of all disciplines in human medicine, veterinary medicine, and animal sciences. A classic anatomy lesson would involve didactic lectures utilizing chalk and talk, PPT presentations, the teacher doing a prosection, and the students performing a dissection. Creating 3D anatomical specimens, helps instructors and students to get rid of laboratories and museums which are filled with formalin specimens and their vapor. This study revealed a novel method for CT scanning and DICOM file generation for creating raw rasterized data. Additionally, the data were converted into STL (Standard Tessellation Language) files, allowing for simple 3D printing. The new technology was used to print an ox heart using Polyurethane(TPU) filaments through FDM and SLA-type 3D printers without sacrificing quality. Every person has the right to a healthy lifestyle. In this setting, 3D-printed teaching materials are a godsend for pedagogy. In this research, the materials, processes, and benefits of 3D printing of biological specimens for veterinary anatomy were examined. Creating veterinary anatomy specimens using 3D printing technology is undoubtedly the start of a new era in veterinary anatomy education.
Evaluation of bottle gourd variety Thar Avani under rainfed semi-arid conditions for morphological traits along with antioxidant potentiality and mineral content
The present study was conducted at ICAR-Central Horticultural Experiment Station (CIAH-RS), Godhra, Gujarat during 2021-2022. The correlation coefficients among antioxidants, nutritional and physiological traits of bottle gourd varieties calculated and summarized by using the BLUPs. A strong positive correlation was found in CUPRAC with DPPH (r=1.00; P≤0.01). High mag-nitude and non significant correlation was found in TF with CUPRAC and DPPH (r = +0.96). Among 29 physiological traits in bottle gourd varieties, highly significant correlation in FL and FW with FG and NFMF, respectively (r=+1.00; P≤0.05) were observed. Likewise, FW with FL (r=+1.00; P≤0.001). High magnitude and significant correlation was found between IL and LPL (r=+1.00; P≤0.01).

Standardization of seed germination and assessment of quality traits of Moringa oleifera seedlings grown in different substrates under dryland semi-arid conditions
The present study was aimed for standardization of seed germination and assessment of quality traits of Moringa oleifera seedlings grown in different substrates under dryland semi-arid conditions. PCA using the twenty seven traits of eighteen treatments of M. oleifera indicated that 90.16 % variability was accounted for the first four principal components (PCs) with eigen values ≥1 (Fig 2-4). The 1st principal component (PC1) had an eigen value of 12.00 and explained 44.43 % of the total variation. The second component (PC2) explained 27.30% of the total variance with an eigen value of 7.37 and explained 71.73 % of the total variation. G6DAS and G8DAS with G6DAS, G8DAS with G6DAS, G12DAS and G14DAS with G10DAS, G14DAS with G12DAS, SSNS45DAS and LL45DAS with SSEW45DAS, LL45DAS with SSNS45DAS, P and K with DM, K with P, Mg and DPPH with Ca, DPPH with Mg were significantly and highly correlated r = +1.0. High magnitude and significant correlation were found between St45DAS and G10DAS, St45DAS and Se45DAS, ViC with SSEW45DAS, SSNS45DAS & LL45DAS, TF and ViC, TP & TF with Ca & Mg, DPPH with TP & TF, CUPRAC and FRAP r = +0.9. The inter cluster distance (D) ranged from 770.33 to 1590.58. The intra cluster distance (D) ranged from 142.25 to 957.11. cluster I had maximum mean value for sixteen traits viz. G4DAS, G6DAS, G8DAS, G10DAS, G12DAS, G14DAS, Se45DAS, St45DAS, LNS45DAS, Mo and Fe and minimum mean value for LNL45DAS, Mo, P, K and TF while moderate mean value for traits SSEW45DAS, SSNS45DAS, LL45DAS, ViC, Ca, Mg, TP, FRAP, CUPRAC and DPPH. The maximum germination was recorded in cluster I.
Genetic analysis of gynoecious parthenocarpic cucumber lines for growth, yield and quality parametrs under polyhouse conditions.
The experiment was carried out to assess the genetic variability, character association and path analysis infifteen gynoecious parthenocarpic hybrids/lines of cucumber under polyhouse (fifty percent shade/naturally ventilated) conditions. The genotypic and phenotypic coefficient of variations were highest for nodal position of first female flower (48.44 and 51.04),number fruits (40.99 and 41.24), fruit weight(26.40 and 27.39) and fruit yield per plant(38.22 and 38.93). High heritability coupled with High genetic advance as per cent mean was observed for most of the characters, indicating that these characters are controlled by additive gene action. The fruit yield per plant showed significant positive correlation with an number of fruits per plant (0.819 and 0.825), plant height (0.302 and 0.303) and significant negative correlation with days to fifty percent flowering (-0.682 and -0.707), nodal position of first female flower (-0.652 and -0.716) and days to first female flower (-0.373 and -0.379) both at phenotypic and genotypic. maximum positive direct effects towards fruit yield per plant was contributed by days to fifty percent flowering, number of fruits per plant and fruit weight were the most influencing factors. The hybrids namely Vally Star, Multi Star, Silyon and Pune collection were the best with respect to earliness, superior quality as well as maximum yield.
