Parameters of Physical and Physiological Quality in Seed Produced during High Season for Different Periods of Development

Objective: To evaluate the quality of seeds tomato fruits (Solanum lycopersicum Mill.) produced in high temperture (HT) during different phases development. Design/Methodology/Approach: Seeds Moneymaker variety were planted a ventilated greenhouse (control treatment, CT) with maximum mean temperature (MMT) 31.5 °C. A second artificial heating (MMT 36.5 ºC) was used for HT treatments. When anthesis began from fourth floral cluster, seven treatments established: T1) growing permanently CT; T2) transferred to between five and 12 days after (daa); T3) 24 daa; T4) 24-36 daa HT; T5) 36-48 T6) 48-60 T7) 60 maturity HT. Results: The weight one thousand (SW) had positive correlation length seed (R=0.83*), indicating that increase SW primarily determined by an length. vigor measured germination accelerated ageing (GAA); thus, are positively correlated respiration (0.62* 0.81*, respectively). Study Limitations/Implications: impacting on phase development could decrease both physical physiological seeds. Findings/Conclusions: T7 lower (2.99 g). T5 caused amount per fruit (120), (79.4 %) GAA (39.5 %).
